Roemer’s Fescue is a native bunchgrass found on upland prairies and slopes throughout the PNW. In the Willamette Valley it survives on the upward margins of woods, often under Oaks and accompanying California fescue. Roemer’s Fescue has much finer leaves and a tighter clumps than Festuca californica. Its immediately identifiable by this thin blue green foliage. A cool season grower it spends the winter in its freshest and lushest state by the onset of summer drought it has already gone cere (dry dormant). To 8″ tall and spreading. 1′ spikes with tan flowers appear in late spring and remain erect until the entire plant goes summer dormant. With regular water and good drainage this grass will avoid summer sleep and remain green and lush. A common component of Willamette Valley Oak Savanna and losing ground to invasive weeds. Excellent underplanting for drought adapted shrubs, or for the garden/wild lands interface. It spreads quickly by seed- its from here, you should expect that so keep it away from highly manicured areas. Its habitat in the Willamette Valley has shrunk to almost nothing. Bring this pretty native bunchgrass back to our gardens. Admirable lawn substitute. Evergreen. Oregon native plant.
A west coast native grass that ranges from British Columbia to Southern California- usually near the beach. This form is exceptionally blue and so pretty as a year round evergreen presence. To 9″ tall and spreading at a measured rate by stolons slowly expanding the plant to several feet wide. Forms an incredibly dense cover and weeds will seldom compete with this climate adapted grass. In late summer and not profuse 8″ stems hold gray floral spikes. This is along lived, easy to grow grass that does not die out in the center or poop out after a few years. In fact it would make an admirable lawn substitute. This form is from Humboldt, County in CA and was named for the small town where Greg lived as a child- so we had to grow it. And damn it turned out to be a fine, evergreen, native grass. Full sun to light shade and little to no summer water once established. Not fussy about soil and not a rambunctious thug unless soil is overly enriched- instead give it oxygenated average soil. Excellent among drought adapted shrubs and especially nice interplanted with Pacific Coast Iris. Fine dense foliage is bright blue in summer turning to more of a greenish hue during the cooler months. Excellent winter appearance. High deer resistance. Oregon native plant.
The all gold form of the legendary Japanese Forest Grass. Forms spreading clumps of arching gold foliage. A bit more upright than the variegated variety ‘Aureola’. To 2′ tall and 3′ wide in rich, well drained soil with regular summer moisture. Full sun (with water) to part shade. Fall color is rich amber. Winter deciduous. Mixes in a contrasting way with the glossy deep black/green foliage of Beesia and provides the texture and grace to many bulky Hosta plantings. Appreciates an annual application of all purpose fertilizer. And it appreciates well amended soil. Water regularly for the first summer to not only establish but grow the clump. A pacific northwest classic by way of Japan. It also emerges just in time to hide the fading foliage of spring bulbs. Planted in close proximity smaller Narcissus, Muscari, and Crocus will have foliage neatly disappear as the clump of forest grass expands. Very good under deciduous trees.
Legendary grass in the PNW. This striking form of Japanse forest grass has gold leaves striped in darker green. A clump forming perennial that arches gracefully. Lower growing than our other cultivar ‘All Gold’. Spreading to 3′ across in time this long lived deciduous beauty is indispensable in our climate. Rich, well drained soil with regular summer moisture. Full sun (but not reflected heat and with water) to part shade to quite a bit of high overhead shade. Woodland, walkways, borders, everywhere really where you need a touch of graceful elegance and a vivid color to brighten up dark days. Turns russet tones before losing its leaves in the fall.
Spikey evergreen Iris relative that forms substantial clumps quickly. This species has leaf blades in a fashionable taupe. To 14″ tall and eventually getting wider. In summer three petalled pure white flowers appear on panicles within the foliage. These are followed by small showy yellow berries. Full sun and rich, well drained soil with regular summer water. Sharp drainage is important for cold hardiness. Put this on a hillside or in a gravel bed. Water faithfully to establish. AKA White flag. Native to New Zealand. Great in containers. Excellent performance at the Oregon coast.
Orange sword. Striking spiky ever orange monocot in the iris family. Forms upright spreading colonies in rich, well drained soil in full sun to light shade. The curving thin blades color brilliant orange with any kind of environmental stress. Hardier to cold when established. Runs by stolons give it room. In summer with in the evergreen foliage three petalled pure white flowers transform into yellow berry-like structures. Grows well in pots if left undisturbed and protected below 15ºF. In extreme cases it can freeze to the ground (below 10ºF) and will vigorously return. Avoid boggy situations. Moderate deer resistance.
Snowy woodrush is a great woodlander and has many seasons of interest. The thin arching blades on this clump forming plant are softly veiled in white hairs that gives a softness to the clump. To 10″ tall and as wide in a season. In late summer 2′ tall spikes appear and produce snowy white flowers. They sway in the breeze. A mass planting of this in bloom is magical. Rich, moisture retentive soil that drains in part shade to shade. Takes sun with regular water but nothing hot. Excellent long lived perennial. Can self sow when very happy. The hairy seedlings are easy to spot and move- or give away.
We’ve been impressed with this evergreen, ever lovely, ever symmetrical sedge from Europe. Tightly clumping deep green plant to 6″ tall x 11″ wide in time. Rich, moist, well drained soil is ideal. Protect from blasting sun and reflected heat. Excellent performance in woodlands, sunny, irrigated borders. Imparts both a natural look but its habit is so symmetrically round that it also gives a modern feel. May be massed for a profound soft effect. Regular summer water- especially during heatwaves. Excellent performance in containers. Easy to grow. Evergreen- but it can look a little burned if we have extreme cold- not to worry new growth quickly hides any tatty leaves in spring. Avoid dense, dry shade, dappled overhead shade is ideal. Deep green appearance year round.
Sylvatica- of the woodland and this woodland evergreen workhorse of a sedge is both easy to grow and always good looking. Forms bold rosettes of 1/2 wide deep green stems to about 2′ across. In early spring 1′ spikes hold metallic tan flowers. Very pretty. Full sun to dense shade in rich to average well drained soil with light summer water. More water will be needed the more sun it gets to remain deep green. Easy to grow and excellent massed for a uniform if somewhat wild look. Remove spent flower spikes to prevent seeding which will occur in open disturbed sites that you irrigate. These seedlings are easy to spot and move and it never becomes a pest. Long lived. Adaptable to very dry conditions in shade.
This! This is one of the coolest sedges for winter displays. It virtually glows in yellow/chartreuse and spreads to form large patches. Adaptable to both full sun (with water) to dense shade. it holds its gold coloring in shade but is more conspicuous in the cold months. In summer it turns lime green and can be site where it fades into the background. In early spring 1′ chartreuse stems display excellently contrasting warm, metallic brown flowers- they are quite showy and come in great quantity. Excellent in rich to average soil with regular summer water. Full sun (but not reflected heat) to dense shade. Very adaptable to dry shade conditions. We love this evergreen workhorse of a sedge that virtually glows. Great en masse or as a simple single glowing patch. This species of woodland sedge is native to Europe. Excellent plant.
