Beautiful spires of blue/purple flowers characterize this cousin of cardinal flower. Found along streams in the wild, it will grow happily in your garden if the soil has enough moisture, which is a necessity. If conditions are right, it could form a splendid clump. A perfect plant for damp clay, blue lobelia tolerates full sun in cool, northern climates (is that the Keweenaw?) but otherwise prefers some shade.
