Both of the hives are doing well! We see bees in the flowers and flowering herbs in our yard every day. The bees enjoy lavender and borage, of course, and we also see them in the oregano. If you aren't already planting borage, I would encourage you to plant some if you want to attract pollinators;
here's some good info about borage. It has pretty, star-like flowers, and it's also believed to have medicinal benefits.
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!
