Cold hardy yucca plants

Choosing the Best Companion Plants for a Yucca

Yucca plants are enchanting additions to a home or garden. They are indigenous to the Americas and grow naturally in the arid, desert climates of the American South and Mexico. Most unique about Yucca plants is their pollination process, which is entirely dependent upon a symbiotic relationship with an organism called the Yucca moth. Planting tiger lilies and other resilient species along with your Yucca plants can be a great way to enhance your garden space.

If you know that you would like to plant a variety of Yucca in your garden, familiarize yourself with the sunlight and soil needs of Yucca plants to make the best choice for companion plants. Read on to learn about the basics of Yucca plant growth and blossoming.

Yucca Plant Climate and Sunlight Requirements

Yucca plants grow naturally in harsh, dry climates with ample sunshine and minimal water. Although juvenile Yucca plants are fragile and susceptible to weather and atmosphere, adult Yuccas are hardy plants that can survive in a variety of climates.

Plant your Yuccas in a mixture of half soil and half sand to emulate the desert climate that is their native home. Additionally, Yuccas need full sunlight for most of the day, although it may be beneficial to have partial shade in the afternoon while the flowers are blooming in the spring and summer in order to preserve them. Water your plant regularly but not often.

Typically, Yucca plants require little to no care once they have settled and established a root system. In fact, many people find that their Yucca plants tend to take over their garden if they fail to trim them back each year.

Companion Plants for Yuccas

Pair your Yucca with equally resilient plants that have similar soil and sunlight requirements. Tiger Lilies, Sedum, Rudbeckia, Sage and Yarrow all thrive in similar conditions and bloom at the same time as Yucca. These plants look beautiful next to each other and will produce a huge number of flowers during the late spring and summer.

Yucca plants are coarse, and may be best combined with lighter, fine textured foliage. Sedum, Ceratostigma, Coreopsis and many types of grass provide an excellent contrast with the spiky leaves and bristles of the Yucca plant.

Most Yucca plants that will be used for garden and home decoration are of the brush variety. Some Yuccas grow in a tree-like configuration, featuring a trunk and distinct limbs. Brush-type Yucca plants grow short and stout, and may be best paired with taller plants or species that are more vine-like for contrast.

Yucca plants can outgrow other species sharing the same flower bed if you are not careful. Take precautions against this by trimming your Yucca plant back considerably each year. The plant will bloom at the cut point at the beginning of the summer. Doing this will help to clear the way for companion plants that can help to highlight the natural beauty of the Yucca, and ensure that your garden is inviting and attractive for years to come.

The Garden Guru: Color Guard yucca stands supreme year round

This is typically the time of the year I might tout hollies, conifers or even poinsettias, but as I was walking around a dark and dreary, rainy garden today it was a cluster of Color Guard yuccas that stood like beacons of welcoming color. If you are not familiar with Color Guard, it is the best selection of our native Yucca filamentosa.

You may be thinking yucca and native doesn’t pair up for Georgia, but I’ll bet dollars-to-donuts that you didn’t realize that this plant known as Adam’s Needle was native from Texas to Michigan and from New York down the east coast to Florida. That’s right, it is native in 29 states, meaning just about anybody can grow it.

For years I traveled to California and came back lamenting that we couldn’t grow Phormium or New Zealand flax like they do and that the Cordyline was more than temperamental. This is not be the case with this colorful plant sporting native DNA and can take every winter or summer Georgia can dish out.

Color Guard yucca will reach 2 feet in height and 2 feet wide – perfect for creating garden excitement with green and gold variegated foliage and dagger-like foliage. As you might expect from a native, it is an extremely drought-tolerant plant that requires good drainage. If your soil is clay or muck that holds water, then by all means improve your soil and plant on raised beds.

Just outside of our cottage garden, we have them planted on raised beds and grown in combination with Prince Sago cycad (Cycas taitugensis) and torch lilies (Kniphofia). I’ve also grown them in very non-traditional companionships with tall angel’s trumpets and bananas, and a friend of mine partnered them with the lycoris or red spider lily. You will find the Color Guard will work in almost every imaginable situation, just be bold and give it a try.

Though I love the green and gold of Color Guard, know that there are also great blue selections like Hofer that allow even more creativity in combinations and mixed planters.

I may be raving about the foliage and architectural aspects in the garden, but each spring to early summer, another amazing site takes place as creamy white, lightly fragrant blooms are borne on 6-foot-tall stalks. These blooms are found to be a most delectable source of nectar for hummingbirds. As is typical of the agave family, it dies after blooming, but new pups (lateral shoots) form around the edges of the dying plant.

