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.  Information on this page is based on research conducted in our nursery library, from online sources, as well as from observations made of this plant as it grows in our nursery, in the nursery's garden and in other gardens where we have observed it. We also will incorporate comments received from others and welcome getting feedback of any kind from those who have additional information, particularly if this information is contrary to what we have written or includes additional cultural tips would aid others in growing Tibouchina heteromalla.
