Own Root - All of our climbing rose bushes at Heirloom Roses are own root, which means they will produce more blooms, be more hardy, and stay true to variety throughout their lifetimes, contrary to grafted roses. One Gallon - All of our climber rose plants are 12-16 months old and delivered in one gallon containers with rich soil. Hardiness Zones: 5-10 Lightly Fragrant & Continual Blooming - Will bloom continually throughout the growing season. Approximate Size: 11'+ x 8' - This is the indefinite size of the Rambler rose plant when it reaches full maturity. Upon delivery, roses will be around 12-15 inches tall and may be partially defoliated to ensure plant health during shipping. Subject to Amazon's 30 day warranty. Void if granular fertilizer has been used. The introduction of Super Dorothy was a great breakthrough in Climbing and Rambling Roses many years ago as she is a continuous blooming bush pushing out beautiful blossoms from spring through fall. Clusters of beautiful, small, double, powder-puff pink blooms produced in clouds blanket this Rambler making it difficult to see its foliage. Much more hardy than the older Rambler, 'Dorothy Perkins'.
