The daylily is a popular perennial revered for its reliability, ease of growth and floral beauty. Blooming in late mid-spring to very early summer (depending on climate), the hybrid diploid Summer Interlude daylily displays predominantly dark red flowers on tall stems called scapes. The throat in the flower is contrasting greenish yellow.
'Summer Interlude' was bred by D.F. Hall and introduced in the mid-1950s. The scapes rise from clumps of strappy green leaves that are die back in winter. Each blossom - comprising six petal-like tepals - in the bud cluster opens in the morning but shrivels up before reaching 16-hours old.
Daylilies are clump-forming and spread slowly via rhizomes. The blooms are commonly held in branched clusters on long leafless stems that stand above the foliage. All daylilies are easy to grow if provided full to partial sun and average soil with good drainage. Deciduous daylilies are the hardiest and survive in the coldest reaches of their range; however they may struggle in areas with mild winters. Evergreen types grow well in all but the most tropical regions but require protection where winters are harsh and cold. Their clumps spread over time and may need to be divided every three to four years. After plants bloom, it is wise to shear back their foliage to allow for a fresh flush of growth.
