The daylily (Hemerocallis) is considered a sure bet perennial. They thrive throughout most of the country, with the exception of the very deep south. They tolerate less than ideal conditions and will bloom faithfully for years with virtually no attention. As the name implies, daylily flowers open in the morning and die by nightfall. Each flower stem typically has at least a dozen flower buds, and the plant stays in bloom for many weeks. They should be planted in every garden. Hemerocallis Black Stockings is known for its striking and outstanding characteristics. Its blooms are blackish and dramatic. Like the typical daylily it has 6-petals medium to large in size in a radial pattern. Known to produce an extended blooming and long-lasting bloom display. The foliage is dense and grass-like, while not the main attraction, easy to care for. Considered a low maintenance plant. A very reliable performer, making it a popular choice among daylily enthusiasts.
