The other plant our bees love is Crocosmia, or "Lucifer" flowers. Here's a photo from Wikipedia--and it's perfect because we have had hummingbirds visiting ours quite a lot, too (or maybe just one hummingbird who returns quite a lot).
We have been seeing butterflies in the yard a lot, too. It's been nice to see so much activity. Trish's close attention to gardening shows a lot of rewards!
