Selected cuttings from the Washington Park Arboretum (December 12 - 26, 2011)

1)  Cornus sanguinea ‘Midwinter Fire’
(Midwinter Fire Dogwood)

  • Perhaps the first dogwood to show its bright winter stems, Midwinter Fire will continue to be the show-stopper of the twig bed until dressed in leaves again.
  • You will have no trouble finding this shrub in the Witt Winter Garden.

2)  Euonymus myrianthus   (Spindle Tree)

  • This bushy, evergreen shrub has bright orange-yellow fruit which split open to reveal the showy red arils of the seeds.
  • This spindle tree is native to China and is growing among our Asiatic Maples.

3)  Salix irrorata   (Bluestem, Sandbar Willow)

  • This upright shrub from the southwest U.S. has purple to lavender shoots, which have a white bloom in the winter.
  • This willow is coppiced each year to maximize its showy shoots.

4)  Thujopsis dolobrata   (Hiba Cedar)

  • This beautiful cedar is native to Japan.
  • The foliage is similar to our native Thuja, but larger and more lustrous with distinctive white
    markings on the undersides.
  • We have a young specimen in the Woodland Garden and a T.d. var. hondai at the very south end of Azalea Way.

5)  Vaccinium uliginosum ssp. occidentale   (Western Bog Blueberry)

  • The western bog blueberry grows in wet conditions in alpine or cold weather regions including tundra, where it is a major food source for wildlife such as grouse, caribou and bears.
  • The leaves of bog blueberry can accumulate heavy metals without harm to the plant, making it valuable in mine prospecting and reclamation.
  • A fine specimen is located at the south end of our Asiatic Maple collection.
