Redstem ceanothus occurs from the Siskiyou Mountains of northern
California to southern British Columbia, including Vancouver Island, and extends eastward in montane sites to western Montana [43,44]. It also occurs in northern Michigan [110].

Redstem ceanothus is a prominent component of seral brushfields in
western hemlock (Tsuga heterophylla), grand fir (Abies grandis), western redcedar (Thuja plicata), Douglas-fir (Pseudotsuga menziesii), and mixed conifer communities of the Northwest [26]. In both the Cascade Range and the Rocky Mountains it is found primarily in the ponderosa pine (Pinus ponderosa) zone and in parts of the mixed conifer and western hemlock zones [16].
Idaho and Montana: Common brushfield associates of redstem ceanothus in Douglas-fir forests include Rocky Mountain maple (Acer glabrum), Saskatoon serviceberry (Amelanchier alnifolia), ninebark (Physocarpus malvaceus), oceanspray (Holodiscus discolor), Scouler willow (Salix scouleriana), pachistima (Pachistima myrsinites), common snowberry (Symphoricarpos albus), and snowbrush ceanothus (Ceanothus velutinus) [4,15].
Seral shrubs occurring with redstem ceanothus in western redcedar forests of northern Idaho include common snowberry, trailing blackberry (Rubus ursinus), thimbleberry (R. parviflorus), white spirea (Spiraea betulifolia), creeping snowberry (Symphoricarpos mollis), and bitter cherry (Prunus emarginata) [78].
Common brushfield associates of redstem ceanothus in Idaho (and eastern Washington) grand fir forests include Scouler willow, Rocky Mountain maple, Saskatoon serviceberry, oceanspray, syringa (Philadelphus lewisii), bitter cherry, cascara (Rhamnus purshiana), white spirea, snowbrush ceanothus, and blue elderberry (Sambucus cerulea [26,68,86].
Oregon and Washington: Common shrub associates of redstem ceanothus in western hemlock forests of western Oregon and Washington include vine maple (Acer circinatum), oceanspray, creeping snowberry, and California hazel (Corylus cornuta var. californica) [26].
Tall shrub associates of redstem ceanothus in mixed conifer forests of southwestern Oregon include vine maple, California hazel, Pacific yew (Taxus brevifolia), and giant chinquapin (Chrysolepsis chrysophylla) [26].
Shrub associates of redstem ceanothus in burned ponderosa pine-Douglas-fir forest in northeastern Oregon include ninebark, white spirea, and common snowberry [50].
