Lonicera x heckrottii
The twining, woody, deciduous to semi-deciduous, climber grows vigorously to twelve to fifteen feet tall and spreads to ten feet. It has shiny, oval, bluish-green foliage with reddish stems that provide ornamental interest. The vine develops showy clusters of tubular, fragrant blossoms in coral, pink, and magenta on the outside of the flower and an orange-yellow on the inside of the bloom. It flowers throughout the warm season producing magnificent color and attracts hummingbirds and butterflies. In the fall, it produces inedible red berries. This honeysuckle likes full sun and regular irrigation. Irrigate it more often during the first season after planting to establish a deep root system. Do not over-water this plant and give it rich, well-draining, acidic to neutral soil. It is hardy into the low twenties Fahrenheit and is dormant during the winter. Prune it heavily in late winter to train its growth habit and control its size during the growing season. Watch for aphids in the spring as well as powdery mildew in hot, humid locations, and treat it as needed. Use it as a showy, color plant on arbors, trellises, and fences, or as an espalier near porches and patios for its amazing twining and trailing growth habit. This plant can also be grown in containers. The gold flame honeysuckle is believed to be a cross between two Lonicera species, Lonicera x americana and Lonicera sempervirens.
