This ornamental Caucasian hardy perennial grows in any garden soil, and is easily increased by seeds, division, and from root cuttings under glass. It grows about 2 ft. high, and has oblong serrate leaves, and large bright-orange Marguerite-like flower heads in July and August; valuable for cutting. Other species are grandiflora, Helenium, Hookeri, and Oculus-Christi - all 2-3 ft. high, and with yellow flowers.
