It climbs trellises and arbors on a zone 4-hardy vine and, like all clematis, wants its top in the sun and roots in cool shade. Whether you're brightening a shaded entry in Edina, climbing a white-trimmed arbor in Maple Grove, or adding an elegant note to a Woodbury garden — the Duchess brings timeless white to zone 4b–5a yards.\u003c\/p\u003e\n\u003ch2\u003eDuchess of Edinburgh Clematis Plant Details\u003c\/h2\u003e\n\u003ctable class=\"mce-item-table\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eScientific Name\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cem\u003eClematis\u003c\/em\u003e 'Duchess of Edinburgh'\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePlant Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDeciduous flowering climbing vine\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMature Height\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6–10 feet (with support)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMature Spread\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3 feet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSun\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFull sun to part shade (6+ hours for best bloom); keep the roots cool and shaded\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWater\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eModerate — consistent moisture in well-draining soil\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eUSDA Zones\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4–9 (Twin Cities is zone 4b–5a)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSoil\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRich, well-draining; amend Minnesota clay-loam with compost\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePruning Group\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGroup 2 — light prune in early spring; the double flowers form on old wood\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBloom\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFully double white flowers in late spring\/early summer; single white rebloom possible later\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWinter Hardiness\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eReliable to zone 4; mulch the crown the first winter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eDuchess of Edinburgh Clematis Uses in Minnesota Landscapes\u003c\/h2\u003e\n\u003ch3\u003eArbors and trellises\u003c\/h3\u003e\n\u003cp\u003eThe double white blooms glow against dark fences and evergreens.
