About this plant
These are shrubs with an exotic touch that produce their good size hibiscus flowers in late summer. The flowers, both single and double, come in a good range of colours from white, blue, red, violet and lilac shades. The shrubs themselves are upright with lobed leaves coloured a good rich green shade. They need plenty of warmth to thrive, and are late into leaf, often not leafing out till the end of May or even later. This may provoke anxiety on a yearly basis! They need plenty of moisture and good management to give of their best, so be prepared to prune them each spring to ensure a good crop of flowers. When the flowers do arrive, their fragile, transient beauty is one of the highlights of the late summer garden.

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 in dry periods
Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.
Winter
Winter · Planting
Prune to maintain the plant
The plant is best left largely unpruned. When dormant remove any branches that are dead or diseased. In addition, remove any branches that are awkwardly angled or which grow back through the centre of the plant spoiling its open shape.
