Tibouchina heteromalla (Silver Leafed Princess Flower) is an upright, tropical, evergreen shrub boasting velvety silver-green, broad ovate-cordate leaves, 6 in. long (15 cm), with silver undersides. The old leaves usually turn a warm orange color just prior to dropping off. Blooming in summer and fall (depending on geographic location), ravishing rich violet-purple flowers, 1.5 in. across (4 cm), appear on long spikes. Each flower spike can reach 18 in. in height (45 cm) and be adorned with many blooms. It is a very ornamental species thanks to the big leaves with a silky surface and to the showy flowering which lasts several months.
