About this plant
A clematis bred in Japan, the name is said too mean 'White royal crown' which must describe the upright fan-shaped array of Jersey cream stamens that sit at the heart of its flowers. The flowers are normally single and are coloured a warm and gentle shade of purple with slightly red-mauve lines running down the central area of the petals (technically tepals). There may occasionally be some semi-double flowers. Yellow seedheads follow the flowers. This flowers from late spring to early summer with more flowers in August. This is group 2 pruning.

Spring
Spring - late · Outdoors
Feed with slow release fertiliser
Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)
This is a simple way to provide a nutrient boost as a single annual procedure.
Spring-Autumn · Outdoors
Water to keep the soil moist
For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.
Without regular watering some plants never fully regain their beauty.
Spring - early · Planting
Prune Clematis Group 2 - prune to a framework
Early to mid-season Clematis (Group 2) tie onto supports, shorten long shoots, pinch out tips and tie in. Remove dead, diseased, damaged growth. When mature (after 2 years) take out any weak growth to the ground and cut shoots back by a third to buds.
Summer
Summer-Autumn · Planting
Support young plants
Provide support for young plants, and tie in any growth to the support to keep it tidy.
Winter
Winter - late · Outdoors
Apply an organic mulch
Apply an organic mulch to the plant taking care not to bury its stem or cover any young growth that emerges from its centre.
A mulch is a covering that can: protect the soil surface from rain, heat and cold; deter weeds; provide nutrients. Organic indicates that material has vegetative origin e.g. manure, compost. Synthetics i.e. plastics, or stones are often called mulches.
