About this plant
When discovered, this was thought to be a form of viburnum. It is a low growing, rather dense plant. The leaves are held rather sparingly on the dark coloured stems. They are coloured a dull matt green, held somewhat horizontally. Their edges are toothy and they are hairy to the touch. There is a certain quiet elegance in the appearance of this shrub. It comes into flower in the summer, presenting dome shaped flowering clusters that are most commonly coloured blue but which may also be pink or white. They are said to be fragrant. The flower heads turn brown and remain a quiet feature during the winter months. It is unlikely to exceed 1.5m (5ft) in height and will often be far less. It is likely to have a spread of around 1.2m (4ft)

Spring

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 - 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
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.
