Petrea volubilis, commonly known as purple wreath, queen's wreath or sandpaper vine, is an evergreen flowering vine in the family Verbenaceae, native to Tropical America, that is valued especially for its display of violet flowers.

Description

As a climbing plant, it grows to a height of 12 m (39 ft), but as a shrub it grows to 4 m (13 ft) tall. It is a vine or semi-climbing shrub with puberulent stems, sometimes reaching 10 cm (3.9 in) in diameter. Leaves are elliptical-oblong, 5–16cm long and 3–8cm wide, apex acute or obtuse, base wedge-shaped, entire margin, sometimes sinuous, glabrous or pubescent, rough to the touch; petiole 0.2–1 cm long.

The flowers emerge from bracts. Racemose inflorescences 8–20 cm long, axillary or terminal, solitary, puberulent rachis, 5-mere flowers on puberulent pedicels supported by a deciduous bract ; calyx tube 0.2–0.7 cm long, glabrous or puberulent, corolla infundibuliform, 1 cm long, puberulent, blue; ovary and glabrous style. Drupaceous fruit completely enclosed in the acrid calyx which acts as wings or floats.

Distribution and habitat

It is found especially on the banks of rivers and streams, from northern Mexico to Bolivia, Brazil and Paraguay in the Antilles and in Venezuela. Depending on the climate, it can have up to two blooms in the year. Its very nectar-bearing flowers attract butterflies.
