Tibouchina urvilleana, truly a vibrant purple glory bush!

Tibouchina urvilleana

Such vibrant purple blooms of Princess Flower is definitely a sight to behold and a must for gardeners!

Tibouchina urvilleana (Princess Flower, Glory Bush)We first sighted a row of these glorious bushes during our vacation at Cameron Highlands in late October 2013. Simply irresistible and absolutely spectacular! Hence, we bought a pruning shear and took some cuttings home and hoped to root them in a pot.

With great enthusiasm, we watch their steady growth and expectedly it was a great success, rooting easily without any need of rooting hormone. We transplanted only one young plant, the sturdiest of the lot, into a large pot.

Six months later, it started flowering and it has been blooming almost perpetually ever since. Super reliable to keep us delighted everyday! :D
