Other Idaho shrubs are frequently unique to a particular vegetation type. Examples of these are discussed below.
In arid areas dominated by sage brush, one commonly finds the following shrubs: gray rabbit-brush, green rabbit-brush, mountain snowberry, antelope bitterbrush, spineless horse-brush, matchbrush, curl-leaf mountain-mahogany, shrubby cinquefoil, lemonade sumac, hood’s phlox, prickly phlox, and creeping oregongrape. In arid, more alkaline areas sage brush is often replaced by or is growing in combination with black greasewood, spiny hopsage, catclaw horse-brush, and shadscale. In the ecotone between sage brush dominated areas and coniferous forests, blue elderberry and sticky laurel are common and in some locations bearberry honeysuckle also occurs. Within woodlands one often finds scouler willow, mountain lover, western chokecherry, serviceberry, thimbleberry, nootka rose, bearberry, cascade mountain-ash, shiny-leaf spiraea, creambush ocean-spray, gland ocean-spray, rocky mountain maple, bigtooth maple, huckleberries, honeysuckles, and various currents and gooseberries. In riparian areas one finds red osier dogwood, woods rose, various species of willow, black cottonwood, narrowleaf cottonwood, black hawthorn, some species of currants, and occasionally american licorice-root, hemp dogbane. A vine common in riparian areas is western virgins-bower. In mountain meadows one finds small-leaved Laurel, bog Labrador-tea, and willows.
