Re: Musa Sikkimensis?
Not sure but the sikkimensis var " Darjeeling Giant" I grew from seed had a lot of redish color and no powdering on the p-stem. It turned progressivel greener as it matured. Not uncommon for some varieties to have a different color pattern as juvinile plants and from what Ive seen loose a lot of it as they mature which might explain less purple on the biggest ( newest? ) leaf.
