I always want to know what the pod parent is, too, so that I can collect pods from different varieties in a flat box and bring them inside together. But, of course, I don't have large quantities of pods from any one plant to deal with (wish I did!). And I've stopped recording anything until I collect pods and then record the cross and number of seeds. I've found that these paper tags work the best for me, and when I used to hybridize roses I used the same type of tags but had to put scotch tape over everything I wrote because they had to stay on for 3-4 months and insects would eat away the paper if I didn't. Rainfall is NEVER a problem here in summer, so they never faded too much. And now since these tags stay on about 60-70 days at most and are in a more protected area I no longer have to use the scotch tape.
