Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of making a decision about when it's a good idea to plant coreopsis is to examine the USDA zone info for Norfolk.

Planting Calendar for Coreopsis

Frost tolerance for coreopsis:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Coreopsis do well in moderate cold which means that you can start planting them earlier than other frost tender plants.

The earliest that you can plant coreopsis in Norfolk is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant coreopsis and expect a good harvest is probably September. You probably don't want to wait any later than that or else your coreopsis may not have a chance to fully mature. Starting your coreopsis indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

The average date of last frost is April 15 in Norfolk. It might get as low as -20°F during the coldest months of winter.

It's important to remember that USDA zone info for Norfolk may not be accurate from year to year and the actual date of last frost is different every year. Half of the time in Norfolk there is a last frost after April 15 so always be ready to cover your coreopsis if you have a late frost.
