Large periwinkle (Vinca major)
Many variants of the periwinkle plant are native to Europe and Western Asia. It thrives in North America after being introduced by European settlers in the 1700s. It may be the most polite and charming “invader” North America has seen; it certainly has been given a warm welcome.
“Periwinkle Blue” is the colour most commonly associated with this flower, although selective breeding has developed reddish lavender, reddish violet and white cultivars.
