buddleia globosa

I love this plant, and the bees do too, though it's actually a Butterfly Bush. I've been known to say it's rare-- but I'm going to amend that-- just less common than the more usual form of buddleias (which have more cone-like, often lavendar colored flowers, and bloom later in the season). I've never really worked with rooting cuttings, myself, but I've heard that buddleias were easy, and friend Bob had success taking a snippet from this, which is now flowering in his yard for the first time.
Fast-growing, this is about 10 feet tall by 10 feet wide by the end of the season, and we cut it down to about 5 feet in the winter. Butterfly Bushes (the other kind) came up as volunteers in a number of places this year, and many have been escorted to our new planting beds. We're seeing more Pipevine Swallowtail butterflies (black with blue) this year than we've seen in our yard before.
