Are you looking for shrubs, perennials or annuals? How big is the front garden? Does it have a hedge, a fence or a wall, and how high (roughly) are they?

Also, what type of soil do you have - clay, chalk, acid, alkaline, etc - as this will have a big impact on what will and won't grow.

And where are you in the UK - we don't need your address, but the area is important from a temperature point of view.
