It blooms in early summer and reblooms in late summer, climbing arbors and trellises on a vigorous zone 4-hardy vine that wants its top in the sun and roots in cool shade. Whether you're brightening an arbor in Edina, climbing a dark fence in Maple Grove, or anchoring a white border in Woodbury — Henryi brings crisp, elegant white to zone 4b–5a yards.\u003c\/p\u003e\n\u003ch2\u003eHenryi 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 'Henryi'\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\u003e8–12 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\u003e3–4 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; blooms on old and new wood\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBloom\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eVery large pure-white flowers with dark anthers; early summer and again late summer\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\u003eHenryi Clematis Uses in Minnesota Landscapes\u003c\/h2\u003e\n\u003ch3\u003eArbors and trellises\u003c\/h3\u003e\n\u003cp\u003eThe big white flowers pop against dark backdrops — a black fence, brick wall, or evergreen hedge in Plymouth.

Cut affected stems to the ground; because you planted the crown deep, it usually resprouts from below.
