Zone 5 Succulents: Tips On Growing Succulents In Zone 5

Succulentsare a diverse group of plants found throughout the globe. They are often considered desert denizens, but these plants also have remarkable cold tolerance and can perform beautifully in many environmental settings. Zone 5 succulents have to withstand temperatures of -20 to -10 degrees Fahrenheit (-29 to -23 C.). Growing succulents in zone 5 requires carefully choosing the right species with a tolerance of these potential cold temperatures. This article will help.

What are Hardy Succulent Plants?

Hardy succulent plants may seem an impossibility if you consider them just warm region flora. Look outside the box and consider that some succulents actually survive in chilly alpine climates and thrive in areas where freezes are potential. Many succulents for zone 5 are available as long as you consider their hardiness range. When you purchase your plants, check the tags or ask nursery professionals to determine whether they are right for your United States Department of Agriculture zone.

Hardiness is determined by a plant’s ability to withstand certain temperatures and weather conditions. The United States Department of Agriculture has a handy map outlining the climates and microclimates of the

United States, and the UK and other European regions have similar maps in Celsius. These are excellent references when choosing plants and help determine the specimen’s fitness to withstand the climate in which they will be planted.

Many succulents are remarkably adaptable in colder regions because their native range experiences similar weather challenges. The key is to find succulents for zone 5 that are adaptable to your specific zone.

Growing Succulents in Zone 5

Zone 5 regions run from the middle of the United States, east to New England and west to parts of Idaho. These are chilly areas in winter, and succulents have to be able to withstand freezing temperatures of at least -10 degrees Fahrenheit (-23 C.) during the winter. In summers, the heat ranges vary, but most plants are perfectly happy in any warm temperatures they can experience. However, the freezing temperature determines if a plant can survive over the winter and is crucial unless you are bringing plants indoors for the cold season.

Many plants that might be marginally hardy can survive with heavy mulching to protect the root zone or even by carefully covering the plant to help protect it from ice and snow. Zone 5 succulents, such as classic hens and chicks (Sempervivum) and bold yucca, will still survive that region’s winter and explode with beauty in spring. Growing succulents in zone 5 that are marginally hardy can also be done by planting in microclimates and protected areas of the garden.

Types of Succulents for Zone 5

Many succulents are so adaptable that they can grow in zones from 4 to 9. These tough plants only require well-draining soil and spring and summer sunshine to thrive. Some examples of zone 5 plants include:

  • Agave (several species)
  • Thompson’s or Red Yucca
  • Myrtle Spurge
  • Stonecrop (and many other species of Sedum)
  • Opuntia ‘ Compressa’
  • Jovibarba (Beard of Jupiter)
  • Ice Plant
  • Orostachys ‘Dunce Cap’
  • Othonna ‘Little Pickles’
  • Rosularia muratdaghensis
  • Sempervivum
  • Portulaca
  • Opuntia humifusa

Have fun and mix up these tough succulents. Intermingling them with grasses and other perennial plants can create quite a year around spectacle with no worries that your succulents won’t survive the next harsh winter.

There are some general guidelines you should follow for succulents. Here are a few:

– Allow your plants to dry out before watering. About the only mistake you can make with succulents is over watering!

– It’s perfectly o.k. to trim and prune succulents to maintain their shape and keep them looking their best. Don’t fret about trimming too much or damaging the plant – the choices above are the ultimate in hardy.

– Succulents love sunshine, so always do your best to plant them in sunny locations …

– In terms of soil, succulents do best in well draining soil. If you’re creating your own potting mix, go for equal parts of potting soil, pea gravel, and sand.

Flower Chick

Helping gardeners in Zone 5b (west suburban Chicago area) for over 30 years! During that time I’ve become a “go to” person among friends and family for practical, straightforward gardening advice. A long time friend dubbed me “Flower Chick” many years ago and the nickname stuck!

Succulents, with their interesting shapes and colors, have become increasingly popular in the landscape. While larger succulents are often used singly as accent or container plants, smaller succulents are getting a second look for use as ground covers. As with other succulents, they are attractive, drought-tolerant and low-maintenance. Here are 8 low-growing succulents for you to try in your garden.

It’s important to note that all plants profiled below require well-drained soil and, in many cases, some supplemental watering. The amount and frequency of watering depend on several variables, including exposure, temperature and soil. A good rule of thumb is to water 8 inches deep and then allow the soil to dry out before watering again. Succulents need more water in spring, when they are actively growing, and very little in winter.

1. Rock Purslane
(Calandrinia spectabilis)

Gray-green leaves form a dense mound that is transformed by the appearance of magenta flowers spring through fall. The flowers are about 2 inches wide and last one day, with new ones ready to take their place the following day.

For an eye-catching combination, pair rock purslane with pig’s ear (Cotyledon orbiculata), a succulent that produces orange flowers. Rock purslane does best in Mediterranean climates but is suitable as a container plant and can be treated as an annual in colder climates.

Origin: Chile
Where it will grow: Hardy to 20 degrees Fahrenheit, or minus 6.7 degrees Celsius (USDA Zone 9)
Water requirement: Low
Light requirement: Full sun or filtered shade
Mature size: 1 foot tall and 3 feet wide; about 3 feet tall when in flower

2. Caucasian Stonecrop
(Sedum spurium)

Succulents aren’t just for warm climates. This creeping ground cover can grow in zones 3 to 8. The beauty of this species of stonecrop lies in its tightly whorled leaves, which are often tinged in red. In late spring and summer, star-shaped pink flowers blanket the leaves and attract butterflies.

