It's a good idea to figure out when to plant scutellaria by reviewing the USDA zone info for Exeter.

Scutellaria are not cold tolerant which tells us that you have to wait until it warms up after all chance of frost has passed before you can plant them.

The earliest that you can plant scutellaria in Exeter 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. You probably don't want to wait any later than that or else your scutellaria may not have a chance to grow to maturity. If you are starting your scutellaria indoors then you might be able to get away with starting them a little bit earlier.
