Mesh bags, with drawstrings. You can get them in all sorts of colors, from goes-with-everything-in-the-garden-green, though the floral colors of your garden (for color coordination), up to and including black (for those who favor that sort of thing
). (Shown below, protecting the pollen on a next-day daylily bloom.)

Right now I am using them to protect pollen on certain daylily seedlings. I
could put them on the iris pods (I have plenty of them), but the reality is that I'm going to grab those seeds at the first hint of the pod cracking. (They are great for protecting daylily seeds from loss, though. Daylily pods crack open and spill seeds almost before you know it, and we generally seem to be traveling when some of the pods ripen. This has been the only thing which has worked for me, and the bags do double duty - pollen protecting at one end of the season, pod/seed protecting at the other.)
