Helianthus salicifolius A.Dietr.

Helianthus salicifolius 'First Light'(애기해바라기 '퍼스트 라이트') was introduced in 2002 by Blooms of Bressingham. Unlike its parent, which grows eight-feet tall and has a loose and open habit, 'First Light' is a fireplug of a plant reaching only three feet in height. As the common name suggests, the foliage of the willowleaf sunflower is narrow, linear and tightly arranged on a strongly pyramidal plant.

Helianthus debilis is a species of sunflower known by the common names cucumberleaf sunflower, beach sunflower, weak sunflower, and East Coast dune sunflower. It is native to the United States, where it can be found along the Atlantic and Gulf Coasts. It is known elsewhere as an introduced species, such as South Africa, Australia, Taiwan, Slovakia, and Cuba.

This species may be an annual or perennial herb. It is usually perennial but it may last only one season in climates where freezes occur. It can reach 2 meters tall. The stem grows from a taproot and may grow erect or decumbent. It can also spread along the ground, becoming a dense groundcover.The leaves are usually alternately arranged, and are variable in shape and size. The largest are up to 14 centimeters long by 13 wide. The showy inflorescence is a single flower head or an array of two or three heads. There are up to 30 lance-shaped phyllaries each up to 1.7 centimeters long. There are up to 20 or 21 ray florets, each up to 2.3 centimeters long. They are usually yellow in the wild, but cultivars have been bred to bear whitish,reddish, or orange florets. The center of the head is filled with many red, yellowish,or purplish disc florets. The fruit, a cypsela, is roughly 2 or 3 millimeters long.
