    Nursery contributed plant descriptions

    This velvety classic is still the truest deep purple of all dahlias, a color that photos can't quite capture but that modern breeders envy. It was "named for the famous Electrical Wizard with his approval," according to the L.L. Old's catalog of 1939. Grow it and we think you'll agree - it's electrifying!
