Growing it

Propagation: cuttings, layering, seed
When to plant: spring, autumn
Overwintering: Cut back deciduous types in late winter or early spring according to their specific pruning group. Mulch the base well to protect the roots from extreme cold.
In containers: Clematis grows well in large pots, provided you use a container at least 45 cm deep with a sturdy trellis.

Stem cuttings

Take a cutting with two sets of leaves in late spring.
Remove the lower leaves and dip the end in rooting hormone.
Place in a pot with moist, well draining soil.
Cover with a plastic bag to maintain humidity.
Keep in bright, indirect light until roots form.

Plant a low growing perennial at the base of your clematis to shade its roots, as they prefer cool, moist soil while the foliage enjoys the sun.

Grows well with
