The bumblebees are always attracted to my sunflowers, but this year, they've discovered the wonders of my shrimp plant and are constantly stuffing their fat little heads deep into the delicate flowers, leaving little nectar for the hummingbirds, I expect. They also like the Red Hot Sally salvia, which the hummingbirds have never sampled. Interestingly, I've never seen a bumblebee or any other bee on my feeders. Plenty of wasps, but never any bees. Oh well. At least I like bumblebees. :)
