I take a similar approach in this children's book: https://github.com/ralienpp/book-two. In the end there is a section about the trees* that grow in the area, their leaves and fruits - so kids can learn to identify them. I'll incorporate some of these materials in the next iterations of the book.

The first link in the repo readme is for the on-screen PDF, you can look at the pictures.

* One of the characters in the story uses trees to figure out where they are and find their way back home.

Maybe not. Would be confusing for the children.

After taking a quick look, many of this fruit varieties don't exist anymore. Other were renamed and other paintings reflect fruit diseases, not the fruit itself. Botanical art is valuable art, but this work does not reflect the present.
