The USDA zone info for Audubon should be used to figure out when to plant scutellaria.

Planting Calendar for Scutellaria

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

Scutellaria do not do well in cold weather which means that it is necessary to wait until it warms up after the last frost has passed before you can plant them.

The earliest that you can plant scutellaria in Audubon 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. If you wait any later than that and your scutellaria may not have a chance to grow to maturity. Starting your scutellaria indoors is a great way to get them started a couple of weeks earlier.
