One of the best tools that you have as gardeners to help us determine 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 common way of estimating when to plant scutellaria is to consult the USDA zone info for Canyon.

The earliest that you can plant scutellaria in Canyon 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. Starting your scutellaria indoors is a great way to get them started a couple of weeks earlier.
