About this plant
This is a rather open habited shrub with long leaves, matt and coloured green. They are carried on shoots which are red and hairy when young. The flowers are held in short, quite dainty panicles, open cone shapes, and come in various colours from violet to orange and cream shades. They are likely to be present all through summer. They are slightly fragrant though, seemingly, not all can detect this. Grow this against a warm wall. It is found growing naturally across a wide area including India, Burma and Yunnan province in China. It can be pruned for containment and grown in a container, brought under cover for winter.

Spring
Spring - late · Outdoors
Feed with slow release fertiliser
Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming 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 during dry periods
For plants in the ground, when there has been little or no rain for a period of 7-10 days and the soil is dry, give it a deep watering and repeat weekly until there is a downpour of rain. Check plants in pots more frequently, especially in hot weather.
Spring - early · Planting
Prune hard to the base
Prune back to within 30cm to 45cm of the plant base so that the year's growth will begin from this low framework. If you want the plant to grow larger, this need only be done every few years.
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.