It is a rare week that goes by that someone doesn’t ask me about deer-resistant plants. If you find yourself the proud owner of a roving herd, then rejoice; the Color Guard yucca will not become Bambi’s salad. The Color Guard yucca is showy 12 months of the year, the color doesn’t fade or bleach, and I assure you on cold, dreary day it is the plant that will command attention.

Zone 4 Yucca Plants – What Are Some Winter Hardy Yuccas

Adding a touch of desert elegance to the northern or cold season garden can be challenging. Lucky for those of us in cold zones, there are winter hardy yuccas which can withstand temperatures of -20 to -30 degrees Fahrenheit (-28 to -34 C.). These are zone 4 average cold temperatures and require one of the cold hardy yucca varieties if you wish your plant to survive winter. This article will detail some of the zone 4 yucca plants suitable for such chilly climes.

Growing Yuccas in Zone 4

Southwestern plants are appealing due to their diversity and adaptability. Yuccas are primarily found in the tropical to subtropical Americas and tend to prefer warm, dry regions. However, there are some cold hardy yucca varieties which are suitable for extreme cold temperatures.

In fact, even though we associate these relatives of Agave with desert heat and dryness, some forms have been found growing in the crisp region of the Rocky Mountains in winter. You just need to make sure you choose an appropriate variety with cold tolerance and adaptability to freezing temperatures.

Simply selecting cold hardy specimens is no guarantee they will thrive in such extreme weather conditions. Heavy snow can damage foliage and deep freezes that are longer than

a week can adversely affect roots of shallowly planted yucca. Some tips can help successfully grow yuccas in zone 4.

  • Planting your yucca in a microclimate in your garden can help protect the plant from some of the cold temperatures.
  • Using a southern-facing wall or fence can help reflect winter sun and produce a moderately warmer region. It also reduces the plant’s exposure to cold northerly winds.
  • Do not water plants before a hard freeze, as excess moisture in the soil can turn into ice and damage the roots and crown.

In extreme cases, growing yuccas in zone 4 may require more obvious protective steps. Use organic mulch around the root zone in a layer of up to 3 inches and protect plants in exposed situations by placing plastic over the entire plant during the night. Remove it during the day so moisture can escape and the plant can respirate.

Zone 4 Yucca Plants

Some yuccas can grow into trees, such as the Joshua tree, while others retain a tidy, low rosette perfect for containers, borders and accent plants. The smaller forms are usually hardy in areas with consistent snow and freezing temperatures.

  • Yucca glauca, or small soapweed, is one of the best winter hardy yuccas and has lovely narrow bluish green leaves. The plant is hardy in much of the Midwestern United States and can withstand temperatures of -30 to -35 Fahrenheit (-34 to -37 C.).
  • The tidy little 2-foot-tall Yucca harrimaniae, or Spanish bayonet, has very sharp leaves as the name suggests. It is drought tolerant and thrives in cold winter regions.
  • The dwarf yucca, Yucca nana, seems made for container growing. It is a neat little plant of only 8 to 10 inches in height.
  • Adam’s needle is a classic cold hardy yucca. There are several cultivars of this zone 4 plant, Yucca filimentosa. ‘Bright Edge’ has gold margins, while ‘Color Guard’ has a central cream stripe. Each plant approaches 3 to 5 feet in height. ‘Golden Sword’ may or may not be in the same species depending upon who you consult. It is a 5- to 6-foot tall plant with narrow leaves sliced through the center with a yellow stripe. These yuccas all produce flower stalks decorated with creamy bell-shaped flowers.
  • Yucca baccata is another cold hardy example. Also known as banana or Datil yucca, it can survive temperatures of -20 degrees Fahrenheit (-28 C.) and possibly colder with some protection. Plants have blue to green leaves and may produce thick trunks.

Introduction to Yuccas

This is an Agave-like plant that, in general, has more cold tolerance than most Agaves, though there are some cold intolerant species (and a few fairly cold tolerant Agaves as well). These are arid-loving, rosette-shaped flowering plants that consist of primarily lanceolate leaf blades with very sharp leaf tips. Some Agaves and Yuccas are hard to tell apart, though Agave and Yucca flowers look very different. Most Yuccas are stemmed plants, but quite a few are not. Most Yuccas flower repeatedly, but a few are monocarpic (flower once, and then die) like most of the Agaves. The flowers of Yuccas are generally large and showy, are white or pale yellow (some exceptions) and are pollinated by moths that are only attracted to Yucca flowers (this makes propagation by seed in my yard difficult as these moths are probably not in large numbers in urban landscapes).

