Toad Lily (Tricyrtis)
Zone: 4 to 9
Shade
Height: 1′ to 3′
To me Toad Lilies* look like they belong on an exotic island somewhere with their brilliant purple and blue flowers that appear in the fall.
They can be a little tricky to get started (it took me 3 tries to get one to come back the next year), but they are so pretty that I think they’re worth the effort. Keep them happy with regular water and fertilizer.
Fortunately, they are actually quite hardy, and are one of the few autumn blooming perennials that does well in the shade.
