Rose

A rampant, vigorous rose, it makes an impressive tangled mass of growth when allowed to romp up a tree, although its bendy stems can also be trained around a pillar or over a pergola. It flowers once, in summer, when it's covered in a mass of small, white, scented flowers which are followed by red hips. When being grown up a tree, it's impossible and unnecessary to prune, but on ornamental structures the side-shoots should be trimmed back after flowering to a new shoot for the first two years. Thereafter, cut out one-third of the oldest stems each year at ground level to encourage new vigorous stems to shoot up. It has been given the Award of Garden Merit (AGM) by the Royal Horticultural Society.
