Annual Thunbergia question

Hello all, I had some left over vines this year and put them all together in a hanging basket-there is African Sunset, Apricot Smoothie, and Raspberry Smoothie. Now will these plants come true from seed or are they going to cross? Thanks for your help- have a beautiful gardening day. Joelle

Joelle, I wish I could answer your qustion. I'd like to know the answer also. In past years, I've had the white and yellow planted together and they didn't mix that I knew of.

This is a start. thank you- I hope some Thunbergia expert comes by...
