do oxalis overtake other oxalis?

Question

I’ve had several varieties of oxalis plants. I’ve always had excellent luck with these plants. But, I noticed that two varieties have disappeared completely while other varieties have flourished. I wondered if I shouldn’t plant certain varieties together.

Answer 1

Yes, they will compete. The more vigorous will survive and take over the entire bed. They tend to be very aggressive in nature, and will do this to other plants that are not related as well.

It is recommended to keep them in separate containers to avoid them getting out and naturalizing.
