I had no idea the hummingbirds loved coleus blooms so much! This year I went on vacation and the coleus bloomed. I normally pinch the blooms off; however, I have seen hummingbirds at them every day since I've been back. I think I'll leave them. They don't look so bad.
The birds and bees love my echinacea and bee balm, among others. We're getting a second, smaller bloom from the bee balm which bloomed in late June. Flowers with tubules are especially attractive to hummingbirds, but I don't think I've ever seen one.
