Turtlehead adapts beautifully to garden conditions. Plants form an upright, bushy mound of green foliage, bearing upright stems of large hooded flowers shaped like the head of a turtle, in late summer. Best in a moist or wet site, this also adapts well to drier border conditions. Terrific at the waterside. Excellent for cutting. Showy and long lived. It is the host plant for the Baltimore Checkerspot Butterfly.
