Selected Cuttings from the Washington Park Arboretum (November 28 - December 12, 2011)

1) Cedrus libani ssp. atlantica ‘Glauca’ (Blue Atlas Cedar)

  • This native of the Atlas Mountains of Algeria and Morocco is now placed in the same species as the “Cedar of Lebanon”.
  • Two beautiful specimens are located 38 and 39-6W at the Lynn Street entrance to the Arboretum.

2)  Juniperus virginiana  ‘Blue Coast’     (Red Cedar)

  • Though the species reaches over 100 feet, ‘Blue Coast’ is a shrubby cultivar.
  • Ours are located north of the crab apple trees in 34-6E.
  • Red Cedar (or Eastern Red Cedar if you are from the West) lent its name to the Cedar Waxwing and to Baton Rouge according to Arthur Lee Jacobson.

3)  Chamaecyparis thyoides     (Atlantic White Cedar)

  • Inhabits swamps on the U.S. East Coast.
  • Rarely seen in cultivation.
  • Our best specimens are in 28-3W, west of Azalea Way.

4)  Torreya taxifolia     (Stinking Cedar)

  • Torreya taxifolia is rare even in its very small natural range in southern Georgia and northern Florida where a fungal blight has nearly driven it to extinction.
  • The Arboretum has two specimens:  one at the east end of Loderi Valley (29-3E), the other in the cold frames south of the greenhouse.

5)  ????????????? nootkatensis     (Alaska Yellow Cedar)

  • Variously known as Cupressus (1824), Chamaecyparis (1841), Xanthocyparis (2002) and Callitropsis (2004).
  • Attaining great size and age, Yellow Cedar was one of the most important plants for the Northwest Coast First Peoples. It is still immensely popular as a landscape plant, especially in its weeping forms.
  • Many specimens are located in the Arboretum south of either end of the Wilcox Bridge and in 36-5E, south of the greenhouse.
