Carex oshimensis 'Evergold'

Carex oshimensis ‘Evergold’

Common variegated sedge that is useful. The arching thin leaves have an interior of rich yellow with green lines on the sides. Dense forming evergreen tuft to 1′ tall by up to 2′ wide. Rich, moisture retentive soil with regular water in full sun to part shade. Tidy discolored leaves individually in spring- do not cut to the ground. It hates this. Gold stems support tan flowers in summer. Unfortunately, this sedge is often thrown into new landscapes and is marketed as a low maintenance carefree drought tolerant thing. Its not. It likes good care to look its best. Moderate deer resistance. Evergreen.

Carex pansa

Carex pansa

California meadow sedge is native to stream banks, and vernally wet places at the beach from British Columbia south in to Baja. A deep green winter growing sedge which each plant reaches about 18″ across and 10″ or so inches high. It flops over gracefully and has a very uniform appearance through the year with light irrigation. This is a winter growing plant that resumes growing and greens up with winter rains. In very cold weather (below 20ºF) it can take on russet tints. A FANTASTIC LAWN SUBSTITUTE where it has been used extensively for that application in California. We should use it here too. Plant on 1′ centers for a lawn (faux lawn) cover from one gallons and water regularly through the first season. No water plantings can go summer dormant but in wetter environs this can be avoided and it will remain green and verdant. Water once a week in summer to remain green.  Fantastic ground cover, slope cover as it will out compete weeds and form a uniform cover. Tolerates clay soils well, but some amending will reap rewards with a faster growing plant. Tolerates mowing very well. Oregon native plant.

Carex praegracilis

Carex praegracilis

Meadow Sedge  or Field Sedge is found primarily in meadows and grasslands east of the Cascades. An evergreen fine textured clumping sedge that is gracefully employed in mass plantings, lawn substitutes even freeway margins. Very adaptable plant for average soil with regular water for best appearance. It will make due with conditions that are much less optimal. To 14″ tall but bending immediately in a cascading motion that mimics movement by wind – even when its still. Forest margins, riparian sites. Very useful plant with good winter presence. Full sun to very light shade. Very useful in meadow plantings. Rarely seeds itself and is well behaved. And remember Sedges have edges, rushes are round and grasses like asses have holes. HEH.  Oregon native plant.

Excellent dwarf form of our native meadow sedge. To just 6″ tall it forms dense spreading evergreen patches.  In spring to summer both male and female flower spikes rise to just a few inches above the foliage. Nice looking compact plant that retains its verdancy through the winter. An admirable substitute for lawn and mowing is not necessary. This species is most widespread east of the Cascades. Its native throughout the west and this form was identified in California. Plant on 10″ centers for a modern massed ground cover. The mid green to ochre green leaves are dense and smother competition. This creates less of a hummock affect and more of a small dome. Very easy to grow. Excels in  containers. Full sun to light shade, also very high overhead shade (a tall  tree canopy). Amending the soil with compost and fertilizer will increase vigor and green appearance and quicken establishment. Spreads by slowly expanding rhizomes. Excellent between stones or pavers. Tolerates light foot traffic. Not really large enough to be bothered by deer once established. Hardy below 0ºF. This useful plant has great smaller scale, ease of culture, and consistent good looks. This would be an excellent smaller grassy component of a meadow.  Established plants can take quite a bit of summer drought.  Carex praegracilis is an Oregon native plant.

Carex siderostricha 'Variegata'

Carex siderostricha ‘Variegata’

Several things about this sedge set it apart in this genus. Broad, wide leaves are soft green on the interior but lined boldly in cream. And its completely winter deciduous. Forms a spreading clump of great bolder texture that arches all in the same direction. Very nice. To 10″ tall and several feet across eventually. Rich, moisture retentive soil in part shade with consistent summer moisture. Excellent combined with the large leaves of Hosta. Line paths or use as a graceful punctuation in a woodland. Avoid really hot sunny dry locations- it will live but it won’t look so great. Completely deciduous in winter. Turns a tawny yellow in fall before leaves disappear.

