Green Ball produces perfectly round, fuzzy, ball-shaped, lime green flowers, up to 3 in. across (7 cm), in late spring and summer. The vivid blossoms rise on stiff, erect stems clad with long, glossy, dark green leaves. This hardy annual or short-lived perennial is a charming addition to beds and containers. It is prized by florists, thanks to its long vase life (up to two weeks), and can even be dried to last longer.
