Daylilies are dependable perennials, they are prolific and colorful bloomers, and they are relatively free of pests. Daylilies are tolerant of drought and flooding, immune to heat stress, tolerant of most soils and grow well in full sun or light shade. They grow well in all areas of South Carolina. They will reach mature size in about three to four years.
Daylilies are long-lived if given even moderate care.
There are daylilies in bloom from late spring until autumn. Individual flowers last only one day but since each plant produces many buds, the total blooming time of a well-established clump may be 30 to 40 days. The most common disease problem is daylily leaf streak. Thrips, spider mites, aphids, slugs and snails are the main pests of daylilies. For more information see HGIC 2102, Daylily Problems .
