Sweetly scented, Clematis paniculata (Sweet Autumn Clematis) is a very large deciduous climber with masses of starry creamy-white flowers, 1 in. across (2.5 cm), from late summer to fall. The blossoms are so profuse that they generally cover the leathery dark green leaves. Their delightful fragrance, a mixture of sugar, honey, and vanilla, fills the air as you pass by. Even after flowering is over, this vine remains attractive, thanks to the silvery seedheads left by the passing flowers, therefore providing winter interest. Adding charm, fragrance and color in the late season garden, this vigorous and extremely floriferous vine is perfect for covering a wall, fence or arbor.
- Thrives in moist, well-drained soils, in full sun or part shade. Ideally, Clematis prefer having their 'heads in the sun and their feet in the shade'. Keep the roots cool and shaded by other plants or add a layer of pebbles or flat stones at the base.
- Quickly grows up to 20-30 ft. long in a few seasons (6-9 m).
- This Clematis belongs to the third group of Clematis - a group including Clematis which flower in late summer on growth made in that season. They should be pruned in late winter or early spring and require 'hard pruning': simply cut back the stems to a pair of strong buds about 1ft. (30 cm) above ground level before growth begins in early spring. Cut back immediately after bloom where self-sown seedlings are a problem. Sweet Autumn Clematis can grow quite vigorously to the point of being invasive in warmer areas of the country.
- Native to New Zealand
