Identification: Another Unknown

This Plant was also inherited. The leaves open in the morning, and close in the evening. This plant sometimes has tiny white flowers. I am just curious as to what it is.

 

Looks like some kind of Oxalis, maybe O. regnelli.

 

yup, one of the many oxalis.

 

I have green and purple ones togther growing in the same pot. Easy plants. They go semi dormant in the winter.
