Tibouchina heteromalla (Silver leafed Princess Flower) - This evergreen shrub has an upright growth habit to 8-10 feet tall with velvety silver-green 4-6 inch long leaves that have prominent veins and old leaves will often turn a beautiful orange color just prior to dropping off. The 1 1/2 inch wide violet flowers on long spikes bloom mid-summer and last until fall. Loves full sun and moist soil during the growing season but tolerates regular to only occasional irrigation in our coastal gardens. In hotter inland areas some afternoon shade is beneficial. It has proven hardy in our nursery garden to 30 F with only slight young growth tips being damaged. In our January 2007 cold snap with temperatures to 25 F several nights this plant was frozen back but rebounded by the following year. Cutting back plants occasionally helps maintain good form as it does get a little top heavy and spent flower stems are best removed in the fall, lest they detract from the beautiful foliage in winter and early spring and tip pruning for shape should be done in winter to early spring to not interfere with later summer flowering. Tibouchina heteromalla is endemic to Brazil, where it occurs in rocky areas in small scattered populations in the southern area in the state of Minas Gerais. The specific epithet is a combination of the Greek words 'heteros' meaning "other party" or "another" indicating dissimilarity and 'mallos' which means "wool" in reference to the different types of hairs on the leaves of this species. This plant is sometimes sold as Tibouchina grandifolia. Another common name for this plant is glory bush.  The information that is presented on this page is based on research we have conducted about this plant in our library and from reliable online sources. We also consider observations we have made of it in the nursery's garden and in other gardens we have visited, as well how it performs in our nursery crops out in the field. We incorporate comments that we receive from others as well and welcome getting feedback from anyone who may have additional information, particularly if they know of cultural information that would aid others in growing  Tibouchina heteromalla.
