Catharanthus roseus ‘Cascade Lilac’

Low maintenance, good drought tolerance, and easy availability all help popularize annual vinca  (not to be confused with Vinca major or Vinca minor, the evergreen ground covers.)  A Madagascar native, annual vinca grows 1 ½ feet tall and wide, blooming continuously in pink, purple, salmon, white, or red from June until frost. Annual vinca is unlikely to be eaten by deer when other plants are available. In spring, plant in any well drained, though not cool, soil. It must have a sunny site for good bloom. For best results, keep soil evenly moist, not soggy.  Use in hanging baskets, borders, as a ground cover or as a houseplant.
