Identification: Plant ID Please: Clover/Shamrock ID w/ White flowers

I got a clover/shamrock type plant from a friend, I was wondering if someone could help me specifically ID it. It has 3 triangle shaped leaves that anchor at a center point on a long stem. It has a tuber style root (seen when I repotted it) and it has small white flowers that it shoots up when it blooms.

It appears similar to another post which was identified as Oxalis corniculata.

Every Oxalis I've looked at has either had the wrong color flower or the flower wasn't the same shape. I've attached pics of the plant and a close up of the flowers. Thanks in advance.

 

Certainly an Oxalis, tho' I don't know which

 

yuppers that is an oxalis alright!

 

This looks like Oxalis regnellii, commonly called wood sorrel or false shamrock. Those lucky enough to live in zone 7 or warmer can enjoy this perennial in the garden.

 

yes but! becarefull it can take over!

 

Thanks for the ID and I now keep it well away from my other plants and since I live in a 4th floor condo there won't be any thought of adding it to a garden of any type.

Much appreciated!

 

I also have an O. regenellii, that loved the end of my parents' kitchen table, where it got plenty of light from the picture window. My dad enjoyed it so much that he was just about as sad to see it go as his own daughter, when I got married and moved out. I read online that you can split them, so I did and gave him half. Both plants looked like they'd been mugged for about two weeks, but quickly bounced back with new growth and a burst of flowers. So even though you, like I, can't plant it outdoors, it would be easy enough to have two plants to enjoy!

 

Oxalis regnellii is an obsolete name for the plant.

The correct name is Oxalis triangularis.
