Yes, they can. I don't grow them that way, because they grow out in the flowerbed for me. But I had a friend many years ago who lived in Vancouver who had one as a houseplant that was simply stunning

thanks very much,bihai
any advice on it's needs,lighting,water and the like?

I remember that they had a big picture window in the front of the house and she had it sitting on an occasional table in front of this window. So it got a fair amount of light.

Oxalis are basically weeds here, as they are many places in the south. They pop out all over the place with absolutely no prompting. I have to pull them out of every potted plant I have outdoors at some point. The big purple ones, of course, are considered ornamental and you have to buy them, but they are still the same weed. They tolerate full sun outside here, can take either daily rain/water or many days of no water. I would think that they are very forgiving.

again bihai,thank you very much

Inside, give it the best sunlight you have. If not, the plant will become less vibrantly colored and leggy. Grown in plenty of light, it can be stunning in the home.

They do take a break. Just aheads up so you do not throw them away because you think they are dead.

I put mine outside all summer. I bring it in and about Nov it starts to look like it is dying but it is just getting rid of all its leaves and go to sleep.

I stop watering and when I see leaves coming up again which is about 2-3 months, I start watering again.

thanks all, i think i will put it outside because i don't have enough light inside i don't think,and the windows that may have enough light are already being used by other plants. so i guess i should put them where they will get full sun outside?

I have had these indoors and out. Outdoors on my balcony they get HUGE. Indoors, in bright light, they really thrive--they're quite pretty, very cheery! Good luck!!
