Notes

'Sphere Polkadot' vinca (Catharanthus roseus 'Sphere Polkadot') is an annual for borders, containers, pollinator gardens, and accents. It is typically grown as an annual. Frost will kill it, so set it out only after the last frost in spring. This plant likes full or part sun and dry to moist soil of most types. Deer and rabbits usually look elsewhere for a meal. Butterflies and bees visit it, and it is drought tolerant.

Pairs well with Celosia, Pineapple sage, and Penhill Watermelon dahlia.
