Mahogany Monster lives up to its name with glossy mahogany red leaves that can reach 6 inches across. The clump fills out quickly into a hefty mound 12 to 16 inches tall and more than 2 feet wide, giving real presence in a border or a large container.
The color stays steady all season, with older leaves taking on a coppery cast. In midsummer, thick burgundy stems rise as tall as 3 feet, carrying masses of light pink buds that open to cream flowers, keeping the flower display in scale with the big foliage.
What it looks like
A large, low, mounding clump 12 to 16 inches tall and 22 to 28 inches wide of glossy, rounded mahogany red leaves up to 6 inches across with lightly ruffled edges. Older leaves shift toward coppery red. In midsummer, thick burgundy stems 32 to 38 inches tall hold dense clusters of light pink buds opening to tiny cream bells. At peak the plant is a broad, shiny red-brown mound with tall pink-cream plumes above it.
Growing it with lavender
Its large mahogany leaves give weight to the shaded end of a lavender bed, provided it gets more summer water than the lavender.
Care
Grows in full sun to full shade; afternoon shade keeps the leaves glossy in hot sites. Plant in average to fertile, well-drained soil with regular watering; hardy in zones 4-9. Cut back flower stems after bloom and tidy old foliage in early spring.
