General Description

Faintly fragrant, reddish-rose flowers appear on the Sue Rothbauer daylily. This cultivar blooms in mid-spring to very early summer, depending on climate, and reblooms several weeks later. The daylily is a popular perennial revered for its reliability, ease of growth and floral beauty. The hybrid diploid 'Sue Rothbauer' was bred by K. Carpenter and introduced in 1983.

This daylily produces wide-opening flowers atop a branching naked stem called a scape. The scapes rise from clumps of strappy green leaves that are partially evergreen over the winter, particularly in mild climates. Each petal-like tepal in the flower is deep red-rose or rose-coral and the flower throat is pale yellow-green. Each 6.5-inch-wide (17 cm) blossom in the bud cluster opens in the morning but shrivels up before it's 16-hours old.

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.
