The periwinkle (Vinca) or the violet of sorcerers :
The periwinkle is a plant widely used as a ground cover, thanks to its persistent foliage and its flowers rich in color. It adapts perfectly to the shade, but without regular size can become invasive. Counting different species, Periwinkle Vinca is recognizable by its flat flowers with five petals, sometimes violet, white, pale pink, or purple.
The light green leaves are small and smooth and the stems are around 15 to 30 centimeters depending on the variety. In addition to its decorative qualities, be careful because all parts of the plant are toxic and likely to cause vomiting if swallowed.
