October Color Appears at the Washington Park Arboretum

October 16th, 2012 by Pat Chinn-Sloan

Selected cuttings from the Washington Park Arboretum (10/8/12 - 10/21/12)

1)   Cotoneaster conspicuus

  • This showy member of the rose family is native to Tibet.
  • Like most other specimens of the genus Cotoneaster, C. conspicuus has an equally stunning, early summer display of white flowers.
  • C. conspicuus can be viewed along the north border of the Graham Visitor Center parking lot.

2)   Ilex verticillata ‘Winter Red’      Black Alder, Winterberry

  • Native to eastern North America, winterberry is an important winter food source for wildlife including raccoon, red squirrel, wood duck and ruffed grouse.
  • The cultivar ‘Winter Red’ produces intensely red berries that can last until spring.
  • I.v. ‘Winter Red’ can be seen just to the north of the Overlook Pond on Azalea Way.

3)   Pyracantha rogersiana ‘Flava’     Firethorn

  • Many firethorns are grown for their showy berries in fall, which can range from lemon-yellow to scarlet.
  • Pyracantha has traditionally been used as a decorative ornamental, as a pollen source for bees and for home security due to their vicious thorns.
  • Several firethorn species and cultivars can be seen along Arboretum Drive just south of the Graham Visitor Center.

4)   Sorbus cashmiriana       Kashmir Rowan

  • Native to the western Himalayas, this rowan bears corymbs of white flowers in late spring followed by pink-tinged white pommes.
  • Our Sorbus Collection is located on the east side of Arboretum Drive between Crabapple Meadow and our giant sequoia grove.

5)   Viburnum sp.

  • This Viburnum, which was collected in China, has yet to be identified to a species.
  • The tiny, brilliant red berries are unusual to the genus.
  • This Viburnum is located along Azalea Way near our Fraxinus (True Ash) Collection.
