About Lilies
Nearly 100 species and thousands of hybrid members of the Lilium genus are sensuous, sumptuous stars of cottage gardens and formal floral arrangements. They are highly varied in appearance and growth habit. All are native to the northern hemisphere’s temperate zone.
You’ll find their showy flowers along mountain trails and country roadsides as well as in carefully maintained gardens. All are summer bloomers; most are true bulbs (they lack tunicate sheaths and have open scales).
The North American Lily Society classifies lilies in nine divisions, but most commonly planted cultivars comprise just four informal categories, listed above.
Lilies first became popular in North American gardens in the 1930s, when growers first produced reliable stocks and began mass cultivation.
Popular Asiatic hybrids bloom in early summer, with their open flowers facing up, down, or outward.
Aurelian hybrids stem from the Asiatic hybrids but bloom in midsummer with fragrant, bowl-shaped or fluted flowers.
Highly fragrant Oriental hybrids produce huge, bowl-shaped blossoms to 10 in. (25 cm) wide from late summer to early autumn.
Species lilies vary in habit, flower form, and bloom season. Colors run the gamut of copper, pinks, reds, whites, and yellows, even bicolored, with stripes, bands, and speckles sometimes adding to their allure.
Lily flowers may be shaped like trumpets, shallow bowls, funnels, or cups. Some species and cultivars have as many as 20 to 30 blossoms on a stem. Many have petals that reflex—curve back gracefully—to reveal large red, brown, or golden anthers loaded with pollen on long green filaments.
Planting and Caring for Lilies
Plant most lilies in the autumn; in zones 9 and 10, place the bulbs in the vegetable keeper of a refrigerator for 4–6 weeks prior to planting unless your bulbs have been prechilled.
The planting soil should be deep, well-drained, and loose. Sandy loam mixed with humus is best; supplement it with organic matter, if needed.
Lilies thrive with their tops in the sun and their roots kept cool by shade cast from shrubs or bushy perennials. Lilies in exposed sites should be heavily mulched during summer to keep their roots cool. Water them regularly to keep their soil moist.
The planting soil should be deep, well-drained, and loose. Sandy loam mixed with humus is best; supplement it with organic matter, if needed. Lilies thrive when their tops are in full sun, while their roots remain cool in shade cast from surrounding shrubs or bushy perennials.
While lilies are generally hardy, it’s best to protect them with a heavy layer of mulch in U.S.D.A. Plant Hardiness Zones 6–7 if they will overwinter in the garden; all lilies benefit from mulching during the summer to keep the bulbs cool and moist while their foliage and flowers are in full or filtered sun.
Plant lilies in borders or containers, or group them as garden accents. They also are excellent cut flowers. Deadhead spent blooms, leaving as much stem as possible––the foliage provides energy to developing offsets and the parent bulb.
Force lilies by chilling their bulbs, then planting in a deep pot filled with soil, covering the bulbs. Water, then place the container in a warm, well-lit location.
