I don't know much aboutngardening but several years ago someone gave me a few mint plants and they spread like crazy. I love having them for mint tea whener I want. This year I plan to try drying some leaves so I will have tea all winter.
I also started some knives last year in a pot. Then I transplanted it to my perennial flower bed. It got beautiful flowers on it and now this year it is coming up again. I will check to see if I can dry some of that as well. Good luck with your plants. After reading all these posts, I think I'd better plant some more herbs.
