This is a much larger plant than its HMF description suggests, in my garden at least, where I prune hard each year to keep it at about two metres high by six metres wide. It is the only one of my roses that I prune with the hedge shears. It does look ugly for a few weeks, but always bounces back with prolific new growth and copious blooming.
