One of the first steps you take when you are estimating your gardening schedule is find your USDA Zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of estimating when you can plant strawflowers is to consult the USDA zone info for Zone 10b.

Planting Calendar for Strawflowers

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

Strawflowers do ok in moderate cold which tells us that you can get them planted just a bit earlier than more sensitive plants.

The earliest that you can plant strawflowers in Zone 10b is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant strawflowers and expect a good harvest is probably September. If you wait any later than that and your strawflowers may not have a chance to really do well. If you are starting your strawflowers indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date

The average date of last frost is January 31 in Zone 10b. In the coldest months of winter you should expect an average low temperature of 35°F.

Just be sure to remember that USDA zone info for Zone 10b is not always accurate and the actual date of last frost can change quite a bit from year to year. Half of the time in Zone 10b there is a last frost after January 31 so be sure to be ready to cover your strawflowers in the event of one of those late frosts.
