When we bought our house we had lots of plants, evidently it had origianlly been professionally done. The previous owners did nothing to it. Nothing bloomed and half of what was there was 3/4 dead. I've saved Golden Seal, rescued Camassia and Day lillies and Hostas and a bunch of other stuff that I never knew was there until one spring after another it popped up and bloomed. I'm not kidding. I feel like I live in a magic garden. If I don't know for sure its a weed I don't pull it out. I actually have aeserium growing as well as trillium and may apples. This is crazy! The long and the short. There are lily of the valleys all over, but they never bloom. Help. I don't want to rip them out, but if they don't bloom they're not going to take up the space of something that will. Can you give me some advice?
