When should I plant cosmos in my city?

The best time to plant cosmos depends on your local climate zone. It thrives in temperatures between 15°C and 28°C. Wait until after the last frost in your area. Check your city's planting calendar on GrowByCity for exact dates.

Can I grow cosmos in winter?

Cosmos is not frost tolerant and cannot survive winter outdoors in most temperate climates. In tropical areas (USDA Zones 10+), it may grow year-round.
