Ratibida pinnata

The biggest black eyed susan daisy of them all. Towering to 7’+ the sturdy straight stems of this hardy American plains native perennial displays very large yellow flowers with drooping petals reflexed away from a prominent black central cone. The thick stems rise up from a low mound of foliage. Blooms all summer long and often into October. Loved by pollinators of all kinds it also makes a really cool and surprisingly long lasting cut flower. Put this beauty in the back of a border where its sunny yellow flowers can wave to the sky. Light summer water in any well drained soil. Full sun to avoid flopping.

This short lived, very showy perennial is tough as nails. This strain enchants with huge flowers that are almost always single but come in tones from black to yellow, brown, orange, and red.. They immediately remind me of a blanket made by native Americans.  To 28″ tall ( compact ) with enormous flowers up to 5″ across. They come in a profusion from mid summer to early autumn. This strain has a natural life span of 3-5 years – but it does re-sow itself in open and opportune places. Open  soil that has been slightly enriched with compost / fertilizer. Full sun and regular water until fall rains take over. Mix with other sunset orange/ brown toned flowers. I pick the searing true red of Salvia ‘Royal Bumble’ as sell as the soft green spikes of Kniphofia pumila both will bloom simultaneously  with the Rudbeckia Excellent in summer containers and beloved for its long bloom time. Remove spent flowers for the first few rounds to encourage more bloom. leave the last round  to be pollinated and set seed. Excellent pollinator perennial. Regular water for the first season , less the following year. Some deer resistance.

Rudbeckia occidentale

Our native coneflower found in the Cascades. Look! It forgot the petals. Yup thats our boy. Clump forming tall perennial for moist sunny sites. Rich, soil with ample humus. Easy to grow in a perennial border where you can take advantage of the austere look of the flowers, when they come en masse at the end of 30″ stems they are something to behold. Very good cut flower and it goes with a very modern aesthetic. Full sun. Completely deciduous in winter. Oregon Native Plant.

Solidago canadensis var. elongata

Our own west coast form of Golden Rod which can be found in vernally wet locations or even fence rows. Vigorous, strong growing perennial that erupts in plumes of golden flowers from August to October.  Spreading via runners it can take up quite a bit of space in lush environs. Best to grow it in un-amended soil with light summer water. Full sun to very light shade. Handsome mid-green leaves line nearly woody stems to 32″ tall. Spreads as far as you let it. Sleeps the first year- LEAPS the second and you have been warned. That having been said its a wonderful romping native perennial for late season pollinators. Its very easy to grow and long blooming. I wouldn’t plant a Willamette Valley meadow without this plant. And my, do you get good bugs. VERY good bugs. Lightly fragrant flowers are great in late season arrangements. Best to pair it with a companion that is just as rambunctious- we select Symphyotrichum subspicatum our native Douglas Aster. Not only do they match each other they make a splendid floral complement and bloom simultaneously. And it will triple the amount of pollinators. Foliage can take on orange/yellow tints in late fall. Cut back in early spring. – but fairly self sufficient.  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.

Outstanding form of New England Aster that has the most intense deep purple flowers on a non-splitting compact plant. To 18″ tall by 22″ wide, it arrives in bloom in September and continues through October. Rich soil with regular irrigation in full sun to very light shade. An excellent late border perennial and it would be located in the middle to the front of a border. The dense, compact habit of resists splitting in our first fall rains- not all cultivars do. Loved by pollinators including natives. Spent stems can be left erect through winter as food for birds and insects. A basal rosette of green leaves will just be emerging at the base. Easy, reliable, hardy perennial.  The flower stems last quite a while in a vase. Mix with the pink clouds of that outstanding fall blooming grass Muhlenbergia riverchonii. Very long lived. Mildew resistant. Good deer resistance.

Symphyotrichum subspicatum ‘Sauvie Snow’

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.
