Sweet Autumn Clematis

Sweet autumn clematis is a vigorous, semi-woody vine with glossy compound leaves and masses of fragrant white flowers. It can reach about 5–9 m tall, and its growth may need containment where it reseeds or roots as it rambles. [Oregon State University](https://landscapeplants.oregonstate.edu/plants/clematis-terniflora) describes its size and flowers; [University of Arkansas Extension](https://www.uaex.uada.edu/yard-garden/in-the-garden/reference-desk/vines/sweet-autumn-clematis.aspx) notes its spread and regional management needs. ## Flowers and placement Use a sturdy trellis, fence, or other support for this climbing vine. It flowers in late summer and may continue into early autumn. Full sun or partial shade and well-drained soil suit it; keep the root area from becoming waterlogged. ## Growth and containment The vine flowers on current-season growth. In regions where it can escape cultivation, assess local guidance before planting and remove seedlings or rooted stems beyond the intended area. Its reach and vigor suit large supports more than small shrubs or delicate structures. ## Maintenance University of Arkansas Extension advises hard pruning from late February through mid-March, with the amount adjusted to the vine’s woody growth and the support available. Watch for self-sown seedlings and contain stems that root as they spread.
