Lonicera sempervirens 'Sulphurea.'
Lonicera sempervirens 'Sulphurea,' commonly called trumpet honeysuckle, is a vigorous, deciduous, twining vine that grows 10-15' (less frequently to 20') and is one of the showiest of the vining honeysuckles. It is primarily native to the southeastern U.S.
Large, non-fragrant, narrow, trumpet-shaped flowers are yellow. Flowers appear in late spring at stem ends in whorled clusters. They are attractive to hummingbirds, butterflies, and bees. Inedible red berries from late summer to early fall can be ornamentally beautiful. The small red berries are attractive to birds. Oval, bluish-green leaves are glaucous beneath. This vine is evergreen in the warm winter climates of the deep South.
It is quickly grown in average, medium moisture, well-drained soils in full sun. It will grow in some shade, but the best flowering is in full sun. Best in humusy, organically rich soils with good drainage. This is a twining vine that needs a support structure to grow unless allowed to sprawl as a ground cover. Prune as needed immediately after flowering.
