The USDA Zone info is a great tool for gardeners to help us determine your gardening schedule. 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 it's the best time to plant scutellaria is to use the USDA zone info for Peoria.

Planting Calendar for Scutellaria

Frost tolerance for scutellaria:	Not tolerant of frost.
When to plant:	After all chance of frost has passed.

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

The earliest that you can plant scutellaria in Peoria 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. Any later than that and 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.
