It's self-fertile, productive, and disease-resistant, needing only full sun and a sturdy trellis. Whether you're starting a backyard vineyard in Edina, covering an arbor in Maple Grove, or making your own white wine in Woodbury — Frontenac Gris thrives in zone 4b–5a (and colder) gardens.\u003c\/p\u003e\n\u003ch2\u003eFrontenac Gris Grape 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\u003eVitis\u003c\/em\u003e 'Frontenac Gris' (U of MN)\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 fruiting vine (wine grape)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMature Length\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e15–20+ feet on a trellis; train to your system\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 (8+ hours) for ripening and sugar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWater\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eModerate while establishing; fairly drought-tolerant once rooted\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eUSDA Zones\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3–8 (Twin Cities is zone 4b–5a); hardy to about -30°F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSoil\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eWell-draining; tolerates a range of soils.
