General Description

A sight to see when in bloom, the Big Ross daylily is delightful - flowers akin to a two-colored, six-armed starfish the size of a dinner plate. The daylily is a popular perennial revered for its reliability, ease of growth and floral beauty. The hybrid diploid ‘Big Ross’ produces huge flowers atop a very tall stem called a scape. The six petal-like tepals curl and cascade. They are mainly yellow, but there is a notable blush of rusty rose at their ends. These fragrant flowers open during the day and rise from tall clumps of strappy green leaves that remain semi-evergreen across the winter. Each blossom in the bud cluster lasts no more than 24 hours before shriveling up. In good growing conditions, this selection will rebloom several weeks later if not nipped by the first fall frosts.

'Big Ross' was bred by Dan Bachman and introduced in 2001. The American Hemerocallis Society gave it an award of merit, and in 2005 it received an honorable mention nod in the quest to receive the AHS's prestigious Stout Silver Medal.

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.
