Many of you probably know about, or even have in your garden, this gorgeous plant that has blue flowers beyond belief.
My two plants are old; have become big & straggly. I've been afraid to prune, because my gardener told me years ago that if pruned, they will not regrow.

With the large (2") passionately purple flowers and felt-like leaves this Princess Plant is an attention grabber. Tibouchina urvilleana blooms almost constantly through the spring to frost. Princess Plant goes winter deciduous for me even in frost free locations. I cut Tibouchina urvilleana back at during the Winter to pencil sized wood as most of the smaller branches die anyway. Tibouchina urvilleana is a coastal gem. It also thrives in the banana belts of the inland valleys if they are well enough protected. Heat and humidity are both helpful for Tibouchina urvilleana. The Princess Plant dies back if temperatures drop into the 20's and way back in the low 20's. Unfortunately the recovery from the cold is miserably slow. The biggest Princess Plant that I have seen is 12' tall and wide. Tibouchina urvilleana prefers loamy well mulched soil.
