Master Gardener: What to do if you want pink oxalis in your yard – Daily News
Master Gardener: What to do if you want pink oxalis in your yard. Pink wood sorrel, or pink wild oxalis, is a perennial in mild climates and an annual in areas prone to freezing temperatures. However, it can be invasive so be careful where you plant it. I have a favorite volunteering plant in several places in my yard in Orange County, and I see it also at my Dad’s house. It is a type of oxalis – growing in a clump with many rather small pink flowers.
