This superb shrub rose has proven to be extremely hardy!
 
William is a dependable garden rose that produces a massive wave of roses early summer with an equally good showing later in the season. It is rarely without a few flowers in between these big flushes. It's health is well above average as is its winter hardiness. The plants are well mannered and will fit into any type of garden from English cottage to something more formal.
 
This rose is grafted on on multiflora.
