Family

Liliaceae

Botanical Name

HEMEROCALLIS 'Yellowstone'

Plant Common Name

Daylily, Yellowstone Daylily

General Description

The daylily is a popular perennial revered for its reliability, ease of growth and beauty. In midsummer, the highly fragrant ‘Yellowstone’ offers big lemon yellow flowers with orange throats. They are day-blooming and rise from tall clumps of green strap-like leaves that become fully dormant in winter. This is an older cultivar that was first introduced in 1950 by Kraus.

Daylilies are clump-forming and spread slowly via rhizomes. The flowers have six tepals (showy petal-like sepals) that vary widely in size, shape and color. The blooms are commonly held in branched clusters on long leafless stems that stand above the foliage. Each flower opens only once before dying.

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 ornamental in mixed beds and borders, containers and large mass plantings.
