Unlike towering delphiniums, this butterfly delphinium is light and self-supporting, blooming in early to midsummer and drawing hummingbirds and bees. Deer-resistant and reliably hardy, it's a jewel-blue accent for sunny borders in Edina, Woodbury, and Maple Grove.\u003c\/p\u003e\n\u003ch2\u003eBlue Mirror Delphinium 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\u003eBotanical Name\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDelphinium grandiflorum 'Blue Mirror'\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMature Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e12–18 in. tall, 10–14 in. wide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eHardiness Zone\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3–7 (Twin Cities is zone 4b–5a — fully hardy)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eLight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFull sun to part shade\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBloom Time\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eEarly to midsummer, often reblooming if cut back\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFlower Color\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eIntense gentian-blue\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSoil\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMoist, rich, well-drained; amend clay with compost\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 -30°F; often short-lived but may self-sow\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDeer Resistance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRarely browsed — foliage is unpalatable to deer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eLandscape Uses in Minnesota\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eTrue-blue accents:\u003c\/strong\u003e Its rare, pure blue is stunning among warm-toned flowers and silver foliage.
