I live in Northern Canada, so this plant will never become invasive - it cannot survive our winters outdoors. So, I plant it in pots and sink the pots into the ground and lift them or plant the bulbs right into the ground and dig them up in the fall. 3 years ago I decided to bring a pot into the house and not directly into a cold storage area, after it had died off with the first hard killing frost, and it started to grow..It has thrived ever since, so now in addition to having this beauty outside, its in my house and I love it!

I live in north east NEBR. and have the plants on the north side of the house next to the foundation. Sometimes, I dig up the small corms in the fall, put them in the basement to keep dark and cool, then start them in 6 packs. Other times, I usually just let the frost get them in the fall, but they usually come back again when the ground warms up in the spring. They are prolific little dudes! And there usually are many corms. I haven't tried to transplant them--never had to do that; they have their own special place.

I cant get it to do much more then survive with a few sprigs...then dies off in winter here warm or cold. Last year it waited until mid summer to send up a few leaves.
Maybe it needs a really cold winter,or full sun here.That's a possibility as I had planted it in light shade under a King palm and with some Adiantum ferns.
It hasn't looked like the day I bought it,since the day I bought it. Still alive though...I think.
Wouldn't you know it,I badmouth the plant,and now I see its popped out of the ground under King palms. Yet,I'm not sure if it would do better with much more sun then the light shade it gets under the palms and near the shade of my house.

This has been a great houseplant for me. If you forget to water, it will go dormant. When watered, it sends up new foliage. A very forgiving plant. Very low light requirement.

This plant does not seem to require a dormant period. I have a friend who for years has summered them outdoors and then kept them going all winter indoors as a houseplant, with never a rest.

I've tried to grow this as a hardy perennial in Boston Z6a, and though it managed to survive its first winter, it only sent up a few leaves its second season, and didn't survive its second winter. Perhaps it's just as well, given its invasive proclivities.

I have tried growing this plant here in Louisiana a number of times, and of all those that I have planted only one has survived, and barely at that. On the other hand, the green oxalis that grows here (one variety with pink blossoms, the other with raspberry-colored ones), is so hardy and invasive that it completely covers the lawns of some homeowners, and it pops up everywhere, often in unwanted places, alas. It can easily be killed with herbicide, but when it grows in and around other desirable plants that is not feasible. The only alternative is to dig them out, but that is usually not a long-term solution, as they tend to come back from the numerous bulbs they propduce. I used to think it was pretty until it took over. Now, it is the bane of my gardening existence. I doubt that t... read more

I live in Adelaide, South Australia, which is hot and dry in summer, with reasonable winter rain. I was horrified when I saw this plant advocated as something people would actually try to grow. I spent at least 20 years trying to eradicate it from a long driveway where it never received water other than winter rain, and the soil was dry and poor. It was only dealt with when the driveway was dug out mechanically to replace the underground sewer pipes, and the top two feet of soil were removed. A pest plant in my, and most Australians', opinion.

It flowers off and on all year.

Only problem it ever has is spider mites.

Houseplant care: Keep moist. Drain after every watering. Slightly cover bulbs/corms with soil. Choose a deep enough pot for root growth. They like space to spread out & semi-shade/med light. Will go dormant if temp goes below 70F/22C.

Has been the envy of the office. I take it home & hide it when it takes its annual Feb-June nap. Have relatives who plant outside & re-dig every yr. Theirs look a bit healthier, but they have to keep getting bigger flower pots & find places to put the much bigger plants. Mine looks pretty enough.

For me and my Mom, when I was a kid, this was a plant that grew in the shady woods. There were two slightly different varieties and she called the one with pink flowers, Sheep Showers. This one she said we could eat. And we did, or at least I did...always raw. I'd pull the leaves and flowers off and eat them on the spot. Nice lemony tartness.

The smaller leafed one of the two had yellow blooms, and she called this one Snake Showers. She said this one was poison, but I ate it anyway...never any problems. There never was very many of these plants in the woods, and none of my siblings chose to sample. I called it my spring tonic.

I received this plant in bulbs from Richard Owens Nursery for buying other items, it was a freebee, and it grew like crazy. Mine have green four leaf clover leaves with purple on the inside, then a cute little pink flower came up from within, very pretty. I was given four bulbs and all four bloomed, I gave two away and kept two for myself; but they were not all purple like in the picture in this article, only in the inside of the leaf the outside was green which I think, looked really nice.

