Plants and seeds (Plymouth)

Hello, I’m kind of new to the gardening world and so is my sister. She doesn’t know about trash nothing so I told her I would venture out and try to find anyone that’s willing to share seeds and plants with me and her I had a friend that gave us some, and now I am looking to see if anybody has anymore, but they would be willing to share with us fruits, vegetables, flowers, and also any information that they would be willing to provide thank you in advance fast pick up promised
