Hi everyone,
I have a question for you. I can see on some Internet websites N. ventricosa x aristolochoides classed as a lowland hybrid.
I must confess my scepticism, because everybody knows N. aristolochoides is a real highland specie. The hybridation with N. ventricosa should get a highland hybrid, no ?
What's your opinion ? Do you grow it ? If yes, what are your growing conditions ?
