For my GCSE project I have decided to design a garden. Can you recommend books on the subject of garden design? Louise from Standish, UK

I am a student at Standish Community High School and for my one of my GCSEs I have chosen to take Graphics and Design. For my GCSE project I have decided to design a garden. If you have any leaflets, brochures or information on the subject of garden design, I would be grateful if you could send me some.
Forum (Hugh):As in all design and drawing, work develops with practice. Give yourself plenty of time to develop – don’t force it. With Garden Design, because there are so many aspects to a garden, your result will probably seem to come as an accident – ideas evolve, and evolve other ideas with gained knowledge. Initially free yourself up – always free up, then control the best ideas. Don’t be afraid to scrap your own work – sometimes ideas come better that way!
Forum (Brian):There is a very good book you may like to use for reference A Handbook for Garden Design by Rosemary Alexander ISBN 0-7063-7204-2 1994. £18.99 In my lecturing I use this as my main work book as it leads the reader through the process of garden design stage by stage. Designing the hard landscaping areas of a garden is relatively easy, the shortfall sadly comes very frequently in the selection of plants to grow and develop in the garden over many years. If you forward your college address details, I may be able to help with a few surplus small publications I have. Feel very free to come back if you need more help. Good luck with your project! You might like to look at car boot sales for copies of the Expert series of books by Dr. D.G Hessayon. These will give you an background range of plants which you can select for planting in your garden.
