What is a periwinkle shell?
The periwinkle is a small snail that is easily found on rocks or pilings in the intertidal area. A young periwinkle's shell has ridges and an adult's shell is smooth. They are generally about ½” wide and 1” long and are brown, black or gray and blend in with the rocks.
Why is periwinkle called flower of death?

How do periwinkles breathe?
It feeds on algae by scraping the rock surface with its radula or tongue. The rough periwinkle can survive for extended periods of time with little to no oxygen, using anaerobic metabolism to obtain energy. It also has a lung-like organ, similar to land snails, that allows it to breathe air directly.
What do periwinkles turn into?
Gradually they grow a shell, transform into tiny periwinkles, and settle to the bottom of the subtidal zone. According to the literature, periwinkles then move up into the intertidal zone and become sexually mature within 18 months. During these months periwinkles can grow to be 18 millimeters in shell height.
Can you keep periwinkles as pets?

What does a periwinkle eat?
Common 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.
How are periwinkles born?

How do I grow periwinkle?
Space plants at least 12 to 18 inches apart. Plant out periwinkle in spring or early fall.
