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

The earliest that you can plant scutellaria in Plymouth 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. You can get started a few weeks earlier by starting your scutellaria indoors.
