Do seeds ever die?
A packet of vegetable seeds may look dry, brittle, and lifeless, but in many cases, seeds are very much alive.
Inside each plant seed is the embryo of a future plant.
However, seeds do not remain alive forever.
How long seeds remain viable depends on the type of seed and how well it is stored..
What is the longest lasting seed?
The oldest mature seed that has grown into a viable plant was a Judean date palm seed about 2,000 years old, recovered from excavations at Herod the Great’s palace on Masada in Israel. It had been preserved in a cool, dry place, not by freezing. It was germinated in 2005.
Can old seeds germinate?

Why do good seeds sink?
Seeds may float because they lack viable embryos or nutrient stores, making them less dense than “good” seeds that sink in water. Or, they may float because they have air pockets inside, which don’t always affect seed vigor or viability. The only sure way to test germination is to use the coffee filter method.
What do I do if my seeds don’t sprout?

How do you know if a seed is viable?
If you have large seeds like peas, beans and corn left over from last year, an easy way to test for their viability is to fill a shallow pan with water and pour the seeds in. If they sink, they’re fine. If they float, toss them.
How do you tell if a seed is male or female?
If what you’ve got is a handful of seeds, it’s pretty much impossible to tell which ones are male or female. The only way true way to tell the plant’s gender is to plant some seeds, then wait. After a period of several weeks, it will begin to pre-flower, or form a small bud in the crux of a branch.
