Useful wild plants: Honeysuckle
Honeysuckle, like kudzu was introduced into the US as an erosion fighting plant. Of course, being a non-native species, it took hold, and grew everywhere. Now like its cousin, it's considered a pest species for eradication.
Great! Let's try. For new foragers, we want to learn plants that are easily identifiable, and the distinct smell of honeysuckle and it's abundant flowers means that every child age 6 or older has probably been able to find this plant and suck the nectar from them. The flowers can also be eaten too.
But that's not all. The plant is so useful for Asian medicine, that to list the uses would require about ten posts. Please independently read about it, for like the black walnut, this is an essential medicinal. It is mild and treats infections very well, and tolerated by the very young and elderly.

But wait, there's more! The honeysuckle's abundant vines make excellent and easy to make baskets. No more searching for loads of material, as it makes so much that you need not worry about pruning it too deeply.

And yet, there's more. Honeysuckle easily ignites, so it's very useful as a firestarter.

When learning to forage, we want to learn the easiest plants to identify that produce the most harvest and that can easily be found and can are multipurposed. I have deliberately done just that, in order to save the most people in a collapse. If you only learned the ones to date, then you could most likely make it.
