About this plant
The lovely flowers of this form have an exotic and refined air. The plant is in fact not especially hardy and is only really suited to living out of doors all year in the warmest parts of the country. Its modest height means it can be grown in a large container and brought inside for the winter. It is worth it because the flowers are so delectable. They are coloured creamy white with a pale green slim line at the centre of the outer petals (the tepals). The central areas of the flower are actually modified stamens that are sterile and form a showy centrepiece with a green bud like structure at the centre. All this gradually opens in a confusion of petals. This comes into flower in early summer and should go on till early autumn. It needs plenty of moisture and a sheltered spot. It is in Clematis pruning group 2.

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.
