I am trying to figure out how to differentiate the Strelitzia alba from the Strelitzia nicolai plant. I know the nicolai plant grows 30 ft whereas the alba reaches 15 ft, but is there any other criteria to differentiate the two? I notice some giant birds have a darker leaf color, but I can not find leaf color as a criterion.
Also, does the Âvariegated white stretlitziaÂ a seed mutant of the alba nor nicolai?
Thanks for any input.