Carex tenuiculmis

Carex tenuiculmis

We playfully refer to this large sedge as rootbeer grass. Its that color of ochre brown and it shine on this plant all year. One of the hardiest and longest lived New Zealand sedges for full sun, well drained soil and light consistent summer water. To 14″ tall but spreading up to 3′ across. Trailing stems hold little brown flowers in summer. Very good winter appearance and it has survived temperatures below 10ºF with good drainage and full sun. Elegant trailing down a hillside. Very good in large containers including winter containers. Easy to grow. Moderate deer resistance. Give it room to spread.

Carex testacea

Carex testacea

Wonderful orange Carex that is a great (if temporary] garden plant. Clumping and upright then broadly arching. Leaves take on intense copper tints for most of the year. Excellent plant for containers, winter containers. Evergreen and for full sun to light shade. Regular to rich, well drained soil- average summer water. Not drought tolerant over the long haul, so at least a soak once a week in summer. To 10″ tall x 20″ wide. Give it room to reach its full dimension. Containerized plants will drape gracefully over the edge. Do not cut back hard in spring- limit your tidying to removing dead/ratty leaves. If you do have to cut it back hard then make sure you apply some all organic fertilizer and water consistently to speed recovery. Average lifespan 3-5 years. Avoid full exposure to subfreezing wind.

Carex tumulicola

Carex tumulicola

Foothill Sedge is commonly found from the central Willamette Valley south into California. A tightly clumping sedge with medium green foliage and 8″ wiry stems with attending flowers that are tan in spring/summer. In our region this plant can be found in upland situations where it is moist for at least half the year. Its also diminutive and almost hard to find in the wild. Under cultivation its an entirely different beast. Clumps are dense but expand with a pronounced weeping habit. To 8″ tall x 18″ wide for each individual plant. Good massed or as a lawn substitute. Takes mowing if its limited to once a year. Regular irrigation keeps it green and happy. Summer drought sees blades of tan as well as green and not so verdant. It does not run nor become a seeding pest- sticking surprisingly to itself. Plant on 1′ centers for a modern, mounding effect. Takes clay soils well. Water regularly to establish the first summer then taper off (continue watering if you want it to stay staunchly green).  Combines well with perennials including native perennials such as  Checkermallow (Sidalcea) and, Ranunculus occidentalis (Western Buttercup), as well as Shooting Stars (Dodecatheon) are found in closely related communities with this plant. Full sun to light shade, or high overhead shade. In California it is also known as Berkeley Sedge.  Oregon native plant.

Chionochloa rubra

Chionochloa rubra

Snow Tussock from alpine New Zealand is a clump forming grass of great grace and texture. The fine upright growing blades are a soft taupe color that shines in the sunlight. Most often the tips of this grass become cere and it gives it a wilder look. To 2′ x 2′ and a tightly clumping evergreen that increases very slowly. In summer stems clad in tan oat like flowers dangle in a pretty way from the plants top. Full sun to part shade in Well drained, rich soil with light consistent summer moisture. Appreciates an open exposure- avoid neighbors that are too rambunctious or close. Stunning in a mass planting. A great grass for our climate. Do not divide,  or move once established.

Chondropetalum tectorum 'Dwarf'

Chondropetalum tectorum ‘Dwarf’

A very nice person from a climate far colder than ours gifted us this cute dwarf Restio. And I have to say it has performed wonderfully in my garden. It froze to the ground at 9ºF- but returned in spring right away. Seems to be one of the hardiest and easiest to grow that we have encountered. Really shines in containers where you can see the sheaths on the blue green segmented stems. Rises to about 20″ tall with many stems. In summer they are topped by clustered brown flower structures. Very nice. Well drained somewhat enriched soil (for a Restio thats odd). Full sun to very light shade. Grows fairly quickly given the conditions stated above. Light summer water. Protect containerized plants from temperatures below about 20ºF. Evergreen most winters including the bummer winter of 16/17.  We’ll make as much as we possibly can. South Africa.
