I am pleased to report that this work is finished. I made a new grouping of plants called "Vegetables" and that grouping includes the 24 custom databases mentioned in the first post of this thread. I then added these options to that group.
You can see an example of it in action here:
Tomato (Solanum lycopersicum 'Kellogg's Breakfast')
Notice the data fields start with "Vegetables" then shows the "Data specific to Tomatoes" and finally it then shows the "Primary Plant Details."
