It has small, glossy, ovate, dark-green leaves, and clusters of small red or pink, tubular flowers that appear in June - July.
Subject to variety it will grow from 1.5m (5ft) to 5m (16ft) making it a useful subject for forming a hedge.
It does not need much in the way of pruning other than to remove spent flowers.
If grown as a hedge it can be pruned quite hard to maintain a desired height and shape but this will reduce its flowering ability.
It prefers a sunny sheltered spot and will tolerate most types of soil providing it is well drained.
In cold areas it should be offered the protection of a south facing wall or fence.
Week 18: Plant out rooted cuttings.
Week 20: Pot up rooted cuttings into 100-125mm (4"-5") pots of Ji2 potting compost (or equivalent) and grow on in a coldframe till planting out time the following year.
Circa week 32: Remove flowering growths after the have ceased flowering.
Now is also a convenient time to take 75-100mm heel cuttings.
Offering some bottom heat circa 13-16°C ( 55°-60°F) will encourage speedier rooting.
Once rooted pot up cuttings into 75mm(3") pots of Ji2 potting compost (or equivalent) and grow on in a coldframe throughout the winter.
Week 40 - Week 13: Plant out if not done the previous April.
If being grown as a hedge plant out plants when they are around 300mm (12") tall.
Once planted remove the top 25% of the plant to encourage bushier growth.
