In defense of seed fluff... if I'm sending seed packets of Asclepias or Cynanchum in a padded envelope instead of a box I'll leave the fluff in tact because it makes great packing material that protects the seeds from being crushed. With that said, when I donate to PBS BX I pack things as safely & optimally as possible for Dell, using boxes, vermiculite, bags, etc. And I usually contact him ahead of time if I have any questions or concerns. Hooray for seed fluff! #naturespackingmaterial #ImAFluffer Tongue-in-cheek, Dennis in Cincinnati
