My Manacá this morning. This is a native from São Paulo, where I live.
Flowers open in white, get pink at noon and die purple in the evening, so one gets the three colours at the same time during the day.
from Wikipedia:
"Tibouchina mutabilis is an evergreen tree with an open crown that grows in Brazil , mainly at the Serra do Mar zone.
Also known as glory bush in Australia, where it is a popular ornamental plant.
In Brazil, it is named Manacá-da-serra."
