While not truly black, the flowers of 'Black Pearl' do flirt with blackish maroon hues. The daylily is a popular perennial revered for its reliability, ease of growth and floral beauty. The hybrid diploid ‘Black Pearl’ produces rather small flowers atop a tall stem called a scape in very early summer. The six petal-like tepals are tongue-shaped and a powdery maroon with smears of very dark red (black). The inner throat is yellow and green. These fragrant flowers open during the day and rise from tall 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. The short-growing 'Black Pearl' was bred by F.H. Knower and introduced in 1963.
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.
