Dahlias: a Colour Guide by Ted Collins
This title profiles some 1800 varieties of dahlia. Arranged in alphabetical order, and illustrated throughout with over 500 colour photographs, this is a useful guide for both dahlia enthusiasts and exhibitors. Each entry includes a short description of growth habit; type of bloom and colour; advice on the variety's potential for garden, exhibition or cut flower use; the raiser, country of origin and year of introduction (where known); and source of supply of plants or tubers. Practical advice on methods of propagation and successful cultivation is given, along with a brief history of the dahlia, tips on exhibiting and ideas for garden use. The guide also explains the different forms of dahlias and gives a calendar for their care.
