As the name suggests, climbing roses feature long, flexible canes that can grow up to 20' long. Unlike ivy, climbing roses are not true vines because they don't have the ability to cling to something else for support. Provide your climbing rose with a trellis or pergola, and it will happily scale its heights. Climbing roses can add a new dimension to the landscape. Creating garden interest on multiple levels generates an excitement of colour and movement. If you choose to forgo a trellis, you can still use them to scramble over a crumbling rock wall or conceal a dilapidated fence!
