Rainy Side Notes
Our American native, boltonia, has been used for some time in American gardens, although we have a long-term reputation to live down about our indifference to indigenous plants. "You Americans do not appreciate your wild flowers," English garden author, William Robinson once said during the early 1900s. "We have to bring them over to England and cultivate them for a while before you will notice them."
Well, we noticed. The tall boltonia species is wonderful in the back of the border and definitely not a shy child. Louise B. Wilder called them "the fleecy Boltonias." Its tall, lanky frame covered with numerous white daisy-like flowers in late summer to fall is welcome in the waning garden. It definitely needs staking or it flops over with ease. If you like the floppy look, give it plenty of flop room, as it will sit on top of everything it falls on.
