About this plant
If well grown this can form a handsome plant. It is a good sized, rather elegant, shrub with spreading, sometimes slightly tiered, branches. The leaves are wavy edged and bright green with an irregular golden blotch at their centre. The leaves are paired on the stems which adds to the effect. In May and June there are rounded white flowers and, in autumn the centre of the leaf turns yellow whilst the leaf margin takes on purple hues. It does best in acid soil though it can tolerate slight alkalinity if there is always plenty of moisture available. It needs a sunny or partially shaded spot in fertile soil that is well drained but has some moisture in it. This reaches around 5m (16ft) height with 3m (10ft) spread.

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 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.
Winter
Winter · Planting
Prune to maintain the plant
The plant is best left largely unpruned. When dormant remove any branches that are dead or diseased. In addition, remove any branches that are awkwardly angled or which grow back through the centre of the plant spoiling its open shape.
Planting & general
Outdoors
Water with rain water
This plant needs rain water or soft water (the minerals in alkaline or "hard" water are harmful). This is especially important for plants in pots.
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.
Compost · Planting
Ericaceous compost
This plant requires acidic (ericaceous) soil. Where the soil is not acidic, or when planting in pots, use an ericaceous compost.
