Propagating Orchis mascula from tubers?

[orchid360]

I've thought it would be cool to grow a bunch of Orchis mascula and eventually make some tubers into salep.
But I don't want to undertake starting from seeds.

I’ve read Orchis mascula has two tubers, is it possible to divide them and get two plants, or does the plant need both?

Thanks for any light you can shed on the subject.
