Tender Perennial flowering plant grows up to 20-40 cm high. Beautiful flowers in a great variety of pink and white colours, up to 3 cm in diameter. Use for arrangements and flower beds.  Where winters are harsh, it’s common to grow vinca as an annual. Vinca blooms in spring to early summer and can bloom in fall if cut back in the summer. In late summer, before temperatures drop, cut back vinca vines to half their length or less to increase fall flowering. To increase the odds of vinca survival where freezing is common, overwinter vinca in a protected place. Pot the plants in the fall before the ground hardens and move them to a greenhouse or indoors near a south-facing window.
