The native honeysuckle vine was discovered in Virginia by a member of the Virginia Native Plant Society. It was named for a local, historical botanist, John Clayton. This honeysuckle has lovely, soft-yellow, tubular flowers that are fragrant and attract hummingbirds. Nectar-seeking moths and other insects also feed at the flowers. Orange-red berries appear after the flowers, which many birds relish. This vine grows 10 to 20-feet tall and has beautiful blue-green foliage. It needs at least a half-day of sun for good bloom. Very winter hardy to Zone 4.
