How nice of the perennial industry to finally have such a gem as a reference guide. The propagation table alone is worth the price, combining for the first time most available information in one place. It is very complete, and would be a great asset to any university teaching perennial production. Complete information on such subjects was only available in piecemeal form and would have to be laboriously compiled to create a student guide or nursery reference tool. With this book countless hours of searching can be eliminated.
