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.

You can determine when it's possible to plant scutellaria in Richmond by using the USDA zone info.

Planting Calendar for Scutellaria

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

It's not a good idea to plant scutellaria until after all chance of frost has passed because they are not cold tolerant.

The earliest that you can plant scutellaria in Richmond 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. You probably don't want to wait any later than that or else your scutellaria may not have a chance to fully mature. Starting your scutellaria indoors is a great way to get them started a few weeks earlier.
