Culture Notes

This clematis will grow best in full sun to light or open shade. Provide a location with rich well-drained soil where it can be regularly watered during dry weather. Plant vines that are well rooted and at least two years old. In our climate planting too deeply can smother the roots, especially in heavy soils. Set young plants at the same depth they were in their nursery pots. Clematis are heavy feeders and appreciate fertilizing in spring. This clematis blooms on old stems and on new growth, so it is best to only prune lightly in late spring to early summer once the first flush of flowers have finished. Remove congested or tangled growth and thin to the strongest stems. Well established, overgrown plants can be cut back to 12 inches tall in winter to remove large tangles, allowing robust new stems to fill out the plant, but it will not flower the next year.
