Thanks everyone for sharing your techniques. Very helpful! I have used Dixie cups for collecting hosta seed but for some reason never put them into use for pollen - that will change this year. I too have done similar to Joe with the add new anthers to previous container of drying pollen of same cultivar. I think this year I will just use more Dixie cups and keep it separate and package it in smaller foil packs after dry. My wife & kids hate this time of year as I have pollen scattered around in various little plastic containers that are too easy to bump and spill.
I have lots of test tubes but they tend to be full of plants or contaminated media waiting to be washed out. The plastic test tubes are much cheaper especially if you don't need to autoclave them but I think I will be going with foil as the final storage media.
