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

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

Last Frost Date

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

Remember that our actual date of last frost may not be accurate from year to year because it is based on the USDA zone info for Zone 2a and it is different every year. Since half of the time in Zone 2a it frosts late in the year after May 15 be ready to protect your armeria if we have one of those late frosts.
