Light Requirements. Both greater and lesser periwinkle will grow in full sun, but they prefer some shade. Vinca major prefers to grow in partial shade but will even tolerate deep shade. The light conditions in which vinca grows, however, affect the performance of the plant.
Do periwinkles come back every year?
While both plants are separate species within the genus, they have a lot in common. Periwinkles spread rapidly, providing excellent groundcover and erosion prevention. Prolific reseeding habit guarantees the plant’s return in spring, even in bitter climates that kill it back completely.
Where should I plant periwinkles?
The periwinkle plant grows best in a partially shaded area in acidic soil; however, it can thrive in a variety of sunlight and soil conditions. Growing periwinkle in partial shade creates more vigorous growth. In many instances, extreme vigor may not be desirable unless the periwinkle plant needs to cover a large area.
