Hello Jim I have flowering specimens, growing side by side & I also find citrina is consistently more robust, flavisima leaves are not only thinner but also droop a little, citrina is more upright, flower petals are consistently slightly longer & visibly thinner & can often be a little twisted. citrina has a well formed petal I'n comparison.. I think the flavissima has far greater florescence especially under a camera lens If my computer wasn't broken I could show u what I mean :( Steven : ) On 25/02/2014, at 7:09 AM, James SHIELDS <jshields46074@gmail.com> wrote: > After looking at the PBS wiki and other places, I wonder how to tell the > difference between Zephyranthes citrina and Z. flavissima? > > Any help will be greatly appreciated. > > Jim > > -- > James Shields jshields46074@gmail.com > P.O.
