This evergreen sub-shrub is somewhat vine-like, but it will not climb. It grows 4-8 in. tall and creeps on indefinitely. Periwinkle has been hybridized and now may have white, blue, violet or purple flowers from June to September. It grows in full sun to full shade, any soil, and likes water 1-2 times per week. Useful under trees, on slopes, or as a groundcover in low traffic areas. This plant is not bothered by rabbits, squirrels nor deer. (Plant 4 ft. on center)
