Background

Woodbine honeysuckle (Lonicera periclymenum) is the European honeysuckle of hedgerows, grown for the scent as much as the flower: the tubular cream and yellow blooms, flushed red or purple in cultivars like 'Serotina' and 'Belgica', are beautiful, but the fragrance in the evening is extraordinary and carries across a garden. It is a twining woody vine to 15 or 20 feet that needs a fence, trellis or tree to climb.

Plant it with its roots in shade and its top in sun, in rich, moist soil that drains, as at a woodland edge, and water until it is established. Prune right after flowering to control the size and to encourage next year's flowers, which form on the previous season's growth; an overgrown plant can be cut hard in late winter and will take a year to recover. Aphids cluster on the new shoots in spring and the plant shrugs them off.

The flowers are pollinated by long-tongued moths at dusk, which is why the scent is strongest then, and the red berries that follow feed thrushes and other birds. As cut material the flowering tips make a fragrant trailing element in summer arrangements; cut in the cool of the morning and condition them in water at once. Unlike the Japanese honeysuckle it is not invasive in North America, but it does self-sow a little.

Common problems

Powdery mildew

Symptoms

White or grey powdery coating on leaves - usually starting on older growth in humid conditions or when nights cool.

Treatment

Improve air circulation by thinning plants. Apply neem oil or potassium bicarbonate spray at first sign. Avoid overhead watering.

Pests

Symptoms

Clusters of small soft insects on new growth and flower buds.

Treatment

Knock off with a strong jet of water. Ladybirds and lacewings are natural predators. Insecticidal soap as last resort.
