Go to the Plant Examples Book page where a free, editable spreadsheet can be downloaded.
It includes all the plants listed in the book. There are two tabs:

Tab two has an alphabetical plant list with categories given for each.
There are a couple of ideas for activities that will build your knowledge of how plants are categorised and used in gardens: see Plant Examples Book page.
