Helleborus Winter Thrillers™ &#x27;Green Gambler&#x27; has apple-green blossoms variously flecked, veined, or edged with maroon, &#x27;Green Gambler&#x27; sets off the color of any of its siblings. Each bloom measures 3in across; double blossoms are an occasional surprise. The plants are vigorous, too, unlike most green-flowered varieties.
