Dave I thought about how to do the tags so that I both had them linked to the database and yet still showed that the daffs were a long trumpet mix. So I went back and did do two tags as you suggested on the daffodil section of the picture. They over lap. But one tag shows the parent entry for Daffodils in the database so links to the database and the other tag IDs them as a Long Trumpet Daffodil Mix. So I feel I have accomplished what I wanted to in those pictures. Both linking to the information about daffs in general and letting people know the daffs they are looking at are long trumpet types.
I would never have thought of doing two tags so thanks for the suggestion.
