Before planting it is a good idea to find your USDA Zone info to estimate your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Nixa you can determine when it's the best time to plant zinnia by referring to the USDA zone info.

Zinnia do not do well in cold weather which means that it's important to wait until it warms up after the last frost when the weather gets warmer before you can plant them.
