Prom Dress is a large silver coral bells with heavily ruffled pewter leaves traced in dark charcoal veins. The newest leaves carry a violet flush that matches the leaf backs, adding a soft purple tone to the mound.
The foliage lasts well into autumn, so it pairs nicely with mums and pumpkins in fall displays. It grows 8 to 10 inches tall and 16 to 18 inches wide, with small pink flowers in midsummer. Use it for edging, containers, mass plantings or cutting foliage.
What it looks like
A low, full mound 8 to 10 inches tall and 16 to 18 inches wide of heavily ruffled, rounded leaves in pewter silver with dark charcoal veins. New leaves are flushed with violet, and the undersides are violet as well, showing along the frilled edges. Slim stems carry small pink bell flowers in midsummer. At peak the plant is a crinkled silver-gray mound with purple highlights and a light pink haze above.
Growing it with lavender
Its ruffled pewter leaves echo lavender's silvery foliage at a bed edge with some afternoon shade and a little more water.
Care
Takes full sun to full shade; afternoon shade keeps the silver bright in hot sites. Tolerates poor to average soil as long as it drains well; water during dry spells. Hardy in zones 4-9; trim spent flower stems and old leaves in spring.
