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

In Woodland you can figure out when it's the best time to plant thunbergia by referring to the USDA zone info.

Thunbergia are not cold tolerant which tells us that it is necessary to wait until it warms up after the last frost has passed before you can plant them.

The last month that you can plant thunbergia and expect a good harvest is probably August. You probably don't want to wait any later than that or else your thunbergia may not have a chance to grow to maturity. Starting your thunbergia indoors is a great way to get them started a little bit earlier.
