One of the best tools that you have as gardeners to help us figure out 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.

The first chance to plant scutellaria in Dallas should be figured out by looking at the USDA zone info.

It's probably a bad idea to plant scutellaria until after the last frost has passed because they require warm weather.

The earliest that you can plant scutellaria in Dallas 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. Any later than that and your scutellaria may not have a chance to really do well. You can get started a little bit earlier by starting your scutellaria indoors.
