Description

Tibouchina heteromalla reaches an average height of 4–6 feet (1.2–1.8 m), with a maximum of about 8–10 feet (2.4–3.0 m) in its native habitat. The branching stem is woody and the large, silvery green leaves are simple, ovate, velvety in texture, and oppositely arranged. The inflorescence is a panicle of several purple flowers with five petals. The plant has 4–6 inches (10–15 cm) 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. [6]

Cultivation

The plant is cultivated as an ornamental for its showy foliage and purple flowers. It is sensitive to cold but can tolerate a light frost.
