Subalpine Rose Spiraea is native to the higher elevations of the the Cascades. Above 4500′ in sunny, moist glens it makes carpets of deep rose pink umbels from low rounded shrubs. To 30″ tall by 4′ wide in garden conditions, Rich soil with regular irrigation. Moderately fast growing to this dimension. The emerging soft green leaves take on hints of blue as they mature. Bloom at low elevation is May-July but in its highest native haunts bloom can be delayed to late summer. Deciduous shrub with wonderful orange/ red fall color if brief. Easy to grow native garden plant with regular irrigation. Established plants can take deep watering every two weeks. Remember that this as with all Spiraeas have little tolerance for drought and they don’t necessarily wilt going straight to crispy (a look not as fixable as wilting). Mulch heavily for the first few seasons. Avoid blasting, reflected heat and and hot dry situations. Wonderful combined with Rhododendrons and Azaleas for similar cultural conditions. In its native haunt it can be found with Pacific Rhododendron, Helenium, Delphiniums and Veratrum. I’ve never seen it afflicted by disease. Watch for aphids, hose those off if they appear. Beautiful in bloom. Very cold hardy. Oregon native plant.
This is a charming hardy, deciduous shrub with quite a few fine attributes. In late winter to early spring red flower buds line the arching fine stems and open to white/light pink. The effect is a classic apple blossom scheme. The fine leaves are thin and and a pleasant fresh green in summer. I think its finest hour is autumn when the whole shrub becomes a glowing ball of red/ orange/ pink. The chemical that causes the the pink in the flowers is most evident in the fall color. Tough rounded and then arching shrub of fine texture. Blooms on wood from the previous season, prune directly AFTER blooming if necessary. Size is somewhat dependent on irrigation. To 4′ x 4′ in 5 years in rich to average soil with regular summer water to establish. Then just avoid severe aridity. Long lived, cold hardy plant that is best with a hard pruning every 6 or so years to refresh. Good for wild areas, not deer resistant but admirably adapted to dryness. Excellent performance in the Columbia Gorge and east of the Cascades. Mix with Spiraea betulifolia var. lucida for summer bloom but a simultaneous spectacular long show in fall. Native to Japan.
This is our local form of the Pyramid Spiraea an attractive naturally occurring hybrid between two local species. Spiraea douglasii (dark pink flowered) and Spiraea betulifolia var. lucida (white flowered). Its a larger plant and much more controlled than its parent S. douglasii and it inherits some of the drought adaptation of Birch leaf Spiraea. To 5′ tall and 4′ wide this upright growing shrub produces pyramid shaped inflorescences of the softest pink- intermediate between the two species. This form was found just east of Portland. Full sun and occasional deep soaks in dry summers. Tolerates part shade at the expense of a tidy, upright habit. Blooms on wood from the previous season, prune if needed after flowering. Adaptable to wild areas. Deciduous shrub that turns to tones of yellow and flaming orange in mid autumn. This twiggy shrub would make a great hedgerow plant. Blooms late May to early July. Flowers turn to tan seed heads that persist on the plant. Cold hardy and not difficult to grow. Not bothered by pests or disease. Not fussy about soils adaptable from sand to clay. Oregon native plant.
Waratah of Australia, this extraordinary shrub produces some of the most alluring flowers in the flower kingdom. A tall growing evergreen shrub with handsome leaves. In spring and often again in late summer crown shaped flowers emerge purple and open to circular red flowers at the branch tips. These are seedlings of Telopea x ‘Braidwood Brilliant’ which is a hybrid selected for excellent cold hardiness for the cut flower trade. Protea- which means you should avoid fertilizer and too much compost. Rich to average soils- pure loam is ideal in a protected location in full sun to part shade. Avoid reflected heat. Light summer water. Not the easiest shrub to establish but the care and patience are worth it in the end. Cold hardy to approximately 5ºF. Protect from subfreezing wind. Amazing cut flower that lasts for weeks in a vase- if you can spare a stem. Excellent performance at the Oregon Coast. To 12′ x 8′.
Xera Plants Introduction.
