Brazilian natives with showy flowers at branch ends and broadly oval, prominently veined, velvety leaves. Prefer slightly acid, fastdraining soil. Protect from strong winds, hard frosts. Pinch young growth to induce branching; prune out damaged or badly placed branches before new growth begins. If flower buds fail to open, check for geranium (tobacco) budworm.Tibouchina urvilleana
The only species widely available. Fast, rather open growth to 5–18 ft. tall, 3–10 ft. wide. Branch tips, buds, new growth shaded with satiny hairs in orange and bronzy red. Green, 3– 6-in.-long leaves, often edged red. Older leaves add spots of orange, red, or yellow, especially in winter. Brilliant royal purple, 3-in. flowers appear intermittently from late spring into winter. Prune lightly and feed after each bloom cycle. Has naturalized in Hawaii, forming thickets in wet areas. Can be used as indoor/outdoor plant in colder climates. Can be grown in Zones 14 and 15 with protection.
