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.
For flowers in this genus this is THE plant. Upright growing plant from a clump that rises to 2′ and produces multiple spikes of bright coral colored flowers. They are arranged in symmetrical whorls up the stem. Loved by hummingbirds who constantly seek nectar from the flowers that appear from late spring to late summer. When flower spikes are spent simply cut them away and water and more will arrive. Very easy to grow long blooming perennial for full sun to part shade in rich, well drained soil with light but consistent summer water. Very drought adapted when established. Works well in borders and even seasonal containers. The leaves have a very familiar lemon lime aroma. Dies to a low clump of foliage in winter.
Curious and pretty small perennial that has lovely leaves that have symmetrical black veins. As the plant expands it sends up spikes clad in frosty hairs around violet purple flowers. The don’t exactly go straight up but wind around a little bit. This gives the whole plant an overall haze that is truly fantastic. Appreciate sunny dry environs with sharp drainage but as rich of soil as you can muster. Ideally it finds a home in a dry border or rock garden. Winter deciduous perennial to 18″ x 18″ in a season. Blooms repeatedly all summer. Light summer H20 and drought adapted when very established. Mixes well with Cranesbill (Erodium) and Scutellaria suffrutescens. Pretty little cut flower that acts as a boa in a small arrangements. Very good butterfly and pollinator perennial. Absorbs blasting hot locations. Flowers when spent turn to light brown wands of fuzz- this extends this plants season of interest.
Creeping snowberry is widespread in western Oregon and indeed throughout the state. Its a low suckering deciduous shrub that can occupy large areas. To 30″ tall spread is indefinite in rich to average soil with regular water for the first year to establish. Mulch is extremely beneficial and will suppress weeds for the first few years which can arrive in the middle of a patch of this spreading plant. Leaves are fresh green in spring turning blue green with the heat of summer. Small pinkish flowers occur in late spring and morph over the summer into plush white squishy berries. They line the bare stems and are showy until birds make off with them or they remain and rot. The berries are toxic for humans. Fall color is light yellow to very little. Common on undisturbed slopes on the edges of the valley and in the eastern foothills of the Coast Range and western Cascades. Snow berry is often afflicted with powdery mildew in the driest parts of summer. No harm will come to the plant. A wonderful habitat plant. Oregon native plant.
Pacific Aster is a Xera favorite late blooming native perennial. Masses of thick soft periwinkle flowers with a yellow center on an upright growing plant to 30″ tall forming an expanding clump. Blooms which are loved by native pollinators – they instantly appear, you don’t even have to be patient- are a soft color and open on the plant first on top and then down the sides eventually filling in. Its a cloud of periwinkle. Sometime afflicted with harmless powdery mildew. This is more of a problem near winter and afflicted material can be cut away and disposed then. Otherwise leave it standing and dead to thrill bush tits or some creatures like that. Rich soil with deep infrequent irrigation during summer. Once established it can perform reliably on rainfall alone (it will happily accept regular irrigation as well). Excellent mid-border late perennial that is fantastic with the green flowered late blooming Kniphofia pumila, and Golden rod Solidago canadensis elongate. Long lived. It may be divided after several years. This plant is common around the Pacific Rim in temperate to colder regions. Its natural range is enormous- notice the specific epithet refers to its Chilean origin,, it is just as native and prolific on the Oregon coast. Often found at the edge of woods or scrublands in the transition to grassland/ dune lands. Its common associates in habitat are Fragaria chilense (another Pacific Rim resident)- we grow the variety ‘Aulon’, as well as Pacific reed grass ( Calamagrostis nutkaenasis). Long blooming. ( AKA Chilean Aster- but that is confusing as it is native in Oregon as well. Great performance at its native Oregon coast on sand to clay soils. Oregon native plant.
