Very old seeds
My mother recently found some cockscomb (Celeosia) seeds that my grandmother saved from the last bunch she grew, my mother remembers that they were especially beautiful. She would like to grow them as a memory of her mother.
The thing is, my grandmother never grew those flowers again after my grandfather died--in 1947. The seeds are in a glass jar and have been stored on a basement shelf since at least the mid 70's.
Any hope for these at all? Anything I should do to improve my chances if we do try growing them?
Any help would be appreciated.
