SK 3443 30 April 2022: 6 very high res. images.
Habit : Cultivated
I think looks different from images at Ruellia elegans
This is an neotropical bird-pollinated Ruellia but I can’t identify which from the photo. You could contact Erin A. Manzitto-Tripp, who might be able to name it.
From where? Prob R brevifolia
It is from Eden Project, Cornwall, UK
I guess Ruellia brevifolia (Pohl) C.Ezcurra is a perfect match.
