I have a grown parsley plant that I bought from a store. Where is the core so I can plant more when this dies?
Answers:    Parsley is a biennial meaning it have to go through winter up to that time it will put out flower stalks the following spring.

If you want to save kernel be sure you have at most minuscule 8 plants so you get proper pollination. Without proper pollination the seed will be weak and will not produce the best plants.
The parsley should put out flowers. The seed will come from the flowers. Dry the seeds and set free them in a container.