Big form of the already big Japanese Rice Paper plant. Enormous 3′ wide leaves look jurassic and erupt in spring from seemingly spindly bare stalks. Fast growing deciduous shrub/tree that also suckers to form wide colonies. To 18′ tall in 5 years with multiple trunks in deep rich soil with regular irrigation. Full sun to part shade. Be aware that this plant travels. It moves stealthily underground and can be many feet away from the parent plant before you notice it. The more root disturbance the more errant suckering. Give it room and respect. Light summer water. Almost blooms each autumn before running out of heat and daylength. Bare sticks in winter.
Silver Germander is a wiry shrub with gray foliage and even lighter gray/white stems. All summer it bears pale blue small flowers with a prominent central lip. Traditionally used in topiary or as a trimmed hedge, it takes amazingly well to heavy shearing. It responds by becoming incredibly dense. Its malleability leads people to also trim it into any whimsical shape they can dream of. Full sun, average, well drained soil. Little to light summer water when established. Requires full sun and a hot position with protection from subfreezing wind. Classic mediterranean shrub. Grows as well at the cool coast as it does in the hot inland areas. To 4′ x 4′ if left unpruned.
Himalayan Whortleberry. Cool, compact, slow growing very nice looking evergreen blueberry relative from the Himalayas. Small round leaves are dense on the stem and very symmetrical. New growth arrives bright red before settling to deep green. In spring striking red and white striped pendant flowers arrive in clusters. If pollinated they produce small blue/black tasty berries ( so far this has been rare for us). To 3′ x 3′ in 6 years for full shade to part shade in rich, well drained soil. Regular summer moisture. Excellent performance in a woodland or along a margin. Avoid dry compact soils which it intensely dislikes. An annual application of mulch will keep the roots cool and moist during the heat of summer.
Evergreen huckleberry is a fantastic native broadleaf shrub. It is well adapted to shady sites and will accept full sun with regular irrigation. Well established shrubs require less water. Rich, humusy woodland soil is its favorite haunt and it will grow moderately fast to a rounded outline of 8′ tall and 6′ wide. The new growth is a beautiful salmon pink before changing to deep green. In spring and early summer small white urn shaped flowers are pretty and transform into tasty black fruits in autumn. Amazing in muffins, pies.It has an interesting natural distribution along the immediate coast in most of Oregon but veering inland at Douglas County to almost the Cascade foothills. In Puget Sound it seems to be most prominent within sight of salt water. Easy to grow good garden plant. Oregon native plant.
Unique and we think very pretty evergreen Viburnum. Small perfectly round leaves are placed in threes around the stems. In summer the terminal branches host clouds, or cymes I should say of tiny white flowers. They have no fragrance but are pretty to look at.. Moderately growing rounded shrub of great symmetry to 4′ x 6′ in 7 years. Full sun to part shade in rich, well drained soil with light but consistent summer moisture. Takes very dry conditions when established. At first glance this does not look like a Viburnum- which is charming. Its a very pretty dense growing first rate evergreen.
Oregon Viburnum or Western Way Faring tree is a moderate to large native deciduous shrub. It stretches a little bit into W. Washington where it is rare but its primary populations are in western Oregon and south into N. California. Its found in moist to dry woods often on the margin where its can get at least half a day sun. It also thrives only much larger and lankier in outline in the shade. It easily tolerates winter inundation but is found on well developed soils in upland situations as well. Its common associates in the wild are Oregon white oak/Quercus garryana, Oregon Ash/Fraxinus latifolius, Cornus stolonifera. Leaves are round, glossy and scalloped and are very handsome on a well proportioned fountain shaped shrub. Shorter in full sun, taller in shade. This plant needs just a modicum of light watering for its first year and once it is thoroughly established you can set it free. In late spring off white cymes of flowers have the fragrance to me of raw potatoes. We had a large specimen of this shrub in our back 40 where I grew up near Eugene. In certain years it can produce quite a fall show with orange/red tinted leaves and translucent blue fruits. Blooms on wood from the previous year. Prune if needed AFTER blooming has ended. June. To 5′ tall in the sun to much taller in shade. Protect young plants from deer. Oregon native plant.
