Callicarpa dichotoma ‘Duet’. Registered 23 October 2007. Registrant: Sandra M. Reed, U.S. National Arboretum, USDA-ARS, 472 Cadillac Lane, McMinneville, TN 37110, U.S.A. Callicarpa dichotoma ‘Duet’ originated as a sport of Callicarpa dichotoma ‘Albifructus’ and was found at the Tennessee Technological University (Cookeville, TN) by Gary Bachman and Edgar Davis. This new cultivar differs from C. dichotoma cultivars by having variegated (green and light gold) foliage and white berries. Occasional reverent shoots are observed, but the variegation pattern is very stable. This cultivar has been tested by the U.S. National Arboretum (McMinnville, TN) and jointly released by the U.S. National Arboretum and the Tennessee Technological University in November 2006. It has been assigned the Plant introduction number PI651521. A specimen has been deposited at the U.S. National Arboretum Herbarium (NA).
Fagus grandifolia ‘Ferncliff’. Registered 16 June 2006. Registrant: Brian P, Riley, ODNR-Division of Forestry, 2045 Morse Rd., Bldg. H-1, Columbus, OH 43229. Fagus grandifolia ‘Ferncliff’ originated as a chance wild seedling in what is currently the east side of section H of Ferncliff Cemetery and Arboretum, 501 W. McCreight Ave., Springfield, OH. The new cultivar was first observed by Brian P. Riley in March 2001 as a mature tree, aged approximately 125 years. It is distinguished by having bark that is shallowly fissured into conspicuous diamond shapes even down to twigs 1-1.5 cm thick, and which resembles that of an Amelanchier sp. The new cultivar also has particularly dark green, glossy foliage. The original tree occurs in an open environment and has developed a compact dome-shaped crown of elegant, arching branches. If an infraspecific taxonomy within Fagus grandifolia is recognized, ‘Ferncliff’ would be placed in Fagus grandifolia Ehrh. var. grandifolia. Fagus grandifolia ‘Ferncliff’ is propagated via grafting onto Fagus grandifolia understock (attempts using F. sylvatica as understock have not been successful), and is being commercially introduced by a select few nurseries in Ohio, as well as Heritage Seedlings Inc. in Salem, Oregon. The trademark name Diamondbark American Beech has been accepted and was approved on July 24, 2007, by the United States Patent and Trademark Office (Registration No. 3,270,662). Diamondbark American Beech™ is a registered trademark of Ferncliff Cemetery & Arboretum, Springfield, Ohio. A cultivar standard, including photographs, of Fagus grandifolia ‘Ferncliff’ has been deposited at the Brooklyn Botanic Garden Herbarium (BKL).