S. spurium ‘Red Carpet’ grows in the foreground of this photo, with blue-gray S. reflexum ‘Blue Spruce’ in the background.

Origin: Caucasus region of Eastern Europe
Where it will grow: Hardy to minus 40 degrees Fahrenheit, or minus 40 degrees Celsius (zones 3 to 8)
Water requirement: Low
Light requirement: Full sun
Mature size: 3 to 6 inches tall and 1 foot to 2 feet wide

3. Blue Chalksticks
(Senecio serpens)

The lovely blue-gray and upright 1-inch leaves gradually spread to create an attractive ground cover in frost-free areas. The flowers range from white to chartreuse and appear in summer. Blue chalksticks is ideal for creating color contrast when used next to plants with bright green foliage, such as kangaroo paw (Anigozanthos spp.). It’s a good choice for areas with mild Mediterranean climates. In addition to making a great ground cover, this beauty is often used for erosion control, in containers and as a fire-wise plant.

Here, blue chalksticks grow between Furcraea macdougalii in the background and ‘Elijah Blue’ blue fescue (Festuca glauca ‘Elijah Blue’) in the foreground.

Origin: South Africa
Where it will grow: Hardy to 20 Fahrenheit, or minus 6.7 degrees Celsius (Zone 9)
Water requirement: Low
Light requirement: Full sun or filtered shade
Mature size: 1 foot tall and 2 to 3 feet wide

4. Parry’s Agave
(Agave parryi)

Small- to medium-size agave species are unconventional ground cover choices that are becoming more popular. For example, Parry’s agave, with its very attractive rosette pattern, makes a wonderful water-wise ground cover. Use it next to boulders for great texture contrast. This plant and other smaller agave species work well in arid climates, including low-desert climates, since they can handle the full sun and intense summer heat that may cause succulents better suited for mild Mediterranean climates to struggle.

In this photo, A. parryi var. truncata grows among larger species of agave.

Origin: American Southwest and Mexico
Where it will grow: Hardy to minus 10 to 20 degrees Fahrenheit, or minus 23.3 to 6.7 degrees Celsius (zones 5 to 9, depending on variety)
Water requirement: Low
Light requirement: Full sun or filtered shade
Mature size: 1 foot to 3 feet tall and wide

5. Upright Myrtle Spurge
(Euphorbia rigida)

Chartreuse flowers, which gradually turn green and then tan, provide welcome color to drought-tolerant landscapes from late winter into spring. The pointed blue-gray leaves are arranged in spirals, which offer decorative texture throughout the year. Upright myrtle spurge can handle temperatures from over 100 degrees Fahrenheit (37.8 degrees Celsius) all the way down to minus 20 degrees Fahrenheit (minus 28.9 degrees Celsius). Plant in groups of three or five alongside boulders and flowering perennials like beardtongue (Penstemon spp.)

Origin: Mediterranean region
Where it will grow: Hardy to minus 20 degrees Fahrenheit, or minus 28.9 degrees Celsius (Zone 5)
Water requirement: Low
Light requirement: Full sun or filtered shade
Mature size: 2 feet tall and 3 feet wide

6. Resin Spurge
(Euphorbia resinifera)

Square light-green stems arranged in clumps give this African native the appearance of a cactus. The sides of the stems are covered in brown spines. Older specimens can grow quite large and look at home next to columnar cactuses. Smaller ones look great next to boulders and drought-tolerant perennials such as desert marigold (Baileya multiradiata) and blackfoot daisy (Melampodium leucanthum).

Here, resin spurge surrounds a Peruvian apple cactus (Cereus repandus), along with soap aloe (Aloe maculata) and its colorful flowers.

Caution: The milky sap is toxic.

Origin: Morocco
Where it will grow: Hardy to 20 degrees Fahrenheit, or minus 6.7 degrees Celsius (Zone 9)
Water requirement: Low
Light requirement: Full sun; can take afternoon shade in low desert
Mature size: 2 to 3 feet tall and 3 to 5 feet wide

7. Royal Dewflower
(Drosanthemum speciosum)

Vibrant flowers in shades of pink, purple and red, depending on the variety, create a colorful carpet in late spring into summer, almost completely covering the foliage. When this succulent with purple flowers is not in flower, the narrow gray-green leaves add a visually cooling element to the garden. Royal dewflower roots when it comes into contact with bare soil, helping it to spread up to 3 feet wide. Although its low growth habit may lure you to walk on it, avoid the temptation since it doesn’t tolerate foot traffic. If you’re looking for a succulent with purple flowers, this is it!

Here, D. speciosum ‘Rosea’ covers a gentle slope.

Origin: South Africa
Where it will grow: Hardy to 20 degrees Fahrenheit, or minus 6.7 degrees Celsius (Zone 9)
Water requirement: Low
Light requirement: Full sun; part shade in the desert
Mature size: 6 to 12 inches tall and 3 feet wide

8. Candelilla
(Euphorbia antisyphilitica)

Narrow, waxy stems, with an upright growth habit, add another dimension to the landscape. Rather than spreading outward close to the ground, new stems are produced along the outer part of the plant, gradually increasing its width while still growing upright. Tiny pale pink flowers bloom along the upper half of the stems in spring. Small leaves may appear and are soon shed. Create a visually appealing design by planting candelilla in staggered rows.

Origin: New Mexico, southwestern Texas and Mexico
Where it will grow: Hardy to 10 degrees Fahrenheit, or minus 12.2 degrees Celsius (Zone 8)
Water requirement: Low
Light requirement: Full, reflected sun
Mature size: 1 foot to 2 feet tall and 2 to 3 feet wide
