Registered in 2002 by Hans Hansen and Walters Gardens, this variety is a tetraploid sport of the classic 'Sea Thunder', which grants it a significantly thicker leaf substance and much greater garden vigour. It features upright, heart-shaped leaves with a brilliant, snow-white centre that is dramatically framed by an extra-wide, dark green margin. This \"flaming\" variegation pattern creates a luminous focal point that holds its integrity beautifully from its spring emergence right through the humid peak of a Canadian July.\u003c\/p\u003e\n\u003ch3\u003eWhy It Stands Out\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrisp Tetraploid Contrast:\u003c\/strong\u003e The pure white centre stays bright and stable, providing a sharp \"halo\" effect against the saturated green borders.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImproved Leaf Substance:\u003c\/strong\u003e Being a tetraploid, it boasts thick, leathery foliage that offers elite resistance to slug damage compared to its parentage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUpright Architectural Habit:\u003c\/strong\u003e Forms a dense, vase-shaped mound that adds vertical interest and allows for smaller companion plants to be tucked around its base.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLuminous Shaded Glow:\u003c\/strong\u003e The wide white centres act as a natural reflector, illuminating the darkest corners of your woodland landscape.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLavender Summer Spikes:\u003c\/strong\u003e Produces elegant lavender flowers on sturdy, upright scapes in mid-to-late summer, attracting local pollinators.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specs\u003c\/h3\u003e\n\u003ctable style=\"width: 100.074%; height: 97.969px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003cth style=\"width: 24.3341%; height: 19.5938px;\"\u003eFeature\u003c\/th\u003e\n\u003cth style=\"width: 72.4735%; height: 19.5938px;\"\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 24.3341%; height: 19.5938px;\"\u003e\u003cstrong\u003eSize\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 72.4735%; height: 19.5938px;\"\u003e60 cm Height \/ 105 cm Width\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 24.3341%; height: 19.5938px;\"\u003e\u003cstrong\u003eHardiness Zone\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 72.4735%; height: 19.5938px;\"\u003eCanadian Zones 3–9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 24.3341%; height: 19.5938px;\"\u003e\u003cstrong\u003eColour\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 72.4735%; height: 19.5938px;\"\u003ePure White centre with Wide Dark Green margins\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 24.3341%; height: 19.5938px;\"\u003e\u003cstrong\u003eLight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 72.4735%; height: 19.5938px;\"\u003ePartial Shade to Full Shade\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eGrower's Tip\u003c\/h3\u003e\n\u003cp\u003eTo keep the white centre of 'American Sweetheart' pristine, site it in a location with filtered light or deep shade; while its tetraploid nature makes it tougher than most white-centred hostas, protection from the parching afternoon sun prevents leaf stress.