Some Agaves can look a lot like Yuccas… or vice versa. The first two are Agaves (Agave schidigera and Agave mutilfilifera); Last photo is of Yucca elata (photo by Xenomorf)

Three more Yucca-like plants: Furcraeas are often stemmed like some Yuccas (Furcracea selloa in first photo and Furcraea macdougallii in second); Dasylirions are also Yucca-like, but most have teeth along the leaf blades which Yuccas never have (Dasylirion wheeleri in last photo on right)

Three more Yucca-look-alikes: Dracaenas (like this Dracaena cinnabari and Dracaena serrulata in first two photos) and Hesperaloe parviflora in the third photo

Without any exceptions I am aware of Yuccas are full sun plants (some survive in shadier locales, but would probably prefer full sun) and I have lost a number of Yuccas from too little sunlight. These plants also seem to love high, dry heat, though some cultivars are not in this group. Some Yuccas excel in humid climates, but most prefer a dry climate. Though some Yuccas are not cold tolerant, few Yuccas are too tropical in their needs to survive in most areas of Southern California. Some species tolerate USDA zones as low as 4 (-30F or -34C) while others have problems in zones below 9b (25F or -4C). This an excellent species for low rainfall and/or high wind zones where so many other plants struggle. Though most prefer well draining soils, many obviously tolerate clayey, poorly draining soils as well.

Yuccas are a plant that, as a child, I had no love for. Hiking through the valleys, deserts and mesas of New Mexico, I was often careless enough to be jabbed by the local Yucca species. Tthey were everywhere and were not–to me–an overly ornamental species. The name Yucca brings to mind a low, shrubby pale green dangerous array of pointed spines I had to constantly avoid. But I have since learned some Yuccas are indeed beautiful plants and definitely worthy of desertscape potential, as well as useful for outdoor pots and planters.

Yuccas have a number of uses, including food (human and feedstock), sewing and basket weaving, a shampoo and soap ingredient, a natural dye, and for a number of medicinal uses. The following are some Yuccas commonly found in cultivation

Yucca aloifolia (Spanish Bayonet, Dagger Plant) This is a U.S. native but also grows in Mexico and the West Indies. Yucca aloifolia is a thicket-forming plant with very sharp, stiff, rough-surfaced leaf blades, with the old leaves browning, pointing down and drying plastered against the stems in a long petticoat of dead leaves. Stems are up to twenty feet high, though most tall plants eventually topple and grow laterally for a while before growing upright again. The variegated forms are far more popular in cultivation than the normal green forms. This is a zone 8 to 11 plant. For more, see this Floridata webpage.

Yucca baccata (Banana or Datil Yucca) This is a native of the U.S. Southwest and Mexico, where is relatively common. It is also used fairly commonly as an accent plant, but rarely as a specimen plant (only older, stemmed plants have remarkable specimen potential). It is one of the wider-leaved Yuccas and has ornamental pendulous whitish flowers that only very vaguely resemble bananas. Most have dull green leaves, but some forms have bluish leaves. It is a very cold hardy species surviving in USDA zone 5 (-20F or -29C) or possibly even colder.

Yucca brevifolia (Joshua Tree) This southwest native literally grows in forests in some areas of California and are one of the classic symbols of the California desert (it is to the California desert as the Saguaro Cactus is to the Arizona desert). This is probably the largest of the North American Yuccas growing up to fifty feet or more (usually topping out around thirty feet). It is a stiff, short, pale to lime-green leaved species with a wonderful randomly branching habit. Plants are extremely drought and heat tolerant but require excellent drainage and a lot of direct sun. It is hardy to -10F or -23C. Variety jaegeriana seems to be a somewhat smaller version, but how exactly it differs is unclear.

Yucca decipiens (Palma China) This is a rare species in cultivation, originating from Mexico, and is very similar to Yucca filifera in shape and habit. It develops a massively wide base over time and eventually branches. Leaves are stiff and dangerously sharp. Flowers are upright rather than pendulous, though, and that is about the only way I can tell this one from Yucca filifera. Cold hardiness is to about 15F or -9C.

Yucca decipiens

Yucca desmetiana. This is not a common species of Yucca in cultivation, and it is unknown (as far as I know) in the wild, making it a likely hybrid, though between what and what I have no idea (this species looks like no other Yuccas). It is a non-branching, rubbery-leaved plant with blue-green, short harmless arching leaves that turn a nice burgundy color in winters. It is not very cold hardy having trouble with temperatures below 25F or -4C.

