Heucheras are hotter than ever. We've gathered four here that set each other off with flair, energized by contrasting colors. Heuchera 'Georgia Peach' (PP 19,375) keeps its silvery sheen as it matures from peachy orange to rosy purple. The hybrid x Heucherella 'Alabama Sunrise' (PP 19,611) links to the peach coloring with a central splash of reddish orange on lime green. Heuchera 'Obsidian' (PP 14,836) creates dramatic counterpoints with its glossy, deep maroon leaves that look almost black, while the green-veined, silvery leaved H. 'Rave On' adds tall stems of bright coral-red flowers to the mix of creamy and white midsummer blooms.
Heucheras, which were relatively unknown a few decades ago, have metamorphosed from an obscure genus of North American wildflowers to become one of the great horticultural success stories of the last generation.Heuchera (Coral Bells) and x Heucherella (Foamy Bells, a hybrid between Coral Bells and Foam Flower) have lobed leaves and tiny, bell-shaped flowers on wand-like stems. They make themselves at home in moist but well-drained, organic-enriched soils.
