Queen's Wreath (Petrea volubilis): The Spectacular Purple Vine

Queen's wreath, also known as bluebird vine or sandpaper vine, is a vigorous, woody climber that produces stunning, grape-like clusters of star-shaped, violet-blue flowers in spring and summer. The rough, sandpaper-like leaves give it one common name. Native to the Caribbean and Central America, Petrea volubilis creates a spectacular floral display on pergolas, fences, and arbors.

Cultivation and Support

Provide strong support for its heavy, twining stems. Full sun to partial shade, well-drained soil. Water regularly until established, then it's moderately drought-tolerant. Prune after flowering to control size and encourage new growth. In zones 9-11, it's evergreen; cooler zones may see dieback.

Design Ideas

Train over arches, along walls, or up large trees. The flower clusters are long-lasting and fragrant. Combines well with bougainvillea or passion vine for sequential bloom.
