Identifying Greater Periwinkle

Sometimes apparently simple flowers can turn out to be some of the most beautiful. They tend to go largely unnoticed against spectacular garden cultivars in the summer. Your appreciation for the simplest flower is renewed in winter when there is little else around. The Greater Periwinkle (Vinca major) is just such a flower with 5, partially fused petals that remind you of a windmill or propeller.

Distinguishing Hairs Visible with Hand Lens

The identification of other distinguishing characteristics requires a hand lens. You should then be able to see tiny hairs on the sepals (above) and on the edges of the evergreen leaves (below). These hairs are absent on Lesser Periwinkle, Vinca minor.
