Caring For Oxalis Plants Outside: How To Grow Oxalis In The Garden

Oxalis, also known as shamrock or sorrel, is a popular indoor plant around the St. Patrick’s Day holiday. This diminutive little plant is also suitable for growing outdoors with minimal attention, although it may need a little help getting through chilly winters. Read on to learn about growing oxalis outdoors.

How to Grow Oxalis in the Garden

Plant oxalis where the soil is moist and well drained, but never soggy. Slightly acidic soil is best. Additionally, improve soil quality and drainage by digging in a little well-rotted manure or compost before planting.

Oxalis needs a few hours of sunlight every day, but plant in afternoon shade if you live in a hot climate. Oxalis leaves may wilt during hot afternoons, but they usually bounce back when the temperature drops in the evening. Keep in mind that species with darker leaves tolerate more sunlight.

Oxalis Outdoor Care

Oxalis plant care in gardens isn’t too demanding nut may include winter protection in cooler climates.

Provide enough water to keep the soil evenly moist. Beware of overwatering, however, as the bulbs will rot in soggy, waterlogged soil. On the other hand, be careful the soil doesn’t get completely dry, especially during hot weather.

Feed oxalis regularly during the growing season using a liquid fertilizer mixed at half strength.

If you live in a warmer climate, don’t be surprised when your oxalis plant turns brown and drops its leaves in late summer. The plant is going into a period of dormancy. Withhold water during this time and resume when new shoots appear in spring.

Take steps to protect your oxalis plant if you live in a chilly climate. Hardiness varies depending on the species, and some, including purple shamrock (Oxalis triangularis), tolerate winters in USDA plant hardiness zone 6. However, most are frost-tender and won’t survive frosty weather.

One option when caring for oxalis plants in winter is to pot them up before freezing temperatures arrive in fall, then bring indoors to a sunny location.

You can also put the plants in a pot and allow them to go completely dormant, which means no watering. Store in a cool, unheated (but non-freezing) room. Move the oxalis plants to a well-lit location in spring, resume watering, and then move back outdoors when all danger of frost has passed.

Alternatively, dig the bulbs and store them until spring. Gently brush off the excess dirt and place the bulbs loosely into a cardboard box. Bring them into the house until the foliage dries up, which takes about a week. Move the bulbs into a container filled with sphagnum moss, peat moss or sawdust, and store them where it’s dark and cool but not freezing.

Low-Maintenance Houseplants: Oxalis Triangularis

If you don’t possess the greenest of thumbs, don’t worry! There are plenty of low-maintenance houseplants that thrive with just minimal care, and we’re happy to highlight some of them for you.

First up is the oxalis triangularis. The oxalis family is large and varied, including some rampantly invasive varieties than have given oxalis a bad rep as “garden thugs,” but don’t be too quick to judge all varieties by the bad behavior of a few relatives! Many oxalis varieties are entirely well-behaved and a delightful addition to your home and garden. With varieties hardy in all climates in the United States, there are two that are also good choices for growing indoors as long-lived houseplants – oxalis triangularis and regnelli. Though both are hardy outdoors in zones 6-11, they adapt well to indoor conditions and thrive indoors year round. With its fanciful and intriguing purple foliage, let’s take a closer look at oxalis triangularis.

Oxalis Triangularis Origins

Oxalis triangularis are often referred to as “purple shamrocks.” The plant’s history can be traced back to St. Patrick, who held a similar plant and used the three leaves to explain the concept of the Holy Trinity to the Irish. Oxalis triangularis are not Irish natives, however – instead, they hail from Brazil.

Special Traits

Oxalis triangularis are highly “photophilic,” which means that they open and close not just their blooms, but also their leaves in response to light. At night, neatly folded, oxalis triangularis looks like a cluster of little purple butterflies that then open wide to the morning light. Both the vivid purple color of its leaves and this constant slow motion seems to enchant all who grow it – even “non-gardeners” fall in love this charming beauty. To capitalize on its unusual coloring, containers in silver or chartreuse are especially effective.

Incredibly long lived, oxalis triangularis often become “heirloom plants” passed down from generation to generation within a family. We often hear customers’ stories of the plants becoming a cherished family tradition. One customer told us she was enjoying the same bulbs as their great, great-grandmother who harvested them as a child 107 years ago! Since oxalis triangularis are super simple to plant and grow, they are frequently given as gifts. Choose one of our many pre-planted oxalis gifts, or take it easy on your wallet and make a nice gift by planting four triangularis in an empty soup can with the label removed. Once these are growing, the look is wonderful between the metallic can and deep purple foliage! Let the gift recipient know that these plants have the potential to become treasured, living family heirlooms that will last for generations with little care.

Be aware that oxalis triangularis has developed a natural toxicity to protect it from foraging animals. This is a plant that bites back, so take care with pets and small animals.

Basic Care

Oxalis triangularis bulbs look like small, immature pinecones. When planting a container for indoors, go ahead and crowd your bulbs, spacing them just an inch apart for a full look fast. Just poke the bulbs into the soil – any way up is right. Water lightly just once every couple of weeks until new growth appears. In about 6 weeks from planting, your new purple shamrocks will begin to appear, and will fill in to become lush and full soon after. Weekly watering should be light. Too much water will send the plant back into dormancy.

