Gladiolus seed viability and the Saunders' book

I think it probably does depend on species. But I also think the seeds also
do have relatively limited viability compared to something like Calochortus
or Lilium. I had much lower germination rates with Silverhill Gladiolus
seed (multiple species) that I stored for a year (refrigerated, dry, in
plastic bags) than I did with seed I sowed shortly after receiving it.
