Can you identify what type of houseplant this is"

I have one in purple and one in green. It has 3 leaves similar
to a 4 leaf clover. It closes up at night and opens up in
daylight. It requires a lot of water, if not reveived it
wilts, but perks back up when watered. It puts out little
bell like flowers occasionally.

Thanks..

They are two species of oxalis. The one with red leaves may be Oxalis regnellii, but here are many species in the trade. A few are sold as shamrock in the spring. Derek
