Question: I was told that you may be able to help me identify a flower that is taking over my yard. My searches have turned up that it is probably a wild flower that somehow got into our yard in seed form when we purchased dirt 2 years ago to fill in sections of our yard that was low. This flower only produces more flowers with any thing we have tried to use to remove it and I am afraid next year (without more help) my St. Augustine we have worked so hard to grow after purchasing our home (it was a mess when we got it) will be no grass look but only millions of blue wild flowers for 3 months. I am sure without stopping them they will next be taking over all my flower beds also.

Answer: One person's wildflower is yet another's nightmare. What you have is Prairie Nymph (Herbertia lahue/Alophia drummondii), a prized wildflower kind to iris. The are a bit rare but locally abundant where they occur, like all over my parent's hill. I'm proud when they get in the lawn as they were in my granny's as a kid and have never tried to kill them. Not sure at all. Can try Trimec (2,4-D/dicamba/mecoprop) but may be difficult as a bulb. -Greg Grant, Horticulturist, Author, Lecturer
