A native of Brazil, the princess flower (Tibouchina urvilleana) is a glorious addition to tropical and sub-tropical gardens. This broadleaf evergreen has large purple flowers and soft hairy leaves that add interest and a burst of color to any landscape. Though princess flower is usually grown as shrub in the U.S, it sometimes becomes large enough to form a small ornamental tree. It can also be used as an indoor container plant in cooler regions if full light and warmth are provided.The leaves of princess flower are 2 to 6 inches in length and 1 to 1 1/2 inches wide, covered in soft hair and often tipped with red around the edges. The flowers are 3 to 5 inches wide and a deep, vibrant purple. Princess flower can produce blooms year-round, especially if it is deadheaded to encourage the formation of more flower buds. The fruit is a small brown capsule that is less than 1/2 inch long.Use the princess flower as a specimen plant or for borders and foundations. The large vibrant purple flowers and soft hairy leaves work well in sensory gardens. This shrub is a recipient of the Award of Garden Merit given out by the Royal Horticultural Society.
