HEMEROCALLIS

Tuberous, somewhat fleshy roots give rise to large clumps of arching, sword-shaped leaves— evergreen, semievergreen, or deciduous, depending on daylily type. Deciduous types go completely dormant in winter and are the hardiest, surviving without protection to about –35°F/–37°C; where winters are very mild, however, they may not get enough chill to perform well.

Evergreen kinds succeed in mild-winter regions as well as in colder areas, but they need a protective mulch (such as a 4–6-in. layer of hay) where temperatures dip below –20°F/–29°C. Semievergreen sorts may or may not retain their leaves, depending on where they are grown.

Clusters of flowers like lilies appear at the ends of generally leafless stems that stand well above foliage. Older yellow, orange, and rust red daylilies have in most part been replaced by newer kinds in an expanded range of colors and patterns; both tall and dwarf varieties are available. Many species daylilies exist, but only a few are offered by nurseries; most of those available are hybrids.

Few plants are tougher,more persistent, or more trouble free. Daylilies adapt to almost any kind of soil. You can set out bare-root plants at any time during the growing season; spring and summer are better in cold-winter zones, while fall and winter are preferred where winters are warm. Plant from containers at any time from early spring through mid-autumn (year-round in mild-winter areas). For best results, provide well-drained soil amended with organic matter; give regular moisture from spring through fall. When clumps become crowded (usually after 3 to 6 years), divide them in fall or early spring in hotsummer areas, during summer in cool-summer regions or where growing season is short.
