Clematis Multi Blue (Clematis 'Multi Blue') is a spectacular and highly sought-after double-flowered clematis variety celebrated for its extraordinarily full, densely packed blooms in rich, deep blue-purple — large, multi-layered flowers with an outer ring of broad, overlapping petals in deep violet-blue surrounding a dramatic, spiky central pompom of narrow, pointed petals and petal-like stamens in matching deep blue that create a breathtaking, complex floral display of exceptional depth and richness. A sport of the classic Clematis 'The President,' Multi Blue inherits all of its parent's vigor and reliability while delivering a dramatically more complex and visually extraordinary flower. Producing its stunning fully double blooms on old wood in late spring to early summer, followed by semi-double to single blooms on new wood in late summer and fall, Multi Blue delivers a unique and ever-changing deep blue display across an extended season. Compact, free-flowering, and exceptionally garden-worthy, this outstanding collector's variety is equally at home on a trellis, obelisk, or in a large patio container. Plants arrive in 2 inch starter pots, well-rooted and ready to establish in your garden.
