The earliest that you can plant nemesia in Zone 2a is May. However, you really should wait until June if you don't want to take any chances.

The last month that you can plant nemesia and expect a good harvest is probably August. You probably don't want to wait any later than that or else your nemesia may not have a chance to really do well. If you are starting your nemesia indoors then you might be able to get away with starting them a little bit earlier.

Last Frost Date

In Zone 2a the average date of last frost happens on May 15. We can expect an average low temperature of -50°F in the coldest months of winter.

Remember that our actual date of last frost is just an average because it is based on the USDA zone info for Zone 2a and it is different every year. Half of the time in Zone 2a there is a last frost after May 15 so make sure that you are ready to protect your nemesia if we have a late frost.
