The glowing, orange-yellow flowers are extremely attractive, constantly blooming for weeks. Leaves are deeply dissected, almost thread-like in appearance. Rich, fertile soils tend to produce unusually tall, lanky plants. Requires full sun. Sow in early spring, seedlings are not winter hardy. Highly recommended.
