Plant ID help please
I purchased this perennial plant several years ago and now that I'm labeling my yard, I can't remember what it is! It blooms in late spring through mid-summer. Its flowers close in the evening. If you squeeze the closed buds, you get a juicy like liquid. In fact, I believe that the name had "grape" in it...
Could it be a grape hyacinth?
Edit: Identified! It's a Spiderwort plant.
