Several wonderful attributes makes this a great Manzanita for widespread use. Its extremely cold hardy, a naturally occurring hybrid from southern Colorado- it can handle temperatures lower than -20ºF. Its a great size- slow growing to just 3′ x 3′ in 8+ years. The matte green foliage is dense (almost boxwood-esque) and is a great foil for the clusters of pink buds that relax to lighter pink when open. Full sun and average, unimproved soil. Water to establish then only what falls from the sky. This dainty almost formal looking shrub finds a happy home in smaller gardens, rock gardens, and thrives in Central Oregon. In time the trunks exfoliate to glossy maroon- it take quite a few years for this to be an outstanding feature. Mounded and dense for the first part of its life- expect just several inches of growth per year.. Open exposure with good air circulation. Great performance in Gorge outflow. A perfect substitute for ‘Greensphere’ that is both hardier to cold and a little easier to cultivate. Russet red berries that follow are a treat for the birds that get there first. Accepts the hottest aspects, drought, and brutal cold. Bienvenidos, Panchito!
Foliage Color: Dark Green
Arctostaphylos x densiflora ‘Howard McMinn’
A FANTASTIC Manzanita ‘Howard’ forms an extremely handsome evergreen shrub to 7’ tall and as wide in as many years. Striking mahogany bark is smooth with dark glossy deep green leaves. Profuse clusters of pink urn-shaped flowers appear in late winter and change to white over a period of six weeks. Maroon berries follow in summer. One of the most adaptable to landscapes, tolerates some summer irrigation but absolutely avoid boggy conditions and heat. A fantastic performer in our climate. Excellent as a specimen, basic landscaping shrub, or even informal hedge. Tip prune in summer to limit size and shape if required. Somewhat formal appearance year round. Very nice as an informal hedge and wonderfully adapted to steep slopes. Very good black spot resistance. Verdant and healthy year round. Adaptable to very HIGH overhead shade in woodlands. Avoid rich soils and do not improve. Best in un-amended native soils. Great formal looking shrub for rough conditions. Cold hardy to 5ºF. Exceptionally long lived in our climate.
Arctostaphylos x hookeri ‘White Lanterns’
Stellar small scale Manzanita that is a winner in gardens. Smaller leaves have a finer texture than most shrub types. Forms a symmetrical, dense dome to 3′ x 5′ in 5 years of medium green foliage. Massive bloom as clusters of white flowers (tinted pink in cold weather) occur from every branch tip in January to March. Very showy russet/mahogany bark. One of the best performers in our climate and scaled well for smaller gardens. Wonderful performance in Hell Strips, even large rock gardens. In time you may remove the lower tired branches that have become shaded out and reveal the smooth spectacular peeling trunks. Little to no summer water. Full sun to very light shade in well drained to average soil. Excellent cold hardiness as well as resistance to black spot. As with all give it good air circulation. Adaptable.
Arctostaphylos x media ‘Martha Ewan’
Our former employee Dan found Martha growing in the cemetery of the coastal town of Manzanita. It was bound to happen. This naturally occurring hybrid between Hairy Manzanita (Arctostaphylos columbiana) and the ground cover Kinnick Kinnick (Arctostaphylos uva ursi). Fantastic low growing evergreen shrub that is a superior ground cover. Dense growth clad in deep green leaves covers the ground on a 2′ x 6′ framework. White flowers in spring are followed by large red berries which are then consumed by wild life. Full sun to very light shade in most well drained soils. No summer water when established. Fast growing with little care. Amazing on slopes where it efficiently blocks weeds and the best ground cover Manzanita that we grow.. Better, easier, and faster ground cover than Arctostaphylos uva ursi- Kinnick Kinnick- dense growth is more vigorous and requires less maintenance or even supplemental water. Handsome and immensely easy plant. Though not technically a shade plant this variety can handle quite a bit of shade- avoid low dark shade, high overhead shade is best. Oregon native plant.
Xera Plants Introduction.
