About this plant
This is usually seen as a compact shrub with a dense growth habit. It has small dark green glossy leaves that are close-packed on the branches. In early summer it produces small clusters of urn flowers, these have pink flushing over a whitish base. They are often tucked into the leaf axils and may be borne singly, in which case they scarcely notice as the foliage may cover them. The dark purple or black fruits that follow are edible. It may need trimming in late summer when it sends out long wayward branches if its well-ordered, compact growth habit is to be retained. This comes from the Yunnan in China where it may grow as an epiphyte on aged trees. It likes acid soil and is not reliably hardy across the whole country.

Spring
Spring · Outdoors
Apply acidic mulch
Where soil is only just acidic, apply mulch with a high acidic content such as leaf mould, or mulch for ericaceous plants. Alternatively the plant can benefit from a feed of iron supplement (iron chelate) such as sequestrol.
Spring-Autumn · Outdoors
Water in dry periods
Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.
Spring-Summer · Planting
Prune lightly after flowering
Give the plant a light haircut, generally tidying it up and removing any shoots that are wayward or damaged in any way. Dead flowers can be cut off if this is practical - the shrub may have too many, or they may be hard to reach.
Summer
Summer - early · Outdoors
Apply slow release fertiliser
Apply a slow release fertiliser which is spread around the root area of the plants soon after they have come 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.
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.
