Most commonly, the periwinkle you will find in a garden center is Vinca minor. This is the hardier and smaller plant of the two main species—minor in Latin simply means smaller. The other species commonly found is Vinca major. As you may guess, major means bigger. Vinca major is an overall larger plant, with bigger leaves, flowers, and habit.

The flesh will be stuck to a small, perfectly round piece of armor, the periwinkle's last defense against the outside world. Find that circular piece of shell, and use a toothpick or the tip of a pointy chopstick to scoop out the meat. And there you have it: the somewhat complicated, though not time-consuming way of getting at periwinkle meat.

During dry periods, the periwinkle draws into its shell and closes its operculum (trap door) — this keeps its gills moist, and also keeps fresh water and dry winds out. A periwinkle secretes a mucous glue that holds its shell to its rocky home. Adult eroded periwinkles can survive in this mode for extended dry periods — up to 17 weeks.

Apr 21, 2021Common periwinkles are herbivores, using their file-like tongue, the radula, to feed on diatoms and algae attached to intertidal rocks. The common periwinkle breaks down its food by mixing it with mucous on the radula before bringing the food into its mouth. Sea stars, whelks, and some fish eat common periwinkles.
