Vinca–commonly called periwinkle–are slender stemmed evergreen subshrubs and perennials that bear lavender blue, five-petaled, pinwheel-shaped flowers above shiny dark green oval leaves.

Vinca is a useful groundcover for a woodland garden, shrub border, or shady bank. There are two commonly grown species, Vinca major and Vinca minor. Vinca minor has smaller leaves and flowers and a nearly mat-forming ground cover. Vinca major has larger leaves and grows taller; it can be invasive if left unattended for several months.

There are seven species in the Vinca genus. All grow best where the soil is just moist and where they are shaded from mid-day sun.

Vinca Varieties to Grow 

  • Vinca major, Greater periwinkle, is the larger, more aggressive species. Good as an annual, trailing, container, or window-box plant in the North, and it is useful as a perennial groundcover in Zones 7 to 11. Leaves to 3 inches (7.6cm) long, flowers to 2 inches (5.1cm) across. It grows 10-18 inches (25.4-45.72cm) tall. Shear close to the ground occasionally to bring on new growth. The cultivar ‘Variegata’ has green leaves with irregular white margins.  
  • V. minor, Lesser or common periwinkle, with smaller leaves and flowers, has lavender-blue flowers and glossy, green leaves. 8 inches (20.3cm) tall, it grows well in sun in northern climates but does best in shade even there, although it may not bloom as heavily. More restrained, less likely to invade adjacent plantings. Among the many varieties are ‘Alba’, with white flowers; ‘Atropurpurea’, deep purple flowers and small leaves; ‘Aureola’, light blue flowers, yellow veins in leaf centers; ‘Bowles White’ has larger leaves, pinkish buds, and white blooms; ‘Miss Jekyll’, a small grower with white flowers; ‘Multiplex’ has double, bright purple flowers; ‘Ralph Shugert’, white-edged leaves, blue flowers, autumn rebloom; ‘Sterling Silver’ is a blue-flowered form with green leaves speckled with pale green and edged in cream. ‘La Grave’ is similar to (if not the same as) ‘Bowles Variety’. Zones 3 to 9.
