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

Last Frost Date

The average date of last frost is May 15 in Zone 3a. It might get as low as -40°F during the coldest months of winter.

Since the USDA zone info for Zone 3a is just an average our actual date of last frost is different every year. Half of the time in Zone 3a there is a last frost after May 15 so make sure that you are prepared to cover your scabiosa if we have a late frost.
