T. granulosa can be distinguished from other Tibouchinas by the grainy texture on the underside of the leaves.
08/04/2008 update: I have now been growing T. granulosa in my home garden for about one year, along with three other Tibouchina species (T. urvilleana, grandiflora, and heteromalla). T. granulosa seems to be the most cold hardy. It showed little damage from winter temperatures that went as low as about 28 F on several nights for several hours, whereas the other three Tibouchina species had significant freeze back (but recovered in spring). T. granulosa also seems to be the easiest to grow in my climate, tolerating hot and humid temperatures, and periods of drought and heavy, frequent rains. A big advantage I've found is that the lubber grasshoppers don't seem interested in eating T. granulosa, but they will strip T. urvilleana and heteromalla of all their leaves if the grasshoppers are left on the plants.