Yucca elata (Soaptree Yucca) This southwest U.S. and Mexican native is one of my favorite species for landscape use. It is a short tree Yucca with a reliable branching habit with multiple heads of thin, pale green leaves with distinctive fibers along their margins. The leaves have sharp tips but are fairly flexible and not terribly dangerous (watch your eyes, though). It has cold hardiness down to about zone 6a (-10F or -23C). This plant needs very well draining soil and full sun.

Yucca endlichiana. This is sort of an oddball Mexican species and one of my favorite Yuccas in my garden. It is a very slow-growing species with turquoise, stiff curved, grooved leaves that arise off a caudiciform base. Though not a great landscape plant except in small, open gardens, it makes a good, though peculiar, potted plant. Flowers are also very un-Yucca like being a bright red-orange. It is cold hardy only down to about 25F or -4C.

Yucca faxoniana (syn. Yucca carnerosana; Eve’s Needle or Giant Spanish Dagger) This Texas/Mexcian species is probably one of the most dangerous Yuccas having very long, rigid and very sharp deep green leaves. It is an excellent and highly ornamental landscape plant however and deserves to be grown more often in areas where it can be given more room. This is a single stemmed Yucca up to 15 feet tall. Cold hardiness is about to zone 8a (10F or -12C).

Yucca filamentosa (Adam’s Needle, Bear Grass or Spoonleaf Yucca) This is another U.S. native (southeast) and is one of the most cold hardy of all the Yuccas. This stemless plant has relatively soft, thin leaves that often bend under their own weight. There is still a sharp tip and the end, but it is not a very dangerous plant as Yuccas go. There are many cultivars of this plant, most variegations and far more popular in cultivation than the normal green form. For more information see this Floridata webpage.

Yucca filifera (Tree Yucca or Peter-pan Palm) This Mexican species has to be the biggest of all the Yuccas growing as tall as fifty feet with massive bases 15 feet wide or more (like a Yucca brevifolia on steroids). Leaves are a deep, dull green and much longer and wider than those of Yucca brevifolia. Despite its amazing landscape potential, it is not (yet) a very popular species. It is relatively cold sensitive only surviving temperatures down to about 10F or -12C (zone 8b).

Yucca glauca (Soap Weed, Bear Grass or Great Plains Yucca) This small, stemless or short-stemmed, wispy to spiny plant is a cold hardy native of the Midwestern U.S., and was one of the banes of my youthful hiking experiences (along with Yucca harrimaniae and a variety of Opuntia spp.). This is the semi-official state flower of New Mexico (along with Yucca elata, since no species was specified in the Yucca’s becoming of the state flower Some varieties are somewhat soft and have relatively harmless leaves while others have dagger-like, stiff and incredibly sharp blades. This is probably the hardiest of the Yuccas, growing happily in the snow-covered Rocky Mountains where temperatures dip down to -30F or -34C.

Yucca glaucas (second photo mambrose and third photo Joan)

Yucca gloriosa (Spanish Dagger, Palm Lily or Mound-Lily Yucca) This southeast U.S. native is another popular species in cultivation (both variegated and non-variegated forms) as it forms relatively short mounds (up to eight feet tall, but usually shorter) of densely leaved globes of rough-surfaced, wide leave blades. The tips are sharp but not very dangerously so. This is a USDA zone 7 to 11 plant and another species that is very tolerant of soil varieties and light availability. However, it does best in full sun and sandy, well draining soils. For more information, see this Floridata webpage.

Yucca grandiflora (Large Flowered Yucca) A tall, suckering Mexican species, this is another relatively uncommon plant in cultivation, partly because it takes up a lot of room and has a lot less adaptable nature compared to the somewhat similar species, Yucca guatamalensis (see below). Leaves are straight, not floppy, and end in a sharp spine. Plants grow as tall as 30 feet, and can grow nearly as wide eventually. Hardiness is down to about zone 9a (20F or -7C).

