Pleroma semidecandrum, synonym Tibouchina semidecandra,[1] the princess flower, glory bush, or lasiandra,[citation needed] is a flowering plant in the family Melastomataceae, native to southeast Brazil.

The dark green, velvety, four to six-inch-long leaves have several prominent longitudinal veins instead of the usual one, and are often edged in red.

Large, royal purple blossoms, flaring open to five inches, are held on terminal panicles above the foliage, creating a spectacular sight when in full bloom.

Princess-Flower is ideal for the mixed shrubbery border or used in small groupings to compound the impact of bloom-time.

Plant in most soils with good drainage and a slightly acid mix is even better.
