原生地・分布（英語）:

説明（英語）: Genus of about 200 species of annuals, biennials, and perennials found in dry grassland and mountainous areas, with a very wide distribution, but occurring especially in North America. They range from low-growing alpine species to taller, bushy, clump-forming plants. All have simple, rarely lobed or dissected, usually oblong to lance-shaped or spoon-shaped, mainly basal leaves; the leaves on the stems are usually shorter and narrower. Leaf descriptions below are of basal leaves unless otherwise stated. Fleabanes are grown for their daisy-like, single to semi-double, mainly yellow-centred, white, pink, blue, or purple, sometimes yellow or orange flowerheads, which are borne singly or in corymbs over long periods, mainly in summer. Herbaceous hybrids have leaves 6-15cm (2 1/2-6in) long, and flowerheads that are mostly 4-6cm (1 1/2-2 1/2in) across. Grow in a mixed or herbaceous border, especially in a coastal or rock garden. The flowerheads last well as cut flowers if they are picked when fully open.

耐寒性（英語）: Fully hardy.

栽培（英語）:

繁殖（英語）: Sow seed in containers in a cold frame in mid- or late spring. Divide, or root basal cuttings, in spring.

病害虫（英語）: Powdery mildew affects some hybrids in dry conditions. E. aurantiacus is susceptible to slugs.
