The Large-Flower Wood-sorrel flower looks pretty, but this plant is a weed introduced from elsewhere.  We have a couple of very small patches of it this year. I think it is new as I have not noticed it before.

I’ve heard that Oxalis spreads if you try to pull it out of the ground and we don’t want to use poisons.  Does anyone have suggestions on how to control it?

This flower is very eye-catching but the pink Large-flower Wood-Sorrel plant is a weed in Victoria.
