Honeysuckle Coral Vine
Lonicera
sempervirens
introduction
Although a vigorous twining vine,
the native Trumpet Honeysuckle does not spread out of control
quite as easily as Japanese Honeysuckle. The delicate but
striking, twoinch- long, tapered trumpet-shaped crimson blooms
appear from April through summer and are set against a background
of dark green, smooth leaves. The flowers are particularly
attractive to hummingbirds but are not fragrant. Evergreen
in the lower South, Trumpet Honeysuckle may die back during
a hard freeze. Quickly covering fences, lampposts, or mailboxes,
Trumpet Honeysuckle is an excellent vine to use for naturalizing.
Train it onto an arbor or trellis in the full sun for good,
thick coverage.

Trumpet Honeysuckle tolerates most soils except dry sands. As with many vines, some training may be needed to direct growth. Vines will accumulate foliage on top of a fence or other structure but yearly heading back can encourage growth close to the ground. It is best suited for sunny locations and flowers poorly in the shade. Propagation is by softwood cuttings which root easily or layering stem sections where they touch the ground. Several cultivars are available: ‘Sulphurea’ has bright yellow flowers; ‘Superba’ has bright scarlet flowers and broadly oval leaves; and ‘Magnifica’ has large, bright red blooms and is late-flowering. No pests are of major concern. Aphids suck plant juices and coat the leaves with sticky honeydew. The insects can be dislodged with high pressure water sprays from the garden hose. Leaf rollers roll leaves together, then web them in place. Hand pick infested leaves. Four-lined plant bug causes sunken, round, brown spots on the leaves. The injury is sometimes mistaken for a disease. Adult insects are yellowish green with black stripes. Scale insects infest the stems and branches. Close inspection may reveal these insects crusted on the bark. Spray with horticultural oil in the spring.
Pests and Diseases
No diseases are of major concern. Many fungi cause leaf spots,
but chemical control is rarely warranted. Various genera
of powdery mildews form white powder on the leaves. Bacterial
crown gall causes round, warty-looking growths on the stems
near the soil line. Dig out and destroy infected plants.
