Nursery contributed plant descriptions

A resident of the Madeira Islands, this winsome evergreen is densely attired in lustrous coppery green 4 to 6 in. long leaves. Copious small white fragrant flowers, resembling Lily-of-the-Valley blooms, embellish large showy rose-tinged panicles that cluster at branch tips from summer to fall and sustain our interest with round long lasting auburn-colored seed heads. Tailor made for narrow sheltered spaces, Clethra arborea's well groomed upright frame requires protection from hard freezes and savors moist, freely draining acidic soil.
