When can I plant Strawflowers in Zone 1a

The USDA Zone info is a great tool for gardeners to help us estimate our gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for our area.

By referring to the USDA zone info for Zone 1a you will be able to figure out when to plant strawflowers.


Planting Calendar for Strawflowers

Strawflowers are barely cold tolerant which means that you can get them planted just a bit earlier than plants that are more sensitive to the cold.

The last month that you can plant strawflowers and expect a good harvest is probably July. You probably don't want to wait any later than that or else your strawflowers may not have a chance to grow to maturity. Starting your strawflowers indoors is a great way to get them started a little bit earlier.

Last Frost Date

On average the last frost has passed is on June 15 in Zone 1a. We can expect an average low temperature of -60°F in the coldest months of winter.

Since the USDA zone info for Zone 1a is not always accurate our actual date of last frost changes from year to year. Since half of the time in Zone 1a it frosts late in the year after June 15 be ready to cover your strawflowers if we have a surprise late frost.
