Clematis Duchess of Edinburgh (Clematis 'Duchess of Edinburgh') is a timeless and exquisitely beautiful double-flowered clematis variety celebrated for its large, fully double blooms in pure, pristine white — densely packed with layer upon layer of crisp, overlapping petals that create a lush, peony-like flower of remarkable elegance and sophistication. One of the oldest and most treasured double white clematis in cultivation, Duchess of Edinburgh has been delighting gardeners since its introduction in 1875 and remains a benchmark variety against which all other double white clematis are measured. Producing its spectacular fully double blooms on old wood in late spring to early summer, followed by single or semi-double blooms on new wood in late summer and fall, this classic variety delivers a timeless, ever-changing white display across an extended season. Exceptionally versatile and combining beautifully with virtually any garden color scheme, Duchess of Edinburgh is an outstanding collector's variety and a true garden heirloom. Plants arrive in 2 inch starter pots, well-rooted and ready to establish in your garden.
