Hmm...there seems to be a lot of confusion about this genus. The Florida Atlas of Vascular Plants says that Sisyrinchium rosulatum is non-native.
http://florida.plantatlas.usf.... Other sites say it's native, some say it was introduced from South America. The Plant Atlas also considers Sisyrinchium atlanticum a synonym for Sisyrinchium angustifolium. I have that species in my front yard but wondered why the ones in the back had pink flowers which I had never seen before. Thanks for your help!