Pacific Aster. Our selection of a widespread beach aster species that circles much of the temperate Pacific Rim. This form tops out at a compact 30″ on an upright plant that forms expanding clumps in rich to average soil ‘Short Sands’ is a purple form from seed of a very dark purple specimen that Greg found. It is by far the darkest purple that we have encountered in this species. The majority are white to very light lavender. Most often its habitat is adjacent or very near the coastal strand. Its adapted to all kinds of soils from sand to clay and it appreciates deep infrequent water during the summer season. Blooms begin in August and open until mid November. This aster is often seen along the sides of HWY 101. In fleeting glimpse you can capture small periwinkle daisies late in the season. A pollinator master piece. All sorts of natives recognize this showy perennial. Full sun to light shade. It seems to be most vertical in full sun and average soil. Over amended soils, too much water, or too much shade will lead to a splaying flop. The flat upturned daisies come in rows of two for a fuller look and are a natural landing pad for butterflies. Winter deciduous, very tolerant of dry conditions when established but does better with deep infrequent summer drinks. Cut back hard in spring- a new batch of leaves will just be arriving. This sophisticated native is at home in pampered borders or wild areas. Associated plants in habitat are Mianthemum dilitatum, Calamagrostis nutkensis, and Vaccinium ovatum. Its habitat is dwindling as Everlasting Pea (Lathyrus latifolius) and Ox Eye Daisy (Dendranthema) have crowded this special plant out Excellent garden plant. Oregon native plant

Hall’s Aster might as well be known as Willamette Valley Aster as this charming smaller perennial is found primarily there. To 20″ tall and spreading to form a wider clump this native aster begins blooming in August and continues into Autumn. The small daisy flowers have rays that are primarily white, though light pink and lavender are also seen. The reverse of the petals is always a darker color- primarily very light lavender. Excellent native pollinator plant for late in the season. Full sun to very light shade in rich to average soil. Adaptable to xeric clay soils that dry in summer. In the garden deep infrequent soaks will yield the healthiest and most floriferous plants. Spreads moderately underground by stolons. Not bothered by deer. Nice little cut flower as filler for bolder arrangements. Climate adapted perennial that is a native for a Willamette Valley prairie. Not as vigorous and space consuming as Symphyotrichum subspicatum – Douglas aster. Hall’s aster fits in much smaller spaces. Easy to grow, winter deciduous. Associated plants in the wild are Sidalcea m. ‘Virgata’, Eriophyllum lanatum, Achillea millefolium. Takes intense dry conditions with establishment. Oregon native plant.
We selected this form of our locally native Douglas Aster for its snow white flowers. The species in our area ranges from blue/lavender/blue-white. So, this is a nice color break. One of the very best pollinator perennials that we grow. In bloom from July-October it is virtually swarmed by every flying insect you can imagine. A constant buzz of activity. This is a large, rambunctious perennial that is not good with delicate neighbors. Douglas Aster belongs in the wild where it can consort with other similarly overly adapted natives. Virtually any soil in full sun to light shade. In bloom it rises to nearly 30″ and the spread is nearly indefinite This is a rugged perennial for tough sites, even areas submerged during the wet season. Not a bad cut flower. Mix with large ornamental grasses such as Miscanthus sinensis ‘Morning Light’ or Panicum virgatum ‘ Heavy Metal’. Mix with native shrubs- Mahonia aquifolium, Oregon Grape and Holodiscus discolor ‘Ocean Spray’. Drought adapted when established but it appreciates a soak now and again to prolong the bloom period. Oregon native plant.
Xera Plants Introduction
One of our color selections of the locally native Douglas Aster. This cultivar originates from seed collected on Sauvie Island. This is the predominant wild Aster of the Willamette Valley. A boisterous long blooming perennial at home in wild areas. Rich to average soil with light summer water. Blooms- in this case, periwinkle blue open in early August and continue unabated to October. They are beacons to all pollinators and are constantly in motion as they bloom. To 32″ tall forming wide patches. Runs by underground stolons. Nice cut flower. Wetland remediation, forest verges, denuded road cuts. Those are jobs for you Douglas Aster. Oregon native plant.
Xera Plants Introduction.
Locally native on our nursery site Fringe Cups or Fairy Bells as they are commonly known are a spreading perennial for moist shady sites. Low mounding maple shaped leaves cover the ground densely and in late spring vertical spikes appear to 18″ tall and sport rows of small green cup shaped flowers which change to white and finish with tints of pink. Closely related to Heuchera and thrives in the same conditions. It will even take full sun in moist conditions. It is a background plant because it often suffers from powdery mildew late in summer which is mostly just ugly and I’ve never seen harm to the plant. The drier the conditions the worse the affliction. Good air circulation helps but its best to just accept that this is how this native perennial rolls. Semi-evergreen in winter. Woodland borders, shady containers. Very easy to grow. Often grows with Claytonia as seen below. Flowers emit a sweet fragrance. Oregon Native Plant.
