'Zowie! Yellow Flame' (Zinnia elegans) is the first semi-tall bicolor zinnia, sporting a uniquely fiery design that flames from a scarlet-rose center to yellow petal edges. It blooms from early summer until frost, is easily grown from seed, reaches 29 inches tall and 27 inches wide, tolerates heat and drought, and is excellent in the garden or in containers. 'Zowie!' is also a superb cut flower, with blooms lasting as long as two weeks in water.
