Local occurrence
Very wide tolerance
for environmental conditions: grows in sun or shade; grows from sea-level to
subalpine; and grows in dry or moist soils.
Plant strategy type/successional stage
Some associates of
Oregon boxwood include Engelmann spruce (Picea
engelmannii), Douglas-fir (Pseudotsuga
menziesii), subalpine fir (Abies
lasiocarpa), white fir (A. concolor),
red fir (A. magnifica), hemlock (Tsuga spp.), western redcedar (Thuja plicata), lodgepole pine (Pinus contorta), Gambel oak (Quercus gambelii), golden chinquapin (Chrysolepis chrysophylla),
Port-Orford-cedar (Chamaecyparis
lawsoniana), quaking aspen (Populus
tremuloides), Rocky Mountain maple (Acer
glabrum), mountain snowberry (Symphoricarpos
oreophilus), bunchberry dogwood (Cornus
canadensis), huckleberry (Vaccinium

malvaceus), lupine (Lupinus
spp.), mountain sweetroot (Osmorhiza
chilensis), queencup beadlily (Clintonia
uniflora), heartleaf arnica (Arnica
cordifolia), columbine (Aquilegia spp.)
groundsel (Senecio spp.), meadowrue (Thalictrum spp.), and pinegrass (Calamagrostis rubescens). (FEIS database)
May be collected as:
Can be
propagated from seeds or vegetatively by cuttings or layering. (FEIS database; Wick, et al. 2001)
Fruiting period is
June through September. Softwood
cuttings can be taken in the spring when juvenile growth is becoming slightly
rigid (the timing will vary depending on elevation and seasonal variation).
(FEIS database)
Seed germination
Seed dormancy can be
broken by a period of after-ripening or by a period of cool, moist
stratification for several months.
(Wick, et al. 2001)
Seed life
Up to 10
years. (Wick, et al. 2001)
Cool, moisture
controlled storage conditions.
Propagation recommendations (plant seeds, vegetative parts, cuttings, etc.)
Seeds can be successfully
germinated and grown in containers for outplanting. Softwood cuttings are also very
successful. Wick, et al. (2001) used
soilless rooting media, 2000-3000 ppm IBA rooting hormone and supplied bottom
heat and top misting during rooting.
Soil or medium requirements (inoculum necessary?)
For cuttings, one study used peat, perlite and vermiculite for rooting after an application of rooting hormone. (Wick, et al. 2001)
In the wild,
Installation form (form, potential for successful outcomes, cost)
Container grown
cuttings or seedlings are most successful for restoration plantings. Transplants can be installed in spring or
fall. (Wick, et al. 2001)
3’ to 5’ centers.
Care requirements after installed (water weekly, water once etc.)
Water regularly at
least during the summer following installation.
On sunny or very dry sites, water regularly for 2 growing seasons
following installation.
