How to grow annual vinca
Catharanthus roseus
When to plant annual vinca
Annual vinca is a heat-loving, warm-season annual. UF/IFAS gives planting by calendar month and zone (for example June in zone 7, May to June in zone 8), and notes it may be planted at any time of year in zones 10 and 11. It is set out well after frost once the soil is warm.
Annual Vinca is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
