Lemon-yellow, summer-long cup flowers open from red buds on a stalwart, shrubby perennial. It's native to sunny meadows of the east coast. Wonderful in a naturalistic garden or for dependably brightening a border. And, if you have them in your neck of the woods, they attract sphinx moths!
Minimum temperature: -30° F
