Clematis

Clematis is a diverse genus of flowering vines and herbaceous perennials, grown for flowers in many shapes and colors. Some climb fences, trellises, or shrubs, while herbaceous forms grow through borders; choose a species or named cultivar to fit the available space and desired flowering period. ([Royal Horticultural Society growing guide](https://www.rhs.org.uk/plants/clematis/growing-guide); [Kew Plants of the World Online](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:329401-2)) ## Choosing a site Most clematis grow in sun or partial shade, but suitable exposure and size vary by selection. Climbing types need support and benefit from cool, moist roots; herbaceous forms suit mixed borders. The genus includes plants with different bloom seasons, so consult the individual plant profile before planting or pruning. ([RHS growing guide](https://www.rhs.org.uk/plants/clematis/growing-guide)) ## Maintenance Pruning depends on when a clematis flowers and whether it blooms on old or current-season growth. Identify the species or cultivar and its pruning group before cutting; a genus-wide calendar can remove future flowers.
