I've never tried any Thunbergias, indoors or out, so this probably doesn't have much relevance to my life, but whatever. The blue surprised me.
The ex-job received a new batch of tropical climbing plants about three weeks ago, and T. battiscombei was among them. Mainly I find myself wondering whether it would hybridize with the orange Thunbergias, and if so what color(s) the offspring would be.
In the process of writing this post, which was originally supposed to be just about T. battiscombei, I discovered that I'd never gotten around to posting this picture of T. alata 'Blushing Susie,' or if I had, I didn't tag it in a way that made it possible to find it again. Obviously a grievous error, so I'm correcting that today.
