dlgoff said:I was talking to the neighbor the other day about saving seeds. I don't remember her saying what type of plant, but her father-in-law planted 35 year old seeds he had sealed in a mason jar that germinated. Some of the seeds I've saved don't seem to do well. Like my 1980s honeydew melon seeds.
I am impressed with germination of his 35 year old seed.
I've noticed each kind of seed differs in viability. In my experience, smaller seeds seem to fair better than larger ones, in viability > 2 years after saving them. For seeds older than one year old, I typically test them on moist paper towels sealed in plastic zip bags. If you keep track of how many seeds you put in the towels, label and date the bags, you can generate an accurate record of % germination and days to germination by cultivar.
Generally speaking, to maximize the storage of viable seeds. it is a good to keep seeds in tightly sealed containers, in a cool, dry place.
The oldest seed I am aware of germinating and growing into a healthy plant, is the
32,000 year old arctic flower; a narrow leaved campion.
