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.
Some I dug up last fall and put into a pot..are still not up in late April. Its touchy..not as easy in California as testimonials from elsewhere make them sound.

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.

Neutral ruprecht On Apr 21, 2014, ruprecht from Shreveport, LA (Zone 8a) wrote:

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 the purple variety will be a nuisance here such as it seems to be in Australia.

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.

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.

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.

I have had my Oxalis for several years, too many to remember. When we moved into a new home (on the same property) in 1994, I moved it, too. Mine is planted in beds on each side of my front steps, in filtered sun. They are thriving very well.
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. It puts out the palest of pale pink flowers, a definite difference to the white & dark pink of the other two. All are doing fine, spreading & thriving.
When I "built" my beds, I put down several layers of newspapers, then about 5 inches of top soil. I have never fertilized my plants.
I tried planting some in another area next to my garage that gets more sunlight, and is "good ol' Alabama red clay", but they did not do as well. They are still there, just do not spread, grow or produce flowers.

Here in Western New York state, I save the oxaxlis roots over winter in newspaper lined flats. Pull them from the garden, shake off most of the dirt, then let the clumps dry before storing. Stack up the flats on shelves in the garage or basement - as long as they don't freeze. Around mid-March, I break up the clumps and set the roots in fresh potting soil. Line an empty flat with landscape fabric that overlaps the edge of the flat by a couple inches, add a couple inches of soil then the roots and cover with more soil. Water the flats and set them under lights. When danger of frost is past, slip the plants out of the flat - using the landscape fabric to pull them out -into a prepared area a little larger than the flat and then backfill with garden soil. I leave the landscape fabric right in place - the roots often go right through and the drainage is great. Makes a nice instant edging. As for the roots, I think the little pink shrimp-like ones produce the plants; I'm not sure of the function of the bigger white fleshy roots that I find every so often, but I throw them in too.

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 purchased more bulbs this year, adding half to the original pot inside, and planting half outside. They did great during the summer, but started losing the purple around mid October (turning more green) I am going to leave the ones outside in the ground, even though they are a little tender for my zone, to see if they can be wintered over with a layer of mulch.

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.

Digging and repotting are not really necessary but are a good way to increase the number of plants.
Believe me after your friends see this plant, especially in flower they WILL want some.

Edited April 30, 2011
After about 10 years of growing and giving away hundreds of these I still swear by the above method of wintering them.
Now I have another method too.
It's hardy in the ground here in Cincinnati.
Just today 15 of them broke ground after being forgotten last Fall.
No special care given but we are in a micro climate that is at least a zone higher than we're reported to be.

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.

The plants came up every year, surviving 6F degree winter temperatures, and snow on the ground for several days.

Just today in the yard of a friend in Zone 8b in north-central Florida I saw a beautiful single specimen of this plant, again growing in dappled shade, and his plant was about three times taller than the height my plants ever achieved in Georgia.

I received my plant as a gift in a pot around 1997. It did not do well in the pot under my patio cover (USDA Zone 7), so I moved it into the yard where it thrived in dappled shade. I didn't really know what I had, so what I've learned has been from trial and error. I found that it could very easily release the bloom and leaf stems if disturbed by even the lightest water force or by digging to separate. It would quickly recover, however, and be blooming again shortly.

I do not fertilize as it seems to not do well afterwards. I leave it in the ground year round and it's back up in the spring and blooms all summer until fall. It has survived ice, snow, temperatures below 0 and above 100F. It's really a wonder plant and I love it. I've dug and shared with friends. It spreads easily but is not invasive. A more enjoyable plant I've never owned. I finally decided to see what I really had when a friend told me that it was Oxalis - I searched quite a bit, but not until this site did I see a picture of what I have. Thanks!

Well after I re-dug it up, rescued all the rhizomes and repotted it, it actually survived to grow back into a beautiful specimen again.

This is one of my favorite plants. I acquired a pot full of this plant in 1995 from a plant laboratory in a college I was attending at the time. They were doing research into the life cycle and behavior of the plant (flowering and the opening and closing of the leaves). I was told that the proper scientific name of the plant was Oxalis triangulasar, although I could be getting that confused with a more common wood sorrel species in this area (New York, U.S.)

Its a highly resilient plant. Twice, the pot was down to one or two sorry looking individuals (they always sprout in pairs), mostly through excessive fertilizing. and I managed to bring it back. Excessive fertilizing is the easiest way of killing this plant.

It will flower regularly if it is in good health and not stressed (lack of water, light, excessive fertilizer, etc.) The flowers would wind up sticking to the window. The easiest way of telling that it needs more light or water is if the leaves dont open during the day or under good plant lights. I sometimes used it as an water indicator to know when to water the rest of my plants, but I generally wouldnt recommend that to others. Lighting is also critical - Ive lived in several different places since Ive had these plants, and theyve grown differently in every place. Indirect light is best.

I also had to ask a Philippino friend to refrain from eating my plant. I think I put it in more colorful terms that that though: My pot of purple plants always piques people's interest. (Try saying THAT three times quick!)

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.

I've been growing this since 1995. I dug it out of a garden in Hong Kong, moved it to China, and then moved it to England. It loves light, water and fertilizer. It flowers almost all year in warmer climates, and indoors in the winter.

My neighbour, from Zimbabwe, calls it "Sourgrass" and says they eat it back home. When she first saw mine she pinched a leaf and munched it.

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