RIPARIAN SPECIES FOR STREAMSIDE GARDENING

Pictures link to OSU Department of Horticulture Landscape Plants website. 

Blue elderberry (Sambucus mexicana)

Large shrub.  Abundant blue berries are edible and make this a great wildlife species.  Spreading habit.

California hazelnut (Corlylus cornuta var. Californica)

A large shurb with branches than arc downward.  Produces edible nuts, closely related to the domestic filbert.  Primarily an upland species, but encountered in some broad floodplains. Moderately tolerant of shade and drought; probably not very tolerant of flooding.

Cascara (Rhamnus purshiana)

A large shrub or small tree, often forms thickets.  Produces black, inedible fruit.  Good wildlife species.  Moderately tolerant of shade, drought, and flooding.

Creambush oceanspray (Holodiscus discolor)

Large shrub.   Primarily found in uplands, sometimes in broad floodplains.  Produces beautiful white “sprays” of flowers, hence the names “oceanspray” and “creambush”.  Spreading habit.

Douglas hawthorne/Black hawthorne (Crataegus douglasii)

Large shrub or small tree.  Often forms thickets.  Abundant black fruits make it a good wildlife species.  White flowers in spring.  Moderately tolerant of poorly drained soils.  A related species, English hawthorne, is also found in the Rogue valley and is considered an invasive species.

Douglas maple (Acer glabrum)

Large shrub or small tree.  Attractive foliage and fall colors.  Found on relatively moist sites near streams.

Hinds walnut (Juglans hindsii)

A locally rare species, found in scattered locations along Bear Creek.  Historical information suggests the tree reached very large sizes.  Typically found in broad floodplains where subsurface moisture is available.  Although nursery stock is not yet widely available, its large size and longevity make it a good candidate for streamside plantings.

Indian plum / Osoberry (Oemelaria cerasiformis)

Medium to large shrub.  Attractive white flowers, often the first shrub to flower in the spring.  Favors relatively moist sites, not drought tolerant.

Nootka rose (Rosa nutkana)

Small to medium shrub.  Spreading habit, good for wildlife and erosion control.  Prefers wetter conditions than Woods rose.

Oceanspray (Holodiscus discolor)

Large shrub.   Primarily found in uplands, sometimes in broad floodplains.  Produces beautiful white “sprays” of flowers, hence the names “oceanspray” and “creambush”.  Spreading habit.

Oregon white oak (Quercus garryana)

A large, long lived tree, typically found in uplands but also in some valley bottom sites on poorly drained, seasonally saturated soils.  Slow growing, requires full sunlight.  Very important tree for wildlife habitat.  Acorns are used by many species, and woodpeckers excavate nest cavities (holes in the branches and trunk), which in turn are used by other birds and small mammals.

Red-flowering currant (Ribes sanguineum)

Medium to large shrub, produces beautiful flowers much used by hummingbirds and other pollinators; fruit (blue “berries”) provides food for birds and mammals.  Moderately tolerant of shade and drought; not flood tolerant.

Swamp rose (Rosa pisocarpa)

Medium shrub.  As the name suggests, grows well in swampy conditions, but also found in moist, non-wetland conditions.  Spreading habit.  Requires full sun; not shade tolerant.

Tall Oregon grape (Berberis aquifolium)

Medium shrub, evergreen.  Drought tolerant.   Attractive yellow flowers and blue berries, good for birds.

Viburnum (Viburnum ellipticum)

Medium to large shrub, forms thickets.  Uncommon.  Produces white flowers and olive-like fruits valued by wildlife.  Attractive fall color.  Many viburnum species are used as ornamental plants.

Western serviceberry (Amelanchier alnifolia)

Large shrub, spreading habit.  Produces beautiful white flowers and small blue or black berries.  Good wildlife species.  Moderately shade and drought tolerant, not tolerant of flooding.

Woods rose (Rosa gymnocarpa)

Small to medium shrub.  Pink flowers, red berries or “rose hips”.  Good wildlife species.  Very shade tolerant, not flood tolerant.
