Thank you everyone for the supportive words! We all share a love of these beautiful visitors to our gardens, and of the things we plant, maybe more for them than for ourselves. These days, when choosing a plant, I want to know if it's resistant to deer and rabbits, and whether it attracts hummingbirds and butterflies. If the answers are all "yes," I'll consider it. As for the hummingbird moth, it was more luck in timing than anything else. What a strange and beautiful creature!
And thank you for the kind words about my petunias too! They are a total mistake. I ordered something called Tidal Wave from White Flower Farm--they're supposed to be a silver-white color, and I got these instead. I had already planted them by the time I realized that those purple-ish flowers were never going to be white so White Flower Farm has promised to send the proper order next spring. Meanwhile, I'm obviously not the only one enjoying their mistake!
