When can I plant Strawflowers in Zone 2a

One of the first steps we take when we are making a decision about our gardening schedule is find our USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for our area.

You can figure out when it's a good idea to plant strawflowers in Zone 2a by looking at the USDA zone info.


Planting Calendar for Strawflowers

Frost tolerance for strawflowers: Tolerant of a very small amount of frost.
When you should plant them: Up to 3 weeks before last frost.

Since strawflowers are one of those plants that can tolerate a tiny bit of cold weather you can plant them a bit earlier in the year than other plants that might not handle the cold.

The earliest that you can plant strawflowers 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 strawflowers and expect a good harvest is probably August. Any later than that and your strawflowers may not have a chance to grow to maturity. You can get started a couple of weeks earlier by starting your strawflowers indoors.

Last Frost Date

On average all chance of frost has passed is on May 15 in Zone 2a. We can expect an average low temperature of -50°F in the coldest months of winter.

Keep in mind that our actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 2a and it can change quite a bit from year to year. Half of the time in Zone 2a we get a frost after May 15 so always be ready to cover your strawflowers if we have a surprise late frost.
