Learning all about plants

Hi all, can you help recommend some resources I can learn to deepen my knowledge of the many kinds of useful plants out there? I would like to learn how to identify and understand different families and types of plants, their uses and needs from soil types to chemistry, etc, with the primary purpose of being able to create permaculture projects in the Northeast/Mid-Atlantic US. I am looking for self-learning resources, books, videos and online courses. I know that the best way to learn these things would be directly from experts in the field, but that's just not realistic for me right now. Thank you!

One of the things that help me was to learn about the plants that grow on my property and what their uses are.  First I had to ID them which is easiest when they flower.  I have several books on plants and herbs which are helpful though I usually use this website:  https://www.wildflower.org/plants-main

It has a search function that I like:  https://www.wildflower.org/plants/
