About this plant
A good dark blue flowered herbaceous clematis. This flowers for a good season from midsummer through to autumn when its small but freely produced small clusters of flowers make a pleasing and quiet contribution to the garden. It is in their detail that the similarity of the flowers to those of the hyacinth can be seen. Each little flower has four long, slender, rather oblong tepals (technically petals) that curve strongly backwards to reveal the heart of the flower. They make mounded plants that are attractive in their large, somewhat olive green leaves. The flowers only form a minor element in the display, when viewed from a distance.

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.
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.

Prune Clematis Group 3 - "hard prune" every year
Late and small flowering Clematis (Group 3) "hard prune" late winter or early spring. Start at the base, on each stem find the first pair of good healthy buds, or leaf nodes. Take off all growth above these.
This clematis flowers on wood grown in the current year. It flowers from early summer onwards and is pruned annually to remove all the old growth so the plant produces good young growth which will carry the flowers that year.
