I am Ontario Canada here and have both going to bloom this year
Nepalense is very fussy on how it grows and does not like the wet falls at all......
I am planting mine once they bloom under an overhang on my house that seldom gets much rain but enough snow and see how it goes
Kushi Maya they say is far easier to grow.........
one is a species and one is cross.............
I opted to try both of them here but Kushi Maya looks very sturdy and is putting out great leaves on the plant and so on
Nepalense is far off from blooming yet and it travels quite a way in the pot or ground before it even blooms.........it is species.....
