    Nursery contributed plant descriptions

    This frilled, award-winning, mid-century classic is a soft pastel yellow that has great carrying power in the garden. It's also a fine flower for bouquets, where its delicately fringed tips make for an almost sparkling effect. It's strong growing and floriferous, with 4-5" laciniated flowers on 4-5' plants.
