Petrea volubilis is a stunning tropical climbing vine admired for its cascading clusters of star-shaped purple flowersthat resemble wisteria. Known as the Sandpaper Vine for its rough-textured leaves, it makes an exceptional ornamental, ideal for pergolas, fences, and trellises.
Often called the “Queen’s Wreath”, this vine provides year-round beauty in warm climates and is especially striking when in full bloom, creating a waterfall of vibrant purple.
