I have not grown this one. As far as I know, I have never even seen a plant of this species.
Here, however, is a picture of V. leonii in habitat, courtesy of Alain Chautems. It appears we should be growing our vanhoutteas in the crevices of rocky outcrops, surrounded by plenty of weeds. The rocks may allow the plant to get plenty of sunlight while protecting the roots from drying out too much.

Mauro Peixoto's web site has a page about Vanhouttea leonii.
The species V. leonii was described in Alain Chautems's paper "New Gesneriaceae from Minas Gerais" (2002). It grows in Minas Gerais state of Brazil, in the same general area as V. pendula: the mountains near where the three states of Minas Gerais, Espirito Santo, and Rio de Janeiro meet.
