The Best Climbing and Pillar Roses
For you who love the abandon and vigor of the climbing Rose here is an assortment of Climbers for all climates that is reliable, covers all shades of color, and constitutes, we think, one of the most complete offerings of its kind in America.  Strong 2 and 3 year old, field grown plants that will quickly give a wealth of bloom. We also carry a stock of larger Climbing Roses, with trellises, in tubs for immediate effects.
