|I'm trying to determine what type of flowers I currently have growing in my flower beds. They are purple flowers on green stalks. The structure of the green stalks is similar to that of a daffodil, kind of grass-like. They are obviously a perennial, because I didn't plant them & I've lived there almost two years. The flowers themselves have three petals each. I'm thinking that they may be a bulb, because the stalks are fairly thick at the base. I know they aren't Irises, because I have them in my garden and they don't look at all similar. One last thing...they may close up at night. I went to show them to a friend last evening around sunset, and there were no blooms. However, there were some earlier that day. There were also no dead flowers, so I think they may have closed. I've searched your catalog & others, but I can't seem to find anything that looks similar. Hope you can help!
