One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

A way of estimating when it's a good idea to plant scutellaria is to refer to the USDA zone info for Zone 7b.

Planting Calendar for Scutellaria

Frost tolerance for scutellaria:	Not tolerant of frost.
When to plant:	After the last frost has passed.

You can not plant scutellaria until after the last frost because they do not do well in cold weather.

The earliest that you can plant scutellaria in Zone 7b 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 scutellaria and expect a good harvest is probably August. Any later than that and your scutellaria may not have a chance to fully mature. You can get started a few weeks earlier by starting your scutellaria indoors.

Last Frost Date

The average date of last frost is April 15 in Zone 7b. You can expect an average low temperature of 5°F in the coldest months of winter.

Keep in mind that USDA zone info for Zone 7b may not be accurate from year to year and the actual date of last frost changes from year to year. Half of the time in Zone 7b last frost occurs after April 15 so always be ready to protect your scutellaria in the event of one of those late frosts.
