One of the great horticultural success stories of the last generation, Heucheras have metamorphosed from an obscure genus of North American wildflowers to garden stars available in a seemingly endless array of cultivars. 'Obsidian' is a perfect illustration of why these perennials are finding such popularity. The glossy dark maroon, almost black, leaves keep their color all season, posing a startling contrast to the carillons of white flowers borne in June and July. 'Obsidian's' 16-inch-wide mound of polished leaves makes a strong statement as a solo planting, and when massed, a setting of black-tie elegance for the display of other floral treasures. PP 14,836
Please note: So plants may properly establish before winter, we recommend early fall planting of Heuchera in colder zones (Zone 5 and lower).
Exceptionally cold hardy, Heucheras make themselves at home in sun or partial shade on moist but well-drained, organic-enriched soils. A traditional favorite of cottage gardeners, they can in their new, more carefully bred incarnations, hold their own as well in a formal mixed border, or in a clearing of the woodland garden.
