Lonicera reticulata aka Grape Honeysuckle

Lonicera reticulata, or grape honeysuckle, belongs to the honeysuckle family, Caprifoliaceae. This woody perennial grows as a sprawling shrub or weak climber. Its native range needs care in interpretation. Kew lists southeastern China, while NC State includes the midwestern United States and eastern China. NC State notes that these populations may represent two similar species. The name reticulata refers to the net-like veins in its leaves.

Plants reach 3–15 feet [0.9–4.6 metres] tall. They spread 3–5 feet [0.9–1.5 metres] wide. Several stems form an arching mound or scramble upward. Growth proceeds at a moderate pace. The leaves fall each year. They grow in opposite pairs and have a simple, oval shape. Their surface feels leathery and lacks hairs. Leaves measure 0.25–0.5 feet [0.08–0.15 metres] long. Their width is about 0.08–0.25 feet [0.03–0.08 metres]. Foliage may be green or gray-silver.

Small, yellow flowers crowd the branch tips in cymes. Each funnel-shaped bloom has lobes that curl back. The stamens extend beyond the flower. Chicago Botanic Garden also lists white blooms. Its flowering record spans May through October; NC State lists summer. Bees, butterflies, and hummingbirds visit the flowers. Red to burgundy berries provide a fall display. The fruit clusters sit above opposite leaves joined together. Both flowers and berries measure less than 0.08 feet [0.025 metres] across. The supplied sources do not establish whether people can safely eat the fruit.

Grow this plant in sun or partial shade. Moist soil and full sun produce more flowers. It accepts clay, loam, sand, and soils rich in organic matter. Good drainage matters, though soil may range from moist to dry. NC State lists neutral soil conditions. Chicago lists USDA zones 4–9, while NC State lists zones 4–8. Flowers form on old wood. Prune after flowering when pruning is needed. Seeds and stem cuttings offer ways to raise new plants.

Grape honeysuckle suits informal borders, cottage gardens, and containers. Its form also serves as an accent or screen. Flowers and fruit add interest at different times. NC State rates its upkeep as low. It reports few pest or disease concerns, though powdery mildew can occur. Deer tend to leave the plant alone.
