About this plant
This is a shrub in the UK but may reach the proportions of a small tree in its Himalayan homeland. It has lance-shaped leaves that are coloured mid-green, slightly glossy and veined, and reddish brown twigs. There are handsome flowers in June. These are pendulous, coloured carmine red and look lush, rather like the flowers of a big weigela, composed of individual columnar flowers. This is quite a tender plant and suited to mild sites, especially when young. It is a good candidate for a warm wall.

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.
