OXALIS TRIANGULARIS

About Plant

Oxalis triangularis is often referred to as “purple shamrocks.” 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. 
Be aware that oxalis triangularis has developed natural toxicity to protect it from foraging animals. This is a plant that bites back, so take care of 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.
Grow oxalis triangularis for a long-lived, easy-care houseplant with extra charm. Enjoy your purple shamrocks!
