General Description

Flowers upward of 8 to 9 inches (20 to 23 cm) in diameter are seen on the Knower Spider daylily in early summer. The daylily is a popular perennial revered for its reliability, ease of growth and floral beauty. The hybrid diploid ‘Knower Spider’ produces unusual-form flowers atop a naked, very tall stem called a scape. The six petal-like tepals are creamy bright yellow. Three tepals are narrow and curl or cascade like ribbons. The other three tepals are more tongue-shaped and have a faint fuchsia-pink arc across them. These flowers open in the morning. They arise from clumps of strappy green leaves that die back each winter. Each blossom in the bud cluster closes and shrivels up by the time they're 24-hours old. 'Knower Spider' was developed by breeders Knower & Warrell and introduced in 2003.

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.
