General Culture:
Easily grown in average, medium, well-drained soil in full sun. Tolerates shade, but the profuseness of flowering is inversely proportional to the amount of shade. Adapts to a wide range of soils. Prefers moist, loamy soils. Blooms primarily on previous year's stems, so prune to shape after flowering.
Noteworthy Characteristics:
Trumpet honeysuckle is a vigorous, deciduous, twining vine which typically grows 10-15' (less frequently to 20') and is one of the showiest of the vining honeysuckles. Large, non-fragrant, narrow, trumpet-shaped flowers are scarlet to orangish red on the outside and yellowish inside. Flowers appear in late spring at stem ends in whorled clusters. Flowers give way to small red berries which mature in fall and are attractive to birds. Oval, bluish-green leaves are glaucous beneath. This vine is evergreen in the warm winter climates of the deep South, hence the species name of sempervirens (meaning "evergreen" in Latin). Although probably not indigenous to Missouri, trumpet honeysuckle has escaped cultivation and naturalized in some areas of central and southern Missouri.
Problems:
No serious insect or disease problems.
Uses:
Best grown on trellises, fences, arbors or pergolas.
