Petrea volubilis

Queen’s wreath
Verbenaceae
Evergreen, Vines

Woody vine native to Mexico, Central America, and the West Indies. Twines to 20–40 ft. but can easily be kept smaller. Elliptical deep green leaves to 8 in. long have a sandpapery surface. Stunning floral display: pendent, foot-long clusters of star-shaped, blue-purple, 1 1/2-in.-wide blossoms. Blue calyxes hang on after the petals drop. Main bloom period comes in winter and spring in Hawaii, late spring and summer in California; lesser displays occur at other times during warm weather.

Beautiful plant trained on an arbor or a pergola, along eaves, or on a high wall. Flowers are sometimes used in leis. Grow this vine in organically enriched,moist but well-drained soil. Provide support for climbing stems. Prune and thin growth as needed in winter. Wind resistant. Frost sensitive.
