The Australian Cultivar Registration Authority says "Correa 'Dusky Bells' is an extremely compact and very dense shrub, rarely exceeding 0.6m in height. In more sheltered situations plants may grow marginally taller. Plants can spread form 2 to 4m across. Leaves vary considerably in size, from 10 to 40mm long by 5 to 20mm in width. They are elliptic to lanceolate or ovate in shape. The leaf apex is usually obtuse but can be emarginate. They are a dull green above and lighter green below. Both surfaces of the leaves have white stellate hairs when young but these hairs are practically absent on the upper surface of the older leaves. The uppermost part of the stems and branchlets are covered in brown stellate hairs. The tubular flowers are solitary and axillary. The exterior of the corolla is a pale carmine pink. The corolla is from 25 to 40mm in length. The outer surface of the corolla is densely covered in stellate hairs while the inner surface is free of hairs. The flowering period is from March to September though occasional flowers may be found at other times of the year" http://www.anbg.gov.au/acra/descriptions/acc203.html