Yucca grandifloras in Huntington Gardens

Yucca guatemalensis (syn. Y. elephantipes; Spineless, Blue-Stem or Giant Yucca) This Central American Yucca is the most commonly grown Yucca in Southern California where it is virtually ubiquitous in most urban and rural areas as popular landscape trees. Though not very cold tolerant, it is at least one of the most versatile Yuccas in warmer climates tolerating a wide variety of soil types, sun exposures and humidity (will grow well in humid climates, as well as being quite drought tolerant). It is even useful as a house plant and rivals some of the Cordylines and Dracaenas as one of the most commonly grown palm-like house plants in the U.S. Large plants can grow up to thirty feet and have massive bases with dozens of stems. It is a variable species, at least now in cultivation where many plants are possibly hybrids with something else. It has long, rubbery leave blades with only mildly sharp tips. A variegated form is sometimes seen.

Yucca harrimaniae (Spanish Bayonet or New Mexico Yucca) Even more than Yucca glauca, this plant was an annoying presence in my years growing up in New Mexico, constantly poking through my pants, shoes and socks as I hiked about the countryside. My neighbor’s sister lost an eye to this plant. But now that I have more of an appreciation for sharp and dangerous things, I find it at least somewhat ornamental. It is a stemless, neat, compact species about 2 feet tall and wide. It is extremely drought-tolerant and survives temperatures down to about -20F or -30C, but seems somewhat intolerant of climates that stay too warm, making it a hard plant to keep alive in my southern California climate.

Yucca harrimaniaes (var. neomexicana in second photo)

Yucca nana (Dwarf Yucca) still uncommon in cultivation, this Utah native is one of the smallest Yuccas only growing about six to eight inches tall and wide. It has a neat habit, though, and makes a nice potted plant or accent for smaller landscape areas. I sometime have a hard time telling this from a few species of Agave, though their flowers look nothing alike. It is cold hardy down to about -20F or -29C.

Yucca nana

Yucca recurvifolia (Curve-leaf or Pendulous Yucca) This Southeast U.S. native is one of the popular Yuccas in cultivation since it is common, relatively ‘safe’ and comes in a variety of tropical looking cultivars. This plant eventually forms a short unbranched (usually) trunk up to six feet. Hardiness is about 0F or -18C.

Yucca recurvifolias (first photo ptyler); second photo var. ‘Margaritaville’

Yucca rigida (Blue or Silver-leaf Yucca) This Mexican species is one of the most beautiful of all the stemmed Yuccas having very stiff, sharp pale blue to blue-green leaves. Sometimes confused with Yucca rostrata, one can easily tell the difference up close by feeling the leaf blades- very stiff ending in an extremely sharp tip. This plant grows up to over ten feet and can either have many heads or just one to two. This species does not tolerate low light situations well and will usually start growing abnormally short, stunted leaves in shade. It is cold tolerant to about zone 7b (5F or -15C).

Yucca rigidas (last photo seedling in my garden)

Yucca rostrata (Beaked Yucca) This is a Texan and Mexican native that is well known for its ornamental appearance. It is one of the most popular specimen Yuccas in Southern California thanks to the striking blue sphere of flat, subtly variegated leaves. Though the leaves have sharp tips, they are flexible and not one of the more dangerous Yuccas. Yucca rostrata is an easy species to grow with minimal care (as are most Yuccas) and can remain in a pot for many years, growing up to ten feet tall or more. Most plants seem to remain solitary, but some branch after flowering creating a fantastic two to three headed beauty. This is pretty cold tolerant plant surviving zone 5b (-15F or -26C). For more information, see this webpage.

Yucca schidigera (Mojave Yucca) Native to the deserts of Southern California along with several other southwestern states and Baja California, this common, medium-stemmed (up to 15 feet tall eventually) Yucca is one of the least-used Yuccas in landscaping, partly due to its dagger-like leaves but also because of its somewhat unkempt and less-than-ornamental appeal. Despite this lack of landscape use, it is one of the more used species in herbal medicines. This plant is cold hardy down to about 20F or -7C.

Yucca schidigeras in native landscape, southern California

Yucca schottii (Mountain Yucca) This Southwest U.S. native is a short-stemmed Yucca (it can grow up to 20 feet tall eventually, though) with very stiff and straight leaves. Though it is used in landscaping in some southwestern climates, it is not one of the more ornamental of the Yuccas having a relatively sparse head of leaves. It is a natural hybrid between Yucca baccata and Yucca elata. Cold hardiness is fairly good, down to -10F or -23C.

Yucca thompsoniana (Thompson’s Yucca or Beaked Yucca) This Texan native can sometimes be confused with Yucca rostrata having a densely leaved globe of pale bluish to blue-green leaves. However this species has slightly stiffer, rougher leaves and is a reliable branch-former growing into small, ornamental trees about eight to ten feet tall and up to ten branches. Older plants can look a bit like the smaller form of Yucca brevifolia, but the branches are shorter and crowns bluer. This plant is cold hardy down to about 5F or -15C.

