About this plant
This is most commonly seen in its colourful cultivars where good stem colour is united with colourful or interesting foliage. However, the species, when well sited, has striking winter colour. It makes a large fairly slender branched shrub with red winter shoots, noticeable on the youngest growth. The leaves, which can measure as much as 12 cm are green all season but take on pleasing red and yellow tints before leaf fall. There are little dome-shaped clusters of white flowers which are followed by round berries, white, or white suffused with blue. It can be grown on a single stem like a tree or as a shrub where it will produce suckers to make a clump.

Autumn - late · Outdoors
Apply mulch
Spread organic material around the plant being careful not to bury its crown, or to put the mulch above the point at which the plant has been grafted in the case of trees.
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.
Spring
Spring - late · Outdoors
Feed young plants with slow release fertiliser
Spread a slow release fertiliser around the base of the plant to the edge of the foliage spread, so that it can feed the roots. It is helpful for this to be applied for several years.
This is a simple way to provide a nutrient boost until the plant becomes well established.
Spring-Autumn · Outdoors
Water frequently to keep the soil moist
The plant thrives in moist or boggy soil, doesn't tolerate dryness and should be watered frequently, not only after a period of drought, but if the soil begins to dry out spring to autumn. Check plants in pots more frequently, especially in hot weather.
Spring - early-mid · Planting
Prune hard to the base
If grown as a shrub for its coloured stems, the plant can be pruned back to a framework that is within 30cm of the ground. Two or three buds should be left so that the plant can produce long brightly coloured young stems.
Planting & general
Outdoor planting · Planting
Add root growth stimulant to the planting hole
Mycorrhizal fungi helps roots establish quickly, so they absorb water and nutrients more efficiently. It comes as a powder, granule or gel. Add to the planting hole or container, and to the plant's rootball before planting in the hole. For "bareroot" plants use a gel.
