Care instructions for Oxalis triangularis: Grow in rich, well-drained potting soil, and water when the top inch of soil feels dry to maintain a healthy Purple Shamrock plant. Keep indoor temperatures between 60 and 75 degrees Fahrenheit, fertilize every two to three weeks, place in bright light.
Does purple shamrock grow indoors?
Oxalis triangularis, often known as the purple-leaf shamrock, is a low-growing foliage plant for the garden that also makes a lovely indoor plant with lush, vivid purple leaves. For decades, savvy gardeners have turned to this lovely foliage plant to bring color both inside and outside.
This 1980s import from Brazil has become more popular in the United States. It can fill a container with deep purple foliage inside and inject some color into the typically green interior plant world. It is essentially a collection of miniature plants that emerge from bulbs. It has very few requirements, however excessively moist soils are something it cannot stand. The plant must be kept in a container with a drainage hole and must not be overwatered. This shamrock may wilt and become dormant if exposed to temperatures higher than 80 degrees. Calls are made to Michigan State University Extension horticulture educators and hotlines regarding the inexplicable death of a once-healthy shamrock.
Purple shamrocks are planted outside in partially shaded regions. They aren’t much taller than 6 inches, so they need to be at the head of the bed or in a container that needs year-round color to be seen. The shamrock produces tiny, pale pink, bell-shaped flowers when the climate is mild and there is enough rain. The joyful shamrocks will have multiplied by autumn. It’s time to make the crucial choice now. They can be dug up, placed in a pot, and used as an indoor plant over the winter, or they can be stored like other summer bulbs and brought back to life in the spring.
Dig the plant in mid-September before any frosts if the shamrock will be grown inside. Thus, the foliage maintains its excellent looks. To settle the soil, place it in a container with a drain hole and give it a good watering. Place the shamrock in a bright window after it is inside. Since some of the light is filtered by the windows and the days are getting shorter, the plant can tolerate more sunlight indoors. South, west, and east are the windows that often receive the most sunlight; avoid the north because there may be no sunlight at all.
If the bulbs are going to be stored for the winter, carefully remove as much soil as you can from the chunks of closely packed bulbs and roots by digging. Until the foliage dies down and dries up, place inside a cardboard box and bring inside. Pips, or miniature bulbs, are also known as short, fat, carrot-shaped tubers, which are typically found on larger plants that had a prosperous growing season. Cut the plant off just below the soil’s surface once the foliage has dried up. It can take a week or so to complete. Bulb clusters should be kept dry and nestled into a bed of vermiculite, dry sphagnum peat moss, Canadian peat, or wood shavings in a container such as a cardboard box or paper bag. The peat has the added benefit of being acidic, which stops any rots before they ever begin. A buffer of packing material should be placed under, around, and around root clumps. This will delay the bulbs’ drying process. Place the container in a place that will be dark and have a temperature of 40 to 50 degrees. They remain inactive in cool, dark environments. Freezing kills.
Plant the stored clumps approximately 1 inch beneath the soil and give them plenty of water in the spring when all risk of frost has passed, which is often between the middle and late of May. The new growth won’t start for four to six weeks. You can remove your indoor shamrock from its pot so it can grow wild once more.
How much sun is required for a purple shamrock?
Light. This plant thrives in full sun to light shade, which corresponds to four hours of direct sunshine on the majority of days. Give it some cover from the intense afternoon light if you’re growing it outside and live in a warm climate. The plant should be cultivated close to a window that receives plenty of natural light indoors.
How often should purple shamrock be watered?

The oxalis triangularis comes first. Don’t be too quick to judge all kinds of oxalis by the poor conduct of a few relatives, though! The oxalis family is broad and diverse, including several rampantly invasive types that have earned oxalis a bad reputation as “garden thugs.” Many oxalis species are completely obedient and make lovely additions to your house and yard. Two types, oxalis triangularis and regnelli, are suitable for growing inside as long-lived houseplants and are hardy in all American climes. Both can survive outside in zones 6 to 11, but they adapt easily to indoor environments and flourish well there all year. Let’s take a closer look at oxalis triangularis with its creative and interesting purple foliage.
Oxalis Triangularis Origins
“Purple shamrocks” are another name for oxalis triangularis.

How are indoor shamrock plants cared for?
- Place the plant in a location that is at room temperature, has sufficient airflow, and receives bright but indirect light.
- Keep the soil just slightly damp. Use little water and let the soil dry up in between applications.
- Every few months, fertilize indoor plants with a balanced fertilizer.
- The plant is signaling to you that it needs a period of dormancy to rest when its leaves start to die back in late spring or early summer. Do not water or fertilize the plant at this time; instead, relocate it to a cooler, darker area away from direct sun. Depending on the cultivar and the environment, the dormant phase might extend anywhere from a few weeks and three months.
- Check your plant for new growth every week or so after the first few weeks of dormancy.
- The time of dormancy is over once new shoots start to develop. Relocate the plant to a more sunny spot and carry on with the suggested routine plant maintenance.

How come my purple shamrock is sagging?
When it comes to Oxalis, three is frequently the magic number. Oxalis triangularis, often known as the “love plant,” “purple shamrock,” and “false shamrock,” is the species that is most frequently grown as a houseplant.
It features three symmetrically arranged purple heart-shaped leaves with three sides each that are arranged on the ends of each petiole (or “stem”). Overall, they have the appearance of three butterflies connected together by their noses.
Other species have a form that is comparable, although their leaves are often green.
The plant’s ability to raise itself from the dead lends it a hint of mysticism as well. Like many other plants, Oxalis is not naturally connected to the earth; rather, it is connected to the soil through its tiny bulbs.
Everything above the surface will wilt and die back to take refuge in the bulbs below if you forget to water it, the temperature gets too low, or its living conditions are generally poor.
When favorable conditions are once again present, the plant revives very quickly. This is fantastic for those tiny mishaps where we may forget to water our indoor plants for a period of time. The plant can be considered a weed in temperate regions of the world, which is not helpful for individuals who live there.
The plant is delicate and petite with lovely leaves, and everything stays compact if kept in a pot, which in many ways makes it the perfect house or office plant.

My shamrock plant is withering; why?
Most of the time, when a shamrock plant looks to be withering, all it really needs is a rest period or an off-season.

What is the lifespan of a shamrock plant?
You’re welcome to take your shamrock on a summer vacation outside in a shaded area. According to Michigan State University Extension, you can either leave it in its pot or plant it in front of a shaded border. Dig up the plant before it freezes and repot it so you can enjoy it as a houseplant all winter. Shamrock plants can remain outside all year in warm regions (USDA Hardiness Zone 8 and warmer).
