Akebia quinata
The chocolate vine is a vigorous, twining climber with graceful five-lobed foliage and unusual chocolate-purple flowers appearing in April and May. The blooms release a subtle, sweet fragrance reminiscent of chocolate and vanilla. In warm weather, striking pear-shaped fruits may develop.
Plant in sun to partial shade in any well-drained soil. The plant grows vigorously and needs a sturdy support structure. Water regularly in the first season. Feed lightly with compost in spring.
Prune after flowering to keep growth in check. The plant can become very vigorous and needs regular maintenance. Remove dead and tangled stems in late spring. In winter you can prune hard if the plant has become too exuberant.
Wisteria sinensis
Chinese wisteria is a vigorous climbing plant that produces spectacular hanging flower clusters in spring. The fragrant purple, blue, or white blooms appear before the foliage has fully unfurled. A mature plant can completely cover walls and pergolas with a lush canopy of leaves.
Clematis montana
Mountain clematis is a fast-growing climber that becomes smothered in white or pink flowers during May and June. The plant can cover large surfaces in a short time, making it ideal for growing over pergolas, fences, and unsightly walls. The lightly fragrant blooms appear on the previous year's wood.
Lonicera periclymenum
Honeysuckle is a native climber with clusters of two-lipped flowers in yellow and pink that release a delightful honey-like fragrance from June to September. The scent is strongest in the evening and at night, attracting moths. In autumn, glossy red berries appear.
