説明（英語）: Genus of approximately 100 species of bulbous perennials, mainly from wooded habitats and scrub in Europe, Asia south to the Philippines, and North America; there are also innumerable garden hybrids. The bulbs are composed of overlapping, fleshy scales and are sometimes rhizomatous. The stems are unbranched and usually erect; in some lilies, roots develop on the stems just above the bulb. Numerous elliptic to lance-shaped or linear, glossy, mid- to dark green leaves are arranged in whorls or spirals, or are scattered alternately up the stems. Lilies are often tall-growing, attaining a height of up to 3m (10ft), but do not spread (therefore only height measurements are given in the entries below). The showy, sometimes very fragrant flowers are solitary or borne in racemes, panicles, or umbels, and are followed by 3-parted capsules containing flat, papery seeds. The flowers may be upward-facing, horizontal or outward-facing, nodding, or pendent. They may be cup- to bowl- or bell-shaped, trumpet-shaped, funnel-shaped, turkscap (in which the blooms have strongly reflexed tepals), or occasionally star-shaped; each with 6 stamens and 6 tepals (see panel above). The tepals, occurring in most colours except blue, may be plain or marked with lines, spots, or papillae. Three categories of flower size - small, medium, and large - are used in the descriptions below. For turkscap, bowl-, cup-, and star-shaped flowers: small is up to 5cm (2in) across; medium is 5-7cm (2-3in) across; large is over 7cm (3in) across. For trumpet- and funnel-shaped flowers: small is up to 7cm (3in) long; medium is 7-10cm (3-4in) long; large is over 10cm (4in) long. Lilies may be grown in many sites, including woodland and wild gardens and among shrubs or herbaceous plants. They are often grown for exhibition and provide excellent cut flowers. A few are suitable for a rock garden. Many also grow well in a large container on a patio. In frost-prone climates, grow half-hardy lilies in a cool greenhouse. Lilies are classified into 9 divisions:

耐寒性（英語）: Fully hardy to half hardy, but young growth may be damaged by frost.

栽培（英語）:

繁殖（英語）: Sow seed as soon as ripe; sow seed of hardy lilies in containers in a cold frame, and of half-hardy lilies at 13-18°C (55-64°F). Remove scales, offsets, or bulblets from dormant bulbs as soon as the foliage dies down, or detach stem bulbils (where these are produced) in late summer.

病害虫（英語）: Lily beetle, aphids, slugs, thrips, leatherjackets, and wireworms, as well as small mammals such as rabbits and voles, may be a problem. Various fungi can infect lilies either below or above ground. Grey mould (Botrytis) is sometimes a problem, especially in a wet, cool spring. Viruses may be troublesome, although some cultivars are virus-tolerant and grow well despite infection.
