Bugbane, by F.T. McKinstry. Bugbane (cimicifuga ramosa) grows in my cosmic garden. It is also called black snakeroot, or black cohosh, depending on where you look it up. But whatever it's called, it is a truly spectacular perennial. It grows eight feet tall, has deep, dark purplish green leaves and in very later summer blooms with creamy white, drooping spires that smell wonderful and attract bees and butterflies like no tomorrow.
