I'm glad to say that Dad has improved dramatically since he first started collecting seeds. Part of his problem was that he refused to use plant markers to begin with, and would forget which kind of plant he was collecting from. His notes were more color based than anything!
Now he takes pictures of the plant, writes the photo number on the envelope, and takes a picture of the envelope, and the seeds inside the envelope. It's a pretty good method! That way, he doesn't have to remember all of the names. He can put the pictures on his computer, and compare them to the ones already on there with all the names attached. And, he doesn't get the seeds mixed up this way, since he has the photo number to go by. These seeds that I'm not exactly sure of were from before he got a little more organized. That is why I don't know as much about the seeds as I should, but I still don't want to waste them!
