Plant Data Sheet
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 spp.), mallow ninebark (Physocarpos 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 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)
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.
