Oceanspray occurs from the western Cascade Mountains to the Pacific coast, from British Columbia south to California, east to northeastern Oregon, northern Idaho and eastern and western Montana [43,52].

Oceanspray is dominant or subdominant in a variety of habitat and community types throughout the Pacific Northwest. Habitats vary widely, from climax forests with moist, deep soils to droughty timbered or talus slopes [47,33,43,52]. Oceanspray dominates the shrub layer in Douglas-fir/oceanspray associations in Oregon's Willamette National Forest. These are old-growth stands that are structurally diverse with a mix of long-lived canopy species and an intermediate canopy of smaller, younger trees. Most of the stands are under 150 years old, reflecting a relatively high fire periodicity under natural conditions [48].
Species commonly associated with oceanspray include hollyleaved barberry (Mahonia aquifolium) in British Columbia [72], Cascade azalea (Rhododendron albiflorum) [3,85], western hemlock (Tsuga heterophylla) [70], Douglas-fir (Pseudotsuga menziesii) [44,59,70,92], white spirea (Spiraea betulifolia ) [3], and vine maple (Acer circinatum) [3,95,6] in western Washington and Oregon, curlleaf mountain mahogany (Cercocarpus ledifolius) [37] in eastern Oregon and Washington, Rocky Mountain maple (Acer glabrum) [63,62,50,84], serviceberry (Amelanchier spp.) [64,63], redstem ceanothus (Ceanothus sanguineus) [71], and mallow ninebark (Physocarpus malvaceus) [71,64,63,86] in northern Idaho, and tanoak (Lithocarpus densiflora), and evergreen huckleberry (Vaccinium ovatum) [56] in northern California.
