Petrea volubilis
Also called Purple Wreath, Sandpaper, Queenswreath, Sandpaper Vine
Queen's-wreath is a woody, evergreen vine (or semi-climbing shrub) from tropical America, grown mainly for its long clusters of violet-blue flowers. It needs full sun, good drainage and warmth to bloom well.
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.
In temperate climates, Petrea volubilis prefers full sun and can tolerate shade, although it will not flower profusely. It handles a very light and fleeting frost at temperatures down to -2 °C, but beyond this threshold the plant would die. It thrives in well drained, fertile soils and can tolerate drought.
The Wayapi ethnic group traditionally uses a preparation with sap to treat burns, wounds, inflammation and abscesses, and in the Caribbean it is used to treat diarrhea.
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.
