Common honeysuckle (Lonicera periclymenum) is also called European honeysuckle or woodbine. Native to Europe, North Africa and western Asia, it has naturalized in some areas of North America such as Nova Scotia, Ontario, New England and the Pacific Northwest. It is a deciduous shrub with a vine-like habit, growing 10 feet tall and occasionally to 20 feet tall. Leaves are ovate to obovate, about two inches long, appearing on the stems in pairs. Leaves are dark green above and blue-green underneath. Two shades of green appear in the center of the leaf, which has creamy white edges. New leaves emerge in spring and mature as smooth leaves by summer, becoming hot pink in autumn. Buds are pink. Colorful flowers open with ivory interiors and purple exteriors. Two-lipped flowers, each two inches long, bloom steadily in summer and more sporadically in autumn to frost, in three to five whorled terminal spikes that give way to glossy, red berries. Honeysuckle also has strong nocturnally scented flowers attracting large pollinating hawk moths that roam dense bushy and woodland areas.
Light
Common honeysuckle prefers dappled sunlight, but it will grow in full sun to part shade. Give the plant a similar environment to its native habitat of scrub and woods. If possible, shade the roots and let the plant climb towards the sun.
Soil
Give common honeysuckle any fertile, rich, well-drained soil.
Water
Water newly planted honeysuckle consistently. Keep the soil evenly moist until the plant shows signs of vigorous growth. Once established, it is quite drought tolerant. Water only if summer droughts last two weeks or more, offering at least one inch of water per week. Adding about two inches of organic mulch around the plant’s base will prevent water from evaporating.
Temperature and Humidity
Honeysuckles usually thrive best in cooler regions with cooler summer climates. Place in part afternoon shade where summers are especially hot.
Fertilizer
If planted in fertile soil, the honeysuckle will grow vigorously without any added fertilizer. If needed, encourage blooming by applying a low-nitrogen fertilizer in spring such as 2-10-10, 0-10-10 or 15-25-10. Too much nitrogen will encourage more growth in the leaves and not enough in the flowers. Such “flushes of foliage growth” could make the plant more susceptible to pests. Learn to read and understand garden fertilizer labels to give each plant exactly what it needs.
Pruning
Once established, most honeysuckle plants will grow vigorously. Prune your common honeysuckle as you would any shrub or vine, removing dead or damaged twigs and branches throughout the season but save any hard pruning for after bloom. Early-blooming vining varieties that bloom on last year’s growth, like common honeysuckle (Lonicera periclymenum), benefit from being cut back by one-third after the blooming period is over. If the vine gets out of control, cut it two feet above the ground.
Other Varieties
Early Dutch Honeysuckle (Lonicera periclymenum ‘Belgica’ ) plants bear streaked, raspberry red flowers.A popular woodbine (Lonicera periclymenum ‘Serotina’) produces flowers that are dark red on the outside and yellow and white inside.Berries Jubilee (Lonicera periclymenum ‘Monul’) have yellow flowers, giving fruit to bright red berries.
Propagating Common Honeysuckle
Semi-ripe cuttings can be taken for propagation in summer. Put the cuttings in a well-draining soil and wait for them to take root.
Common Pests and Diseases
While there are rarely any serious insect or disease issues, watch for honeysuckle aphids and scale. Leaf roller, dieback, and blights may also arise. Growing honeysuckle in regions with hot and humid summers could result in powdery mildew and leaf spots, which is why it’s best to grow honeysuckle in cooler regions where it will thrive.
