About this plant
This is the ultimate cultivar of Cornus alba for winter colour as vivid as fire. The colour darkens as winter draws to an end and makes the requisite hard spring pruning less difficult to accomplish. The young stems flash bright and immodest through the summer green of the leaves. Insignificant flowers are sometimes followed by bluish fruits. The leaves turn scarlet and dangle, brilliant as the stems before they fall in mid-autumn. Then it's back to months of winter glory. This plant has leaves that are quite plump, shorter and broader than the species. Less robust, it needs fertile damp soil to give of its best. If possible this should be placed where the winter sunlight hits the stems from the front. Out of season it is a good background shrub for perennials. If left to its own devices it will sucker and gradually form a large foliage clump.

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.
