The USDA Zone info is a great tool for gardeners to help us figure out your gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Edinburgh you can determine when it's possible to plant scutellaria by using the USDA zone info.

Planting Calendar for Scutellaria

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

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

The earliest that you can plant scutellaria in Edinburgh 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 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.

Last Frost Date

In Edinburgh the average date of last frost happens on April 15. In the coldest months of winter you should expect an average low temperature of -10°F.

Since the USDA zone info for Edinburgh is not always accurate the actual date of last frost changes from year to year. Since half of the time in Edinburgh there is a last frost after April 15 be ready to protect your scutellaria in the event of a surprise late frost.