Indoors, keep your oxalis triangularis in a sunny spot. You will find the deep purple foliage really brings out the vibrant green of other plants, and the color contrast makes your other houseplants seem to glow with health.

Please note that oxalis triangularis occasionally go dormant, looking like the entire plant has died. Because this happens generally during the summer every 2-7 years when the plant is indoors, it seems like a serious problem rather than a periodic event. There is no need to toss your beloved triangularis! Simply stop watering and let the soil thoroughly dry. Set the plant aside where it is no longer center stage, but where you will still see it. In a few weeks, you will see a new leaf emerge. That is the time to resume watering. Soon, your purple shamrocks will be lush and full again.

The care and feeding of purple-leaf shamrocks

The purple-leaf shamrock, Oxalis triangularis, is a low-growing foliage plant for the garden that also makes for an attractive indoor plant with rich, vibrant, purple leaves. Smart gardeners have gravitated to this beautiful foliage plant to add color indoors and outdoors for several decades.

This Brazilian native came to the United States in the 1980s and its popularity continues to grow. Indoors, it can fill a pot with rich, purple leaves and add a dash of color to the often green indoor plant world. It is actually multiple small plants that grow as a group from bulbs. It has minimal needs, but one thing it cannot tolerate is overly wet soils. It is critical that the plant is in a container with a drain hole and is not overwatered. If this shamrock is exposed to temperatures above 80 degrees, it can wilt and go dormant. Michigan State University Extension horticulture educators and hotlines receive calls about the mysterious shutdown of a previously vigorous shamrock.

Outside, purple shamrocks are put into areas that are somewhat shaded. Because they are not much taller than 6 inches, they need to be in the front of the bed to be seen, or they could be in a container that needs season-long color. When the weather is warm and there is adequate moisture, the shamrock blooms with small, pale pink, bell-like flowers. By fall, the happy shamrocks will have multiplied themselves. Now, it’s time for the big decision. They can be dug and put into a pot and play the role of an indoor plant during the winter, or it is possible to store them like other summer bulbs in a dormant state and reactivate them in the spring.

If the shamrock is going indoors as a growing plant, dig the plant in mid-September before any frosts. This keeps the foliage looking good. Place into a container with a drain hole and water well to settle the soil. When the shamrock is indoors, place in a sunny window. The plant can handle more sunlight indoors because the windows filter out some of the light, and the days are growing shorter so there is less light intensity. The windows that usually have the most sunlight are, in order, south, west, east and avoid north because there may be none at all.

If the bulbs are going to be stored for the winter, dig chunks of roots and bulbs and gently remove as much soil as possible without having the chunks of tightly packed bulbs break apart. Place into a cardboard box and bring into the house until the foliage dies down and dries up. You can find small bulbs, called pips, or you may find short, fat, carrot-shaped tubers with bigger plants that had a great growing season. Once the foliage has dried up, cut off close to the soil surface. This might take a week or so. Store the clumps of bulbs in a container like a cardboard box or paper bag and nestle them into a bed of dry sphagnum peat moss, Canadian peat, wood shavings or vermiculite. The peat has the extra advantage of being acidic and preventing any rots if they should start. Root clumps should have a buffer of packing material under around and over them. This will slow drying of the bulbs. Place the container somewhere that is going to be dark and the temperature should be between 40 and 50 degrees. Cool and dark conditions keep them dormant. Freezing is fatal.

In the spring when all danger of frost has passed, which is usually from the middle to late May, plant the stored clumps about 1 inch beneath the soil and water well. It will take four to six weeks for the new growth to begin. Your indoor shamrock can be freed from its pot to run wild again.

Oxalis Triangularis

The false shamrock native to Brazil has picked up it’s common name from the Irish shamrock symbol which refers to a triangular three leaved plant or the clover. These are often sold and bought as gift pot plants, especially just before St Patrick’s day.

Two interesting aspects of this plant is it’s photonastic response, which is it’s reaction of opening up its leaves during the day and closing at night. And, the other is that it’s known as an edible plant, although there seems to be a lot of discussion about the amount of oxalic acid having negative effects on humans, so I think would rather stick to vegetables to be safe.

While this page is about growing this plant indoors it’s also possible to grow it outdoors in the correct conditions. Your shamrock grown indoors can enjoy the summer period outdoors; in a cool shaded spot, is best.

Flowering: Lot’s of small trumpet shaped blooms sitting above the leaves appear during spring and summer, which you can expect to last a fair few weeks.

Level of care: Most indoors growers will able to grow the oxalis triangularis with ease, if attention is paid to it’s basic care instructions and they’re aware of it’s dormancy period.

Dormancy Period

Like other bulb type plants the shamrock has a dormancy period – which is it’s time for rest. They can go into dormancy after the spring and summer growing season which is noticeable when the leaves stop opening in daylight and it begins to look like it’s lacking vitality (this can also happen at other times whenever your plant chooses). They can also temporarily go into dormancy if temperatures become too warm (above 80°F – 27°C) or it’s lacking water and the soil becomes dry for a long period.

If the foliage begins to look withered and die off, stop watering and feeding and let the foliage die down. Once the foliage becomes brown you can remove it and await the next growing period, which could be anything from 2 – 4 weeks. Once you see new growth, normal watering and feeding instructions can be provided.
