Tibouchina

These glorious purple flowers dazzle just as the summer-flowering show-offs are tiring. Let’s take a closer look.


Fact file

Name: Tibouchina sp. commonly known as purple glory bush, lasiandra or tibouchina.

Origins: South America

Flowering: Late summer to early winter

A large genus of 350 species of perennials, shrubs and small trees, with hairy, prominently veined leaves, and five-petalled flowers in purple, pink or white. Full sun positions in warm climates with ample water throughout summer are ideal, though they will flower in semi-shade.

Growing 

Now: Velvety foliage is the perfect foil for masses of brilliant flowers.

Winter: Protect from frost and enjoy the last of those lovely flowers. Prune after flowering to keep a compact shape. Keep some cuttings for propagation.

Spring: Increase watering and feed with a flower and fruit fertiliser.

Summer: Water well at least once a week.

We love them

Around period homes in the company of other old-fashioned favourites like Echium, Pelargonium and Raphiolepis. The showy flowers suit tropical gardens too, mixed with Plumeria, Hibiscus, Phormium and Allamanda for year-round colour.

 

Warnings

Protect from frost and strong winds that can damage the brittle stems.

 

What else

They do tend to drop a few leaves so if you’re a neat freak, think twice!
