If you’re looking for an easy-to-grow, Summer annual to add some color to your sun garden, you should consider planting annual vinca. Annual vinca, also known as periwinkle or Catharanthus roseus, is a tropical perennial that is grown as an annual in most regions. Many varieties have a trailing or upright habit, and produce beautiful flowers in shades of pink, white, and red.
Vinca is a low-maintenance plant that is perfect for gardeners of all experience levels. When planting, be sure to choose a location with full sun and well-drained soil. Annual vinca will bloom throughout the Summer and into early Fall. To keep plants looking their best, mulch plants and fertilize regularly. Vinca prefers to be hot and dry. Avoid water staying on foliage for extended periods.
If you’re looking for annual vinca that will tolerate disease pressure other vinca can’t, consider ‘Cora’ or ‘Cora Cascades’. These varieties produce large flowers in beautiful colors and have an added disease tolerance.
