Daylily, Wynnson Daylily

The daylily is a popular herbaceous perennial revered for its reliability, ease of growth and floral beauty. The hybrid diploid ‘Wynnson’ produces flowers atop a naked branching stem called a scape. The flowering season is early, anytime from mid-spring to early summer depending on climate. The six light yellow, petal-like tepals are oval and wavy edged. The throat blushes light green. These grapefruit-size flowers open in the morning and remain open for at least 16 hours before shriveling up at 24-hours old. They rise from clumps of strappy green leaves that die back in the late fall.
'Wynnson' was bred by Olin Criswell and introduced in 1977. The American Hemerocallis Society gave this cultivar honorable mention accolades during the prestigious Stout Silver Medal competition in 1981. By 1984, the AHS again lauded this cultivar with an Award of Merit.
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.
