Evening Gown makes a big impression with oversized, glossy black leaves up to 6 inches across, each edged in deep ruffles. The texture is bold enough to anchor a container on its own or break up fine-leaved plants in a border.
The mound grows 12 to 14 inches tall and up to 2 feet wide. In midsummer, sturdy stems hold pink buds that open to white flowers. Color and vigor are best in part shade, and it has performed well in university trials, including in Michigan.
What it looks like
A substantial rounded mound 12 to 14 inches tall and 20 to 24 inches wide of very large, glossy, near-black leaves up to 6 inches across, each with deeply ruffled, wavy margins that catch highlights. Stout flower stems rise 18 to 20 inches in midsummer with narrow clusters of pink buds opening to small white bells. At peak the plant looks like a mound of polished black ruffles topped by pale pink-white wands.
Growing it with lavender
Its large black ruffled leaves suit a part-shade bed rather than the lavender row; pair it there with ferns, chartreuse hostas or silver foliage.
Care
Grows in full sun to full shade but colors and performs best in part shade. Tolerates poor to average soil as long as it drains well; keep watered during dry spells. Hardy in zones 4-9; remove spent flower stems and winter-damaged leaves in spring.
