This is just a selection of our many native species, favoring those that are easiest to grow in average conditions and excluding the hard-to control.
Aquilegia formosa / WESTERN COLUMBINE
Delicate and distinctive perennial for shade. Divided, blue-green leaves and graceful red and yellow flowers nodding atop wiry, branching 3-4 ft. stems. Drought-hardy, but blooms longer where moist.
Aruncus dioicus / GOAT'S BEARD
A tall, bushy perennial with several stems arching out from the ground, 4-6 ft. tall in bloom. Airy leaves are divided into may toothed leaflets. Tiny white flowers arranged in large, nodding plumes make a graceful show in early summer. A real beauty that needs a moist, partly shady spot.
Aster chilensis / COAST ASTER
Bouquets of summer flowers in shades of lilac blue on a bushy 2-3 ft. tall plant. Grows wild on coastal meadows; easy and drought hardy in gardens.
Camassia/ CAMAS LILY
Starry flowers in shades of blue are arranged along sturdy stems above a clump of narrow leaves. The great camas (C. leichtlinii) grows 3-4 ft. tall with light blue flowers; common camas (C. quamash), is half as tall, with deep blue flowers. Both are variable, sometimes white. Easy to grow, they like moist soil in spring, dry in summer.
Carex tumulicola / FOOTHILL SEDGE
Of our many sedges, this one is among the most drought-hardy and adaptable. Thin, bright green leaves form a dense 15 in. mound, with wiry flower spikes above that. Evergreen and always attractive, it makes a great meadow or even a formal edging, in sun or light shade.
Dicentra formosa / WESTERN BLEEDING HEART
Deciduous perennial carpeting patches of forest with delicate, dissected, pale green leaves up to 12 in. high. Soft pink, rose or white flowers nod from 12 in. stems in spring, and often into summer where moist. Charming and indispensible for shade; more vigorous than it's delicate looks would suggest.
Erigeron glaucus / SEASIDE DAISY
Evergreen mats of broad, blue-green leaves make this a decent groundcover. Add to that a nearly year-round crop of fat, lilac daisies on short stems and you have a fine landscape plant. Give it sun and sandy soil.
Erigeron speciosus / CASCADES FLEABANE
Aster-like flowers in shades of lilac blue to rosy pink cover rounded, leafy mounds 2 ft. tall in summer. This native is so garden-worthy it is the parent of several cultivars. Good in sun or part shade.
Eriophyllum lanatum / OREGON SUNSHINE
Too rare in gardens, yet easy to grow in sun and sandy soil. Deep mats of divided, wooly gray and white foliage spread 2 ft. wide. Bright golden yellow daisies on short stems make a brilliant glow for many weeks in spring.
Fragaria chiloensis / COAST STRAWBERRY
Long popular as groundcover, this evergreen needs well drained, preferably sandy, soil to thrive. Its glossy foliage is sprinkled with white flowers in spring, but alas, it seldom fruits in cultivation. It does well in sun or moderate shade.
Fragaria virginiana / BLUELEAF STRAWBERRY
Little known except to hikers, this strawberry is another nice groundcover, notable for its blue-gray foliage. Typically evergreen west of the Cascades, it spreads as strawberries do to form large mats. Tiny but luscious berries are a bonus. Wants sun, good drainage.
Heuchera micrantha / SMALL-FLOWERED ALUMROOT
Mats of rounded, lobed, shiny leaves make good evergreen cover in shade or part shade. Tiny cream flowers in misty sprays in early summer. Attractive and adaptable, but needs good drainage.
Iris douglasiana / DOUGLAS IRIS
These evergreen perennials are among our most useful landscape plants. Glossy, arching strap-shaped leaves make broad clumps 12-18 in. high. Typical iris flowers in patterns of white, lilac, blue, purple and cream just clear the foliage in April or May. Hybrids with this iris and other Pacific Coast species- the Pacific Coast Hybrids- extend the color range into yellow, rust-red, mahogany, burgundy, amethyst, peach, etc.
Penstemon serrulatus / COAST PENSTEMON
This is one of the few among our dozens of penstemons that is really easy to grow. Makes a bushy clump of leafy stems topped by spikes of rosy pink to purple flowers in summer. Usually reaches 2-3 ft. tall. Adapts to damp or dry situations, in sun.
Polystichum munitum / SWORD FERN
So common, yet such a good plant. A large evergreen fern with many 2-4 ft. fronds. Great as a large scale groundcover, fine in small groups with other ferns, mahonia, rhododendrons, almost anything shade-loving. These will even grow in sunny rockeries!
Sedum spathulifolium / BROADLEAF STONECROP
Clinging to rocky outcrops along the coast and Puget Sound, this handsome succulent makes mats of chalky white rosettes, usually tinged pink or purple. Yellow flower clusters open in spring. Great cover in rocks or gravel in sun.
Tellima grandiflora / FRINGECUP
Evergreen clumps of rounded, scalloped leaves make a nice groundcover in shade. Tiny creamy cups along 2-3 ft. wands in spring slowly age to pink over many weeks. A lovely but overlooked native.
Tiarella trifoliata / FOAMFLOWER
This Heuchera relative spreads a small carpet of variously lobed or divided leaves over the forest floor, overtopped with a mist of tiny white flowers. Evergreen and surprisingly drought-hardy, foamflower is a charming addition to the shade garden.
Vancouveria planipetala / UPSIDE DOWN FLOWER
An evergreen groundcover from redwood country, making small patches of glossy leaves that are divided into triangular leaflets. Tiny white flowers suggesting parachutes dangle from wiry stems. A fine, small scale cover in shade and woody humus. Unfortunately scarce in nurseries.
