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

It's a good idea to figure out when you can plant scutellaria by looking at the USDA zone info for Winters.

Planting Calendar for Scutellaria

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

It's probably a bad idea to plant scutellaria until after the last frost has passed because they do not do well in cold weather.

The earliest that you can plant scutellaria in Winters is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant scutellaria and expect a good harvest is probably September. Any later than that and your scutellaria may not have a chance to fully mature. Starting your scutellaria indoors is a great way to get them started a couple of weeks earlier.

Just be sure to remember that USDA zone info for Winters is not always accurate and the actual date of last frost is different every year. Half of the time in Winters you get a frost after February 15 so be sure to be ready to protect your scutellaria in the event of a late frost.
