説明（英語）: Genus of about 250 species of annuals, biennials, perennials, and subshrubs from a variety of habitats, including well-drained, mountainous sites to moist woodland, in the N. hemisphere, particularly North America. The few shrubby species are mainly from South Africa. Most asters have alternate, entire, simple, lance-shaped leaves, some hairless, some softly hairy. The daisy-like flowerheads are either solitary or borne in terminal corymbs, racemes, or panicles on erect to spreading, usually branched stems; they have strap-shaped, female ray-florets in white, pink, blue, or purple, and tubular, hermaphrodite, usually yellow disc-florets. There are asters for almost all garden situations, including borders and rock gardens, streamsides, dry sites, and wildflower gardens. In frost-prone areas, grow the tender, shrubby species in a cool greenhouse.

耐寒性（英語）: Fully hardy to frost tender.
