With unusual-form flowers, 'Frozen Mert' is a nearly all-white daylily selection. The daylily is a popular perennial revered for its reliability, ease of growth and floral beauty. In early to midsummer, the hybrid diploid ‘Frozen Mert’ produces flowers atop a very tall stem called a scape. The six reflexing, petal-like tepals are mostly ivory-white but with lower blushes of pale yellow. Three are narrow and curl like French curls, while the other three are slightly larger with wavy edges. These flowers open in the morning and close by dusk. They rise from clumps of strappy green leaves that die back once fall frosts return. Each blossom in the bud cluster lasts no more than 24 hours before shriveling up. 'Frozen Mert' was bred by Warrell and introduced in 2004.
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.
