Like other rebloomers it flowers on both old and new wood, so it can still bloom after a Minnesota winter sets the stems back. It's at the cold edge of its range here and does best in a sheltered, part-shade spot. Whether you're brightening a protected foundation in Edina, a courtyard bed in Woodbury, or chasing the classic blue mophead in Maple Grove — Rhythmic Blue brings that coveted color to sheltered zone 4b–5a yards.\u003c\/p\u003e\n\u003ch2\u003eLet's Dance Rhythmic Blue Hydrangea 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\u003eHydrangea macrophylla 'SMNHMSIGMA'\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCommon Names\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBigleaf Hydrangea, Mophead Hydrangea, Let's Dance Rhythmic Blue\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMature Height\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2–3 feet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMature Width\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2–3 feet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eGrowth Rate\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eModerate — compact, rounded habit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSun\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePart shade.
