What is this tree?

Does anyone know the name of this bush/tree?   All around the suburb I am staying in there are these beautiful trees!  I would love to have one in Washington DC – I wonder if they would survive the frosts & ice?

  1. I have one! TIBOUCHINA! I have the Alstonville.

    The Tibouchina is a fabulous plant. Some to look out for include Tibouchina ‘Kathleen’, with its beautiful, mauve-pink flowers. Another that’s popular is Tibouchina mutabilis ‘Noelene’ – the flower starts white and turns to a mauve-pink. It mutates hence the name – mutabilis. And Tibouchina lepidota ‘Alstonville’ is covered in masses of purple flowers from autumn right through to winter. It's called Alstonville because it was developed in Alstonville in northern New South Wales. The plants filmed by Gardening Australia are in a garden in the hinterland of the Sunshine Coast where the soil is acidic – absolutely ideal for Tibouchinas. If the soil is not acidic enough the leaf burns at the edges, turns brown and eventually the leaf dies. If that happens correct the soil acidity by adding sulphur on the ground, around the roots, or use an acidifying fertiliser. Tibouchinas originated in South America, where they grow over a wide diversity of climates, and that means they'll do the same in Australia. They don't like hard frosts, but give them a warmish spot and they'll do well from Melbourne to Cairns.They do need pruning, otherwise they will grow into a fairly large tree. Afer they finish flowering, prune the plant back. Delaying the pruning means you throw the whole flowering season out of kilter and this will result in spasmodic flowering.Tibouchinas do well because there's not a pest or disease that comes near them. If you've got one I’ll guarantee you'll be thrilled to bits.

  2. The colours are spectacular. I was taking these photos basically at midday so the actual tree one is a bit washed out. As you drive along there are many of these trees and they seem to be more flowers than leaves.

  3. Wow!! Thank you for all that info! It seems you can help more than just me with this! At least now I can look for one in the States. Interesting about the pests/diseases – I wonder why that is.
