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, with prominent veins that are puffed up in the middle 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. 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. 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 on this page is based on research conducted in our nursery library and 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 that we have observed it in. We also will incorporate comments received from others and always appreciate 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 that might aid others in growing Tibouchina heteromalla.
