Glaucous Honeysuckle

Lonicera dioica (loh-NIS-er-ah dy-OH-ih-cah)

Family: Caprifoliaceae Native Vine (vertical)

Limber honeysuckle is a woody, loosely twining, perennial shrub that sprawls or climbs on nearby vegetation. It is native to subarctic North America through the central and eastern United States. It is found in boggy areas and other wet sites at high elevations in coniferous and deciduous woods and thickets, often in sandy or rocky ground. The plant is rare in North Carolina and found only at high elevations in the Mountains. It is a member of the honeysuckle family (Caprifoliaceae). The species epithet is Latin for “dioecious” (male and female flowers on separate plants) and is based on a misinterpretation of the dried specimens examined by early European botanists. Flowers have both male and female parts. Limber honeysuckle will grow in full sun to partial shade in a variety of moist to dry soils with good drainage. It flowers more profusely in full sun, on moist soil. Limber honeysuckle is low climbing with branches arching or twining 3 to 10 feet from the plant. It can be pruned, but keep in mind that flowers will appear on old growth. This honeysuckle succeeds very well under cultivation. If given the support of a stout central stake, it will form a low, spreading, rather elegant bush. Diseases, Insect Pests, and Other Plant Problems: No known insect or disease problems. Powdery mildew may occur. Deer tend to avoid this plant. More information on Lonicera .
