Tufted hairgrass (Deschampsia cespitosa)

Tufted Hairgrass

Tufted Hairgrass is found around the world including the eastern and western coasts of North America, parts of South America, and Eurasia. It is a native, perennial, tussock forming grass found along stream banks and in moist meadows, fields, wet ditches and open areas surrounding lakes and ponds. Tufted hairgrass is a large densely tufted, course, long lived, perennial bunch grass. It has bright green foliage and a large volume of fountain-like seed culms emerging in early spring, making it highly aesthetic. Tufted hairgrass prefer open sites. This grass is rarely, if ever an under story species of temperate forest communities (Brown et al. 1988).

In the Pacific Northwest tufted hairgrass form pure stands in wet and intermittently flooded areas such as tidal mudflats and estuaries plant communities. It grows in seeps bogs, and brackish waters along the coastal waterways. It is very salt tolerant grass and, as a result, is commonly included in many restoration or re-vegetation projects where brackish water exists.

Tufted hairgrass is also a rapid colonizer of disturbed sites at high elevations (8,000 ft – Cascade & Sierra Range). Such characteristics make it valuable for reclamation of disturbed high elevation mines, ski slopes and high elevation meadows. Tufted hairgrass, unlike blue wildrye, is genetically heterogeneous, self-incompatible and requires wind and insect pollinators for effective fertilization. Tufted hairgrass should be included in wetland, restoration projects since it provides very dense nesting foliage and has a very long summer green period. It is also a valuable stream bank erosion plant where long-term stabilization is necessary, and should be established with a nurse crop (blue wildrye, meadow barley, California brome, Alaska brome) or native straw mulch for superior first year establishment.


Narrow-leaved mules ear (Wyethia angustifolia)

Narrow-leaved Mules Ear

Also known as “Narrow-leaved Mule’s Ear” or “California Compassplant”. The inflorescence produces one or more large sunflower-like flower heads at the top of the hairy stem. Large lance-shaped, basal leaves with several smaller, alternate, stem leaves.

Western bleeding heart (Dicentra formosa)

Western Bleeding Heart

Bleeding heart’s showy flower resembles a heart split open at the base, releasing its contents. It has delicate-looking fernlike leaves, with pink flowers that bloom from April to June. Bleeding heart prefers rich soil and some shade. It will thrive planted under evergreen trees or along stream banks. Heights of 26 inches can be reached though 12-16″ is more common.


Hooker’s Fairy Bells (Disporum hookerii)

Hooker’s Fairy Bells

Lovely, outwards-flaring flowers of greenish-white to cream over deep green leathery foliage, with characteristic long, drip-tips to the leaves.


Henderson’s shooting star (Dodecatheon hendersonii)

Broad-leaf Shooting Star

This bulb-producing perennial begins in late winter with thick spoon shaped leaves at the base of the plant. Showy flowers appear in early spring on top of a tall 12 in (30 cm) leafless flower stalk. Flowers are inside out with petals magenta to deep lavender to white, with a white strip before the black fertile part. It blooms February to May and is summer deciduous, dying back to the ground after the rains cease.


Woodland strawberry (Fragaria vesca)

Wood Strawberry

After flowering, rounded, egg-shaped, red edible berries appear in the late summer and early autumn. These appear to be smooth coated but are in fact covered in very short hairs, visible only at close range.

Oregon iris (Iris tenax)

Oregon iris

Iris tenax is a semi-evergreen species of Iris native to southwestern Washington and northwestern Oregon. It is known as the tough-leaved iris or Oregon iris. It occurs along roadsides and in grasslands and forest openings at low to middle elevations. One subspecies is also known from northern California.

Like most irises, it has large and showy flowers. The flowers bloom in mid to late spring and are usually lavender-blue to purple, but blooms in white, yellow, pink, and orchid shades are known to sometimes occur.

In the native garden, Oregon iris can grow large and reproduces easily, especially in favorable conditions. It tolerates winter pruning to refresh old leaves, and benefits from an occasional spring cleaning out of old vegetation.


Daggerleaf rush (Juncus ensifolius)

Dagger-leaf rush

This rhizomatous rush grows in large upright clumps. The green dagger shaped leaves fold over along the mid-vein towards the stem, similar to iris leaves.

In favorable garden conditions, this rush can grow large and spread thickly. The accumulation of previous years’ dead stems provide shelter for wildlife in winter, but an occasional spring cleaning out of dead material helps keep rushes looking fresh, too.