Yucca thompsonianas

Yucca valida (Datilillo) though not currently a very common landscape species in the U.S., this Mexican native is a nice ornamental growing in tall solitary columns, later branching, and seems to maintain a lot of living green leaves nearly the entire height of the plant. These leaves are relatively short, stout, stiff and ‘agave-like’, ending in a very sharp thorn. It is one of the less hardy Yuccas surviving only down to zone 9a (20F or -6C).

Yucca vallida

Yucca whipplei (aka Hesperoyucca; Chaparral Yucca or Our Lord’s Candle) This is a native from Baja California and is one of the few monocarpic Yuccas. However, it goes out with a bang, producing a huge panicle up to 20 feet tall. The flower begins as a brilliant red spike which is in striking contrast to the bright turquoise to pale green leaves. This a stemless species with particularly spiny, stiff leaves so it is not a good landscape plant near foot traffic. Cold hardiness is down to about 10F or -23C. Recently some have put this in its own genus, Hesperoyucca.

If you love to have a tropical garden like setup and you live in a cold climate then grow these cold hardy tropical plants to create a tropical garden in a cold climate.

The best thing about the plants we’ve listed here is that most of them can be grown in containers too.

Cold Hardy Tropical Plants

Bamboos

bamboos in tropical garden

Bamboos grow best in warm tropical climate but there are many cold hardy varieties available that you can try under USDA Zones 5-9. To find out the cultivars check out this post on Gardening Know How.

Colocasia

Colocasia “Pink China” is one of the hardiest varieties. You can grow it in cold climate down to USDA zones 7 and even zone 6 outdoors on the ground. On the onset of winter mulch heavily with organic matter around the roots of the plant and keep the soil little dry to overwinter it.

Hibiscus

The reason behind the popularity of hibiscus is they are easy to grow and successfully thrive not only in tropics but also in cooler regions. Cold hardy hibiscus hybrids are grown as far north as zone 4. American Meadows has hibiscus varieties for you.

Bird of Paradise

Grow giant bird of paradise (Strelitzia Nicolai) to add drama to your garden. It will give you a real tropical feel. However, bird of paradise grows best in subtropical and tropical climate (USDA Zones 9-11) and you’ll need to grow it in a pot if you live in a temperate region.

Palms

palms in tropical garden

Needle palm, windmill palm, sago palm are grown in cold climates. Here’s a list of hardiest palms to check.

Canna

Canna can be grown in pots and on the ground easily. Probably they are one of the easiest tropical plants that you can grow. Growing canna will provide you a great foliage show and gaudy flowers and to get that all you have to do is to mulch heavily around the base in winter. You can try growing canna down to USDA Zone 6.

Hardy Banana (Musa basjoo)

Banana trees add a tropical touch to any garden. You can even grow them in containers. This cold hardy banana cultivar called “Musa basjoo” can be grown in USDA Zones 5-11.

Hostas

Hostas are great groundcover with the foliage that comes in a variety of shades, they look nice. Grow them in USDA Zones 3-10 in shade or partial shade and provide regular watering.

Ferns

Ferns can be a great addition to your garden to give it a tropical look. Some of the most cold hardy ferns that you can grow are Western maidenhair fern, Lady fern, Christmas fern, Western sword fern, and Common polypody.

Agapanthus

A beautiful and tough herbaceous perennial that grows in tropics and can be grown in temperates too. Introduce agapanthus in your garden to add a touch of blue-violet flowers and lush strap-like foliage. It is suitable for containers and borders.

Bougainvillea

Bougainvillea is a very common plant in tropics. It is a sturdy perennial with lovely paper like flowers. However, bougainvillea is not as cold hardy as agapanthus but you can grow it in containers and move it inside in winters.

Yucca

Beaked Yucca (Yucca Rostrata) is the best cold hardy yucca that you can grow outside in cold climates. It grows well in USDA Zones 5-11. To overwinter it, protection from moisture must be provided in the winters in the cooler zones.

Mandevilla

In tropics, flowering vines grow in abundance. Bougainvillea, passiflora, Mandevilla, jasmine are a few names. Mandevilla is definitely not a cold hardy plant but you can overwinter it indoors by growing it in the container.

Japanese silver grass

Japanese silver grass grows well in cool temperate regions in USDA zones 5-9. It is a tropical looking plant that can be a wonderful addition to your garden.
