European Honeysuckle
Lonicera periclymenum
European honeysuckle is a vigorous deciduous twining climber native across much of Europe, North Africa, Turkey, and the Caucasus, valued for its intensely night-scented cream-and-pink flowers in summer and the wildlife value of its red autumn berries. In gardens it is a reliable, long-lived focal point for fences, pergolas, and trellises where its base can be kept cool and shaded. The honest catch is the toxicity of the berries: they contain saponins and are emetic, making the plant a hazard wherever small children or dogs have unsupervised access, so site it accordingly.

Flowers are pollinated chiefly by night-flying moths (notably nocturnal hawkmoths drawn to the strong evening fragrance) and by long-tongued bumblebees; the night scent is a moth-pollination adaptation.
