Periwinkle, scientifically known as Vinca minor, is a trailing evergreen ground cover that is valued for its glossy green leaves and delicate, star-shaped flowers. Here is a description of Periwinkle along with care guidelines: Habit: Periwinkle has a spreading and trailing growth habit, forming a dense mat of vegetation. It typically grows to a height of 4-6 inches, but its trailing stems can spread much farther. Leaves: The opposite, oval to lance-shaped leaves are dark green and have a glossy appearance. They are about 1 to 2 inches in length. Flowers: Periwinkle produces small, tubular, five-petaled flowers that come in shades of blue or purple. The flowers are solitary and bloom in the spring. This plant will not begin to grow until the following spring. It is shipped bare-root and dormant (has no leaves or foliage). Periwinkle is a versatile and resilient ground cover that adds beauty to shaded or woodland areas. Cannot ship to: OR. WI. DE.
