About this plant
An upright shrub that carries good-sized dark green leaves with paler midribs. They are lustrous, of ample appearance, rather lush-looking for a hebe. The plant flowers from July producing good sized cone-shaped heads of bloom. These are coloured blue-purple. Close examination reveals pinkish anthers, the colour complementing the pinkish young stems. If deadheaded regularly this will repeat flower into autumn. An excellent background shrub that could possibly be combined with some of the smaller Buddleja forms. It is unlikely to be hardy in cooler parts of the country and may need winter protection.

Spring
Spring - late · Outdoors
Apply slow release fertiliser
Apply a slow release fertiliser which is spread around the root area of 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.
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.
Spring - mid · Planting
Prune old branches occasionally
On well established plants, every other year take out two or three branches to their base, doing this as the plant is just coming into growth. This is a very gentle prune, and be careful not to spoil the plant's symmetry.
Summer
Summer-Autumn · 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.
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.
Planting
Deadhead blooms during flowering season
Remove flowers as they turn brown and fade. Snip the stem just below the bloom. This will keep the plant tidy and encourage more flowers.
The removal of spent flowers encourages the plant to produce fresh ones, rather than spend its energy on the development of seeds.
