Petrea is a genus of evergreen flowering vines. They have rough-textured leaves, hence the common name sandpaper vine. Dangling from the raceme (hanging cluster of flowers) are dozens of pale purple sepals. Violet flowers grow from the center of the sepals. The sepals serve to attract pollinators to the smaller flower. The flower only lasts a few days but the sepals remain for weeks.
