Periwinkle is a perennial evergreen known for its glossy, oval leaves and charming, five-petaled flowers that typically bloom in hues of blue, white, or purple. Originating in Europe, this plant has become popular worldwide due to its hardiness and low-maintenance nature.

Vinca minor and Vinca major can be grown in a wide range of USDA hardiness zones. Generally, Vinca minor is hardy in zones 4 through 9, making it suitable for many climates, including colder regions. On the other hand, Vinca major is more suited to warmer climates and is typically hardy in zones 7 through 9.

It’s important to note that while periwinkle is adaptable to many environments, its growth habit and health can vary significantly depending on the specific conditions of each zone. In colder zones, it may grow more slowly or require protection during extreme winter conditions, whereas in warmer zones, it might spread more aggressively.
