i have recently moved into a new property and have a 3 ft high concrete wall of close to 12ft in length in the bottom 3rd on the right hand perimeter of my garden where my next door neighbours had to reinforce the structure of their swimming pool, im looking to put trellis up and cover this wall as its rather unsightly,im looking for ideas and names of a climber that is winter hardy and flowers in summer but doesnt include any berries as i have 2 very young children under 4..id really appreciate any ideas and names of good hardy trellis climbers that will add a bit of colour and are reasonably easy to maintain....hopefully a few of you out there maybe able to help,..many thanks