Artemisia douglasiana
Many learn this plant as Douglas Mugwort but its more official common name is Douglas Sagewort. This aromatic vigorous perennial is common throughout western Oregon. It happily inhabits everywhere from ditches to the headlands at the beach. The plant has medicinal qualities that were used by native Americans and they also used the pungent smoke to ward off the spirits of the dead. To 3′ tall and spreading underground by rhizomes. This is a very vigorous plant when established, give it room and the respect it requires. In improved situations it can swamp other plants so best to leave your patch of sagewort to its own devices. Mix with other plants of similar vigor- Spiraea x pyramidata or Rosa nutkana. Give it at least 5′ x 5′ feet to roam. In summer plumes of off-white flowers produce a haven for pollinators. This member of the daisy family brings them from long distances. Very long lived deciduous perennial with long indented leaves that are dark green on top with an underside of pure silver. This makes this almost woody perennial very easy to spot in breezy conditions It appreciates average soil and light water to establish.. If it flags in drought you may give it a deep drink in summer to refresh. Loved by a host of butterflies. Doesn’t need much love to perform. Oregon native plant.
Aruncus dioicus var. acuminatus
Goats Beard is a big bold and easy to grow perennial for part shade and perpetually wet sites. To 4′ tall and as wide with large fountains of pure white flowers in late spring to early summer. Native in seeps and along watercourses, mimic those conditions in your garden and you’ll have success. Long lived plant that develops a woody base. Completely winter deciduous. Excellent combined with other mesic water loving plants. Tolerates some inundation but not during the growing season. Often found on cliffs away from the browse of deer. Very large permanent perennial in time. Fall color is often yellow. Widespread in the PNW. Native in the Portland City limits. Oregon native plant.
Aspidistra elatior
Cast Iron Plant. Once you realize how incredibly useful and uniformly good looking this perennial of dry shade is- its as if there has been an awakening. Upright wide then tapered deep green evergreen foliage is famous for its ability to thrive in dust dry black shade. Well, its more adaptable than that. It makes a great evergreen texture, presence in any shady setting. It really does require protection from bright hot sun- it will discolor the leaves and recovery is a long slow process. To 2′ tall and forming a slowly spreading clump to several feet wide in a half dozen years. In summer brown, round flowers resemble pepperoni and appear at soil level. Curious. Well known as a houseplant its time to use it more in our gardens. Containers, sites in dense shade. Great winter appearance. To speed growth plant in enriched, well drained soil and water diligently during the heat of summer. Long lived plant.
Aucuba japonica ‘Hosoba Hashifu’
A dazzling female selection of Japanese Aucuba with long, thin, tapered leaves of deep green randomly splashed with yellow flecks. Dense and slow growing evergreen to 5′ x 5′ in 7 years. This selection will produce clusters of large red berries if a male is present. Very showy. Tiny brown/green flowers in spring are not conspicuous. Part shade to quite a bit of shade in average to enriched well drained soil. Established plants are incredibly drought tolerant and this striking shrub adds light and texture to dry shade areas. It will take full sun with regular irrigation and the leaves will be not as dark lustrous green. A very handsome shrub year round with great cold hardiness. Regular water through the first season to establish. Then light water. Long lived, easy to grow shrub whose dense habit does not require pruning.
Aucuba japonica ‘Longifolia’
Tough and useful evergreen that is always at its shiny green best. Large growing for an Aucuba exceeding 6′ tall and as wide in 7 years. Moderate growth rate. Long glossy green leaves are slightly serrated and very pretty. Endures the deepest, densest dry shade conditions with no issues. Adaptable to full sun but not reflected heat. Tiny brown flowers are not conspicuous but this is a male and makes a great pollinator for female Aucuba (see A. ‘Rozannie). Established shrubs can get by with little to no summer water and not suffer. Pretty foliage shape is a great medium for contrast. Plant with Japanese Forest Grass or Dicentra formosa ‘Langtrees’. Incredibly cold tolerant- slightly below 0ºF. A good candidate for windy, cold gardens.
Aucuba japonica ‘Rozannie’
Rosanna Rosanna Danna is what I think of when I see this cute tough and useful shrub. I have no explanation, I just do. Slow growing broadleaved evergreen with deep forest green leaves that are glossy and pretty at all times. A female that is pretty much self fertile- My kind of woman, yeah 2018. Small green/brown flowers make themselves into glossy red berries. Bring a man around and the crop multiplies. Best in part shade in rich, well drained soil with light summer water. In reality once established Rozannie can go all summer and not miss a drink. To 3′ x 3′ and dense. Avoid blasting hot exposures which will yellow the leaves and rob the whole plant of luster. Supremely adapted to dry shade. Super cold hardy to quite a bit below 0ºF without any tragedy. Japan.