First of all -- this is a fantastic and gorgeous plant! In Georgia, it grows all year round and flowers too! How many plants do that, huh?! Second, it is VERY invasive from seed. Third, it is interesting for the kiddies...it is sensitive to touch and will fold its leaves downward when touched by rain and other -- as it does in the evening. The beauty is the fact that, although it's invasive, it's worth the trouble for its hearty growth and cheerful visage.

After this oxalis had gotten leggy and it was long after St Patrick's Day, I planted it in the ground, under an old pieris japonica.

About 3 years ago I added the green Shamrock to the bed & last year I added a new one I had never seen before. It has green leaves with the deep burgundy in the center.

On the south side of Chicago, the area grocery stores sell these right around the time of the South Side Irish Parade in March. I got the purple triangularis one and also a green one, oxalis acetosella that has white flowers. Not sure if it's true, but someone told me that this plant naturally goes dormant for a month after about 3 months looking good. You are supposed to just leave it alone while it looks dead for 4 weeks then it suddenly comes back to life. I have mine in diluted light and every morning, there it is all puffed up and beautiful ready to start my day. Every night when I come home from work there it is, sleeping with the leaves all collapsed and snuggled.

The first time I planted this, it was in a hanging basket with some morning glory vines. Neither liked the full sun or windy location. The morning glories died within days, and the Oxalis started to lose its purple colour and revert to green. Despite some dieback, it survived and I surrounded it with some supertunias which shielded it from the sun and wind. Once fertilized, it really took off and flowered.

Next I tried it in a shaded location in a container with lobelia and fuchsia. It did marvellously and looked beautiful. I've learned now that it works best in shade or part sun instead of full sun.

I originally bought these as a houseplant several years ago. It would continuously send up new leaves, and flower every few months. I kept it near a bright window, and only added houseplant fertilizer once in a while. The leaves and flowers wilt and fade, so there is a little cleanup required to keep it tidy. The only other care I gave it, besides water, was to rotate the pot, as the leaves will lean towards the light. It performed nonstop for at least 5 years, before the bulbs started to die off, one by one. Very fun plant to add a little different color in the houseplant collection.

I am curious about propagation of this plant. I generally propagate this plant by splitting the rhizomes but have noticed lately that a lone plant will sprout 6-8 feet away from a bed of these plants. There is no evidence of any other oxalis between the bed and the sprout. How does it travel this relatively great distance? It is a beautiful and forgiving plant I have had almost 15 years now, splitting and sharing every opportunity that arises. Especially beautiful when mixed with the all green oxalis/white flower.

For those of you 'zone challenged' gardeners it
(and most tender Ox)
are very good container plants that winter well.

Bring in before the first frost.
Enjoy in a sunny window for a while.
Then allow them to go dormant by not watering at all.
After the foliage has died off wait a few weeks to a few months and dig up the corms.

Replant in average soil to about the depth of the corm (1/4 -1/2" deep) and water well.
We go about 2" between corms.

In a week or so they will start to break ground.

While it is easy to over-winter Oxalis as a plant the dormancy is crucial for new and lush blooms.
This is especially true of the purple forms.

San Antonio, Texas
This plant does well planted where it receives morning sun and afternoon shade or filtered shade in my area. Compared to the pink oxalis I have planted, it withstands the summer heat better and is bloomimg profusely after 108 degree weather. If it dies down during extreme heat when it is planted in a more sunny location, it will rebound when temperatures become cooler. Mine continue to bloom until the first frost. It's deep rich purple leaves provide outstanding foreground color against green background plantings. No insect pests have attacked it, but field rats ate several plants I had in pots on my patio to the ground in May. They resprouted at the end of July.

We are now into the later part of July (getting into 100F degree weather daily) and the thing is blooming like mad and putting on new leaves everyday.

The purple leaves can last for weeks in water as long as you immerse them as soon as they are cut.

Plant in light shade. Too much sun makes for poor growth. Too much shade slows growth and gives the leaves a greenish tint.

If there are multiple growing points, propagation can be by division of the root/corm. If there is only one growing point you can break the corm into two but the piece without a growing point may or may not grow - just plant it and forget it.

Plant propagates by corms/splitting. It can also root in water.
