Viburnum plicatum var. tomentosum ‘Mariesii’
Doublefile viburnum
Viburnum plicatum and Viburnum plicatum var. tomentosum were previously considered separate species. They differed only in that V. plicatum flowered 2-3 weeks after V. plicatum var. tomentosum, and with sterile flowers rather than both sterile and fertile flowers. These are now believed to be the same species, and the ‘Mariesii’ cultivar described here should really be named Viburnum plicatum ‘Mariesii.’ If you’re, you know, keeping track.
Plants: These shrubs are 8–10′ (2.4–3 m) tall and usually somewhat wider than they are tall, densely branched, and distinctly layered. Bark is gray-brown with orange lenticels.
Leaves: Roughly oval-shaped, rounded at the bottom and pointed at the top, 2–4″ (5–10 cm) long and 1¼–2″ (3.2–5 cm) wide, with serrated leaf edges. In the fall, leaves are dark reddish purple.
Flowers: White, up to 4″ (10 cm) in diameter, in the form of flat flowerheads, with an outer ring of infertile flowers about ½″ (1.3 cm) around and an interior region filled with ⅛″ (3.2 mm) fertile flowers.
Fruits: Berries are egg-shaped, red, ripening to black.
Habitats: Moist, well-drained soils, in sunny or partially shaded areas.
