Clematis maximowiaziana ‘Paniculata’ (Sweet Autumn)

Clematis maximowiaziana ‘Paniculata’ (Sweet Autumn) has 1″ white flowers that are fragrant and it is a profuse bloomer. Clematis ‘Paniculata’, commonly called sweet autumn clematis is a fragrant fall-bloomer. It is a vigorous, deciduous, twining vine with an extremely rampant growth habit. If given support, it will climb rapidly with the aid of tendrilous leaf petioles to 20-25′ in length. Without support, it will sprawl along the ground as a dense, tangled ground cover (to 6-12″ tall and 10′ wide) which typically chokes out most weeds. Features aromatic, 1″ diameter, cruciform, pure white flowers (each with 4 narrow petal-like sepals) in terminal panicles from late August to October in a profuse bloom which typically covers the foliage. Flowers give way to attractive, plume-like seed heads. Compound, leathery-textured, shiny green leaves (3-5 oval to elliptic leaflets with cordate bases). Sweet autumn clematis can aggressively self-seed in the landscape, and has escaped cultivation and naturalized in many parts of the U.S., particularly in the East and Midwest.

Easily grown in average, medium, well-drained soil in full sun to part shade. Unlike almost all other species of clematis, this plant will thrive and bloom well in considerable shade. Blooms on new growth. Prune hard in fall after flowering or in early spring. This vine grows best in a fertile, well-drained, alkaline soil. A choice site is key to the success of establishing this perennial; roots should be kept cool and moist.

General Information +

General Characteristics: Clematis may be planted and trained to cover walls, trellis, posts, fences, arbors or to cover rocky sites. It will need support. Prefers a rich, well-drained soil with a pH of 5.6-6.5. Clematis do best in neutral or slightly alkaline soils, but they are somewhat adaptable. If you have very acid soil, try to add some calcium when you plant. If you want to grow really good clematis you should incorporate a little lime in the planting holes. Roots should be planted in a cool moist environment, while the vine itself should be in the sun. Root area should be protected. They require 1" of water a week. 'Sweet Autumn Clematis' blooms on current season's wood. this fast growing vine will top 20' in one season. It is unusually late blooming for a Clematis, bearing clouds of fragrant, 1', star-shaped, white flowers late Summer into Fall. The sweet vanilla fragrance is wonderful & not overpowering, bringing back the sweet scents of Spring. After the flowers fade, silvery, plume-like seed heads decorate the vine. It's easily and best pruned in late Spring by cutting last year's stems 6-12" above the ground. Don't be alarmed by this drastic pruning – it's so vigorous that by mid-season it will be covering the fence or trellis again. Plant in a sunny, well drained location where its roots can be shaded and cool (a thick layer of mulch works fine). Deciduous to semi-deciduous.

Use: Trellises, arbors, posts, fences. Can also be allowed to sprawl along the ground as a dense ground cover to hide old tree stumps or other eyesores. Can also be grown through large shrubs, but growth must be monitored to insure that the shrub is not overwhelmed.
