I had meant to get a bright red Monarda didyma to attract ruby-throated hummingbirds, but found this magenta one 'Raspberry Wine' instead. It's done remarkably well since it was planted last summer. Being next to the bird bath has definitely helped provide moisture that's otherwise in short supply this summer.
It's struggled a bit with powdery mildew (like most Monarda spp.), but provides a welcome patch of color nevertheless.
This morning, I saw a hummingbird spending time methodically working through open flowers, extracting nectar (naturally, I didn't have my camera!) Fortunately, the inflorescences have lots of flowers which open over an extended period of time.
