Tibouchina 

Tibouchina – Tibouchina sp. roadside, Eagle Heights. 

The powerlines were in place long before the then owner of the house planted this row of trees, which I filmed more than twenty five years ago. 

They have been regularly pollarded since, but I have never seen them looking so well as in early April. 

I suppose tibouchina are the autumnal equivalent of Spring’s jacaranda. Both species are endemic to Central and South America.
