Canna 'Wisley Dwarf'

Canna ‘Wisley Dwarf’

We don’t grow very many Cannas but this one got our attention. Smaller than most it rises to just 3′ tall. In all of summer it produces masses of curly hot orange open flowers. Very pretty and very vivid. The moderately sized leaves are bold but not the tour de force of most. No mind its pretty and easy to grow in RICH, well drained soil with ample summer moisture in a hot, protected position. Emerges late in spring (sometimes not until early May) be patient- Cannas adore heat and it takes a few warm days to warm the soil enough to wake them up. Spreads to form expanding clumps. Full hot sun.

Carex comans 'Olive Oil'

Carex comans ‘Olive Oil’

We found this unique foliage color in a seed batch of regular old green Carex comans. Such a cool khaki/olive color that we named it ‘Olive Oil’ and have been producing it ever since. To 1′ tall by up to 3′ wide in rich, moist soil in full sun to part shade. In summer much longer trailing stems hide little brown blooms that morph into very fecund seeds. Excellent combined with chartreuse/gold leaved plants. Great in containers. Not drought tolerant. Evergreen.

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 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.

Centaurea simplicicaulis

Centaurea simplicicaulis

This is a really good perennial that combines pretty evergreen foliage and wiry stems that rise to 8″ and open pale pink fluffy Bachelors Button flowers in late spring and early summer. The low mounding foliage is dense and remains good looking through most seasons. It requires full sun and rich, fast draining soils to establish and spread. Line paths, rock gardens, gravel gardens, hellstrips. Light consistent summer water- not at all shade tolerant. Spreads to 2′ wide in time. Perennial containers. Native to Turkey.

Claytonia sibirica

Claytonia sibirica

Lovely ubiquitous woodland flower that brings waves of glorious airy stars for weeks in late spring to mid summer. Occasionally pink the flowers most often are white. Handsome somewhat bold foliage provides a plant that is more than suited to competition on the forest floor. Often self sows and this is welcome. Plant containerized plants in spring and water faithfully through the first summer- but never boggy. Then it is yours. Let it romp among ferns, Hosta, Japanese Forest Grass for a sparkling NATIVE treat. Mix with other natives such as Vancouveria and deer fern. Very easy to grow. Blooms for a very long time and longer if we have a cool beginning to summer. AKA Candy flower. To 10″ x 10″ on average. Summer deciduous and emerges early in spring. Not bothered by pests. Forms spreading colonies in rich, humus enriched soil in part shade to shade. Locally native in the Portland city limits.  Oregon native plant.

Clethra barbinervis 'Takaeda Nishiki'

Clethra barbinervis ‘Takaeda Nishiki’

Variegated form of Japanese summer sweet with amazing white splashed foliage and masses of powerfully fragrant white flowers all summer. To 10′ tall moderately fast in part shade to full sun in rich, moisture retentive soil. Regular summer water. In time it forms a trunk that displays mottled exfoliating bark which is very pretty. . Wonderful woodland tree that endures full sun with regular irrigation. Light yellow fall color. Graceful at all times. Nice branching pattern in symmetrical whorls. The clusters of flowers dry and cling to the tree in winter. These can be removed by the fastidious gardener or left to hang and decompose with the effect of spanish moss.  Blooms continuously most of the summer. The clusters of pendant white flowers emit an intoxicating perfume that is most notable on warm to hot days. It will perfume the entire garden- its not a cloying sweetness either but a much more sophisticated aroma that has you seeking more. Water regularly, not drought adapted. Lovely, lovely specimen tree. Avoid hot dry sites.
