I have flower seeds (zinnia's and morning glory) from 2017 - some from 2016. Do seeds expire?
flower seeds from 2017 okay to plant?
Seeds do expire zinnias are said to last 5-6 years
There are seed viability charts online
Clear creek seeds has a good one but you will find many via google search
You can always do a germination test in a paper towel
This is very helpful and thank you very much for the resource (Clear Creek).
I'll try the germination test on the morning glory's. Should be fun!
