Sedum sediforme ‘Spanish Selection’

A really good Sedum that I got from a friend who collected it on the Iberian Peninsula in the Spanish mountains. Very soft blue gray foliage is shaped like pine needles lining trailing stems. Forms a good ground cover very fast. In summer 10″ vertical stems support clouds of soft off white flowers. Very different from so many other Sedums that bloom yellow. This soft color is very effective in the garden and of course draws pollinators from miles around. When spent the stems remain erect and turn gray- they may easily be collected by simply giving each a soft tug- or a whole a handful and they will break cleanly. Full sun to very light shade. Average to enriched soil that is not compacted. Good looking year round appearance. Not quite as dense or prolific as Sedum reflexum but still good. Slopes, between shrubs, as competition for weeds. Roots along the ground as it grows. Moves with ease and may be used as a temporary place holder while you think of what to plant next. Simply scoop up the foliage and move it to another place. Actual planting is not necessary. Share with friends. Great in seasonal as well as winter containers. To several feet wide. Light summer water or none when established. Easy plant.

Sesleria autumnalis ‘Campo de Azul’

An autumn moor grass with distinctive differences. Very blue upright, stiff foliage forms a large expanding clump. In mid summer through autumn (and beyond) 18″ straight vertical stems support gray/black flowers frosted with light yellow pollen. Excellent appearance year round for an evergreen grass to 1′ tall and 2′ wide in several seasons. Well drained average to enriched soil. Light, consistent summer water in full sun. Excellent massed, plant on 2′ centers. Flowers slowly decay over winter and spent stems may be cut away. Refrain from cutting this plant back to the ground. Winter damage will be covered quickly by new growth in late winter to early spring. Establishes quickly. Cold hardy below 0ºF. Native to Italy/Croatia- its adapted well to a summer dry climate. Nice looking grass.

This is the true Varnished leaf Spiraea that is  native in the Portland area. The large fluffy inflorescences – almost furry and true  tiny petals.   This too is a wonderful shrub that is tolerant of a host of situations. It is native in the Portland, city limits and knowing where it grows will lead to success with this easy going native. To about 3′ x 3′ and increasing laterally by stolons. This low deciduous shrub is primarily  a resident of high douglas fir overstory, but it can alsmost make appearance at the wetter end of oak savanna. The flowers appear from late spring to early summer. They are natural landing pads for butterflies even hummingbirds appear.  Best in an open north exposure with regular H20 then the following year less to none. Its naturally one of the most drought adapted of this genus. Give this plant room to spread, interweave its way around Holodiscus and Symphoricarpos, Gaulthria shallon. in rich soil ( to begin its life and establish)  Fall color can be yellow to peach and can also not really happen. Wonderful plant. Oregon native plant.

Symphoricarpos albus

Common snowberry is very widespread in our state and is found in a host of biomes This small, deciduous, suckering shrub begins spring with leaves of the freshest green, so fresh they flutter on the late spring early summer breeze. After several weeks of foliage the small white tinted pink flowers are shaped like small bowls and line the stem at every leaf axil. These morph into plush, plump pure white berries that are quite a bit larger than the relatively insignificant flowers. The berries (drupes) are perched in groups on the stems. Their pure white hue is easy to spot for humans and especially birds.They relish the berries while they are toxic for humans.  To 32″ tall forming a dome shaped suckering shrub twice as wide. Water to establish the first season then none in subsequent years. Mulch heavily.  The berries last well into winter before becoming animal snacks. The gray thin arching stems create a haze on the forest floor that becomes acid green as leaves appear. Spreads by stolons underground to expand its territory. Its adaptable to both upland quite dry situations as well as vernally wet spots in floodplains and fields. In the Willamette Valley its common associates are with Pseudotsuga menziesii (Douglas Fir)  Quercus garryana  ( Oregon White Oak) and Fraxinus latifolia ( Oregon Ash) as an understory component. Its tolerant of dense shade as long as its deciduous to full hot sun, Very well adapted to the driest summers. In summer the acid green leaves change to a dark blue green and are often afflicted by a strain of powdery mildew- my whole life I’ve known this shrub and I’ve never seen powdery mildew cause any permanent damage- mostly its just a poor aesthetic look for late summer to autumn. Fall color is soft yellow and brief. Branches may be carefully cut in berry and will hold them in arrangements for quite a few days. An excellent forage and cover plant for native fauna.  A great native shrub for beginners. This is the taller form of the two species that we grow. Native to the Portland city limits. Moderate deer resistance. One of our best shrubs for seasonally dry shade.  Oregon native plant.

Tropaeolum majus ‘Orchid Flame’

This has turned into one of our favorite annuals. An ancient Nasturtium variety from the 1880’s it is a chameleon of a flower in color. Neat round, water lily leaves are distinctly blue on a compact cultivar. Almost instantly ruffled fragrant flower appear above the foliage. They take on various colors, often starting yellow sanguineous red will begin in the creases of the petals and spread throughout the flower. It appears to be dependent on the amount of heat. So, all matter of colors dominate on the flower as heat waxes and wanes. This selection appreciates full sun but not in a blazing position. Avoid the heat of reflected walls. An open north exposure is ideal. To 8″ tall x 1′ wide. Great in containers. Nice, exotic cut flower and fun to grow. Blooms all summer and cooler weather and fall rains re-invigorate the plant and sets an explosion of flowers that persist until a truly hard frost. Charming nasturtium that we love. Consistent summer moisture in AVERAGE, well drained soil.

Yucca rostrata

Beaked Yucca does fantastically well in our climate and is one of the Yucca species that will form a dramatic trunk. Blue thin leaves radiate out in a perfectly round orb. Slowly rises to 8′ tall in our climate. Full hot all day sun in a warm position. Very well drained soil with light summer water during the hottest stretches to encourage growth. Occasionally, with age 4′ spikes appear holding large trusses of ivory flowers. Perfectly hardy to cold, way below 0ºF. Avoid cold wet sites- to really do well it needs heat and exposure. Not prone to bacterial leaf blight that affects other Yucca species. Good air circulation. Lives happily in large containers for eons. Focal point in many of the best gardens in our region. High deer resistance. Evergreen.
