- Description
-
Blue Bead is a small, flowering, herbaceous perennial in the lily family usually found in large spreading colonies in moist, cool woods, spruce-fir forests, or open, mountain slopes. The plant is composed of 2 to 4 curved leaves, small flowers at the ends of long, 20 inch, stalks, and dark blue, bead like berries that give the plant its common name. The plants slowly spread by underground rhizomes or can be propagated by division or by seed. The genus is named in honor of the former governor of New York, DeWitt Clinton (1769-1828) The species name, borealis, meaning "of the north", alludes to the plant's preferred environment in Canada and the Northeastern United States.
Blue Bead does best in shaded sites with organically rich, moist, acidic soils preferred. It does not do well in heat and will decline when temperatures rise above 75 degrees F. However, in the right environment and the right amount of patience, the plant will make an excellent ground cover.
Bees will suck nectar or collect pollen from Blue Bead flowers; flies and beetles as well feed on pollen and nectar. Short-tongued bees and flies are usually non-pollinating.
Insects, Diseases, and Other Plant Problems:
Slugs and snails.
