General Description

With flowers that remain open for at least 16 hours, the Empress Seal daylily also manages to produce an encore of bicolor flowers from late spring to early summer. The daylily is a popular perennial revered for its reliability, ease of growth and floral beauty. The hybrid tetrapolid ‘Empress Seal’ has grapefruit-size flowers that are yellow-centered and coral-lavender. The petal-like tepals have tiny-wave edges and hints of white around the yellow in the throat. These flowers open during the day and rise from clumps of strappy green leaves that die once fall frosts return. Each blossom in the bud cluster lasts no more than 24 hours before shriveling up. This variety was bred by Steve Moldovan & W. Barrere and introduced in 1975. Plants also rebloom several weeks later.

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.

Enjoy this tried-and-true herbaceous ornamental in mixed beds and borders, containers and large mass plantings.
