Hibiscus syriacus, Rose of Sharon, is a hardy, deciduous shrub to around 3 metres tall and wide, with trumpet shaped mauve flowers with a contrasting purple-red eye. There are many cultivars of this plant, from white to deep pink colours, and some semi double blooms. This is a hibiscus that can be grown in cooler areas, as it is a cold hardy plant. It blooms continuously through the warm months. Use as a feature plant, for massed plantings, and is great for container growing.
Hibiscus like a sunny position, and fertile, well drained soil. Fertilise in spring and autumn, and water regularly. Hibiscus don't like to grow in boggy conditions. Hibiscus syracius can become leggy and sparse, prune hard to encourage dense growth.
The fibres of hibiscus bark can be used to make grass skirts. The flowers are edible, and can be used to make tea.
