Questions About An Obscure Plant

[Subrosa]

Hi! I'm looking for anyone who can help with some first hand experience growing Melegueta Pepper, Aframomum
melegueta. Although the seeds are growing in popularity here as a spice, the plants themselves are apparently extremely rare in cultivation. At least that seems to be the case here in the US. I suspect that only those who have worked in a botanical garden or a similar situation would have ever seen an actual plant here. However due to the international nature of this forum, perhaps a fellow hobbyist could provide some info. I'm interested in any experience, especially germination advice. Thank in advance!
