Digitalis trojana, a striking biennial foxglove from Turkey, grows to about three feet. With bronze/yellow flowers, each with a white lip and a gold and rust-colored throat and silver/green leaves, it deserves closer inspection and a place in the garden. I read somewhere that it's hardly noticeable until it's in bloom, and its true. One day I had no notion of it, and then the next, there it was in full bloom. Be sure to let it reseed to keep it going on an perennial basis. It's the same with Digitalis purpurea, another beautiful biennial foxglove. It's best to start with a foxglove in its first year and one in its second at the same time, and you will be set for blooms every year after that for a long time - whether you like it or not. Sun/part shade. Zones 4-8. Quarts.
