Shopaholic? Me?

I really want to do up my garden in time for spring. I must start by saying that where as I am a shopaholic, I am certainly not greenfingered. The nearest to green fingers are green gloves!

So let me tell you a bit about my garden. Well it is not a garden per se but a front and back yard and some hardy plants which keep getting attacked by my cats. It would be nice to have some Cherry or Plum trees but lets be realistic.. I do not have the space. So all my plants have to be potted. I have lots of roses (which suprised me how hardy they are). I would love to have some plants to flower constantly even if there were two or three types of plants per pot. But honestly I know nothing about plants…. so I either need to buy a book or call in some help!
