Species Lonicera (Lo-ni-ce-ra)

Most species of Lonicera are hardy twining climbers, with a large minority of shrubby habit; a handful of species...are tender and can only be grown outside in subtropical zones. The leaves are opposite, simple oval, 1–10 cm long; most are deciduous but some are evergreen. Many of the species have sweetly-scented...flowers that produce a sweet, edible nectar, and most flowers are borne in clusters of two (leading to the common name of "twinberry" for certain North American species). Both shrubby and vining sorts have strongly fibrous stems which have been used for binding and textiles. The fruit is a red, blue or black spherical or elongated berrycontaining several seeds; in most species the berries are mildly poisonous, but in a few they are edible and grown for home use and commerce. Most honeysuckle berries are attractive to wildlife. Many species of Lonicera are eaten by the larvae of some moths and butterflies.  http://www.ars-grin.gov/cgi-bin/npgs/html/splist.pl?6947
