Bismarckia varieties

[abdalav]

Hello everyone,

I'd like to know what are Bismarckia 'green' and Bismarckia 'Mayotte'. Are they botanical varieties of Bismarckia Nobilis, subspecies, non-described species ou just color variations?

I've looked for it in the WCSP/Kew Gardens database and found no info on this.

I think both "Mayotte" and "green" are variations of the same species: Bismarckia Nobilis.

I am not an expert on Bismarckia variations so hopefully someone else may be able to give a better answer.

there is one species, bismarckia nobillis, it has green and silver forms like serenoa repens.  The green form is reputed to be a bit less cold hardy.  The "mayotte" description I heard was silver with shorter petioles than the silver bismarckia.  This from a long term palm talker that had short and long petiole versions in Arizona, full sun.  I don't have any opinion but I have two bizzies almost 10 years in the ground, 6-7' trunk, and one has petioles at least 1-1.5' shorter, and both are in full sun.  The one with shorter petioles is also more waxy(grey/white).  The fruit looks the same to my non botanist eye.   It might just be a genetic allele where one is more sun tolerant than another and the weaker one grows more compactly and with more wax.
