My oxalis plants look their best this time of year. The petite pink oxalis came from my grandmother’s plant which has been shared with many generations of our family. In the other pot, I have a white flowering and a red leaf oxalis. These will die back but they always return. I have had these plants for longer than I can remember. I always bring them inside for the winter months. These plants can often be found in March at grocery stores for St Patrick’s Day. The leaves look like shamrocks.
