Tibouchina Noelle, the most glorious flowering tree.
Please click the pictures
Tibouchina Noelle can be grown as tree or shrub. I have left it to grow into a tree probably around 5m high. The trunk is a wonderful host for orchids. Many different lichen have also taken this tree as host to display there wonderful patterns.
Believe it or not:
"Carefree" refers more to the plant's attitude than to your workload.
