Late Dutch Honeysuckle (Lonicera periclymenum ‘Serotina’) is an ornamental vine valued for its aesthetic appeal and fragrant blossoms. It is a versatile addition to landscapes, capable of covering structures or providing a natural backdrop. Its attractive flowers and subsequent berries contribute to its popularity.
Understanding Late Dutch Honeysuckle
Late Dutch Honeysuckle is a deciduous twining vine, vigorously climbing 10 to 20 feet. Its oval-shaped leaves provide a dense green backdrop, remaining vibrant throughout the growing season before dropping in autumn.
The plant produces distinctive, highly fragrant tubular flowers from late spring through summer, often extending into early autumn. These bi-colored blooms are typically rich red or purplish on the outside and creamy yellow or white on the inside. Following the flowering period, small, bright red berries develop in autumn, adding visual interest and providing a valuable food source for birds.
Planting and Site Selection
For successful establishment and robust growth, plant Late Dutch Honeysuckle in full sun to partial shade. It flourishes with at least six hours of direct sunlight daily, which encourages abundant flowering. While it tolerates some afternoon shade, especially in hotter climates, more sun generally leads to more prolific blooms.
The vine prefers well-drained, fertile soil rich in organic matter. Amend heavy clay soils with compost before planting to improve drainage and aeration. The best time to plant is typically spring or early autumn, allowing root establishment before extreme temperatures. Dig a hole twice as wide as the root ball and of similar depth, ensuring the top of the root ball is level with the surrounding soil. Backfill with soil, gently firming it around the roots, and water thoroughly to settle the soil and eliminate air pockets.
Ongoing Care and Pruning
Consistent watering is important for Late Dutch Honeysuckle, especially during its first year. Established plants tolerate short dry periods, but supplemental watering during prolonged droughts helps maintain vigor and flower production. Applying organic mulch around the base helps retain soil moisture and regulate temperature.
Fertilization is not always necessary if the soil is fertile. If growth appears sluggish or flowering is sparse, apply a balanced granular fertilizer in early spring before new growth begins. Pruning is a regular and important aspect of care, managing size, encouraging bushier growth, and promoting continuous flowering.
Pruning Techniques
Light pruning can be done after the main flush of flowers to remove spent blooms, a process known as deadheading, which encourages new development. More substantial pruning, including removing dead, damaged, or tangled stems, should be performed in late winter or early spring before new growth emerges. This timing allows shaping the vine without sacrificing current season’s flowers. For older, overgrown plants, a hard rejuvenation prune can be performed by cutting the entire vine back to 1-2 feet from the ground. This encourages strong new growth and revitalizes the plant, though it may result in reduced bloom the subsequent season.
Benefits and Management
Late Dutch Honeysuckle offers several garden benefits beyond its ornamental appeal. Its fragrant flowers attract pollinators like bees and hummingbirds, contributing to garden biodiversity. The dense foliage and vigorous climbing habit make it an excellent choice for privacy screening, covering unsightly fences, or softening walls and pergolas.
While less aggressive than some other honeysuckle species, its vigorous growth requires thoughtful management to prevent it from becoming unruly. Regular pruning, as detailed earlier, is the primary method for controlling its size and spread. Without proper training and occasional trimming, the vine can quickly grow beyond its intended space, potentially overwhelming smaller plants or structures. Provide a sturdy support structure, such as a trellis or arbor, to guide its growth in a desired direction. Consistent monitoring allows for early intervention, preventing the vine from becoming too dense or spreading into unwanted areas.
