Arctostaphylos x densiflora ‘Howard McMinn’ flowers

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'

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.

Arctostaphylos x media 'Xera Pacific'

Arctostaphylos x media ‘Xera Pacific’

Our discovery of a naturally occurring hybrid Manzanita on the Oregon Coast. Low and spreading to 2′ tall and 5′ wide in 5 years. Light green paddle shaped leaves. White urn shaped flowers in spring. Bark exfoliates to mahogany and shredding with time. First rate dense weed smothering groudcover. Black spot resisitant. Full sun to part shade in average, well drained soil. No summer water- though it tolerates it better than most. Great Oregon native shrub. Cold hardy. Russet/red berries follow the flowers and are consumed by wildlife. Very similar in habit and use as ‘Martha Ewan’, they are almost interchangeable. The foliage is more rounded and lighter green than the previous. Oregon native plant.

Erica arborea 'Albert's Gold'

Erica arborea ‘Albert’s Gold’

Very cool selection of Tree Heath that has exciting acid green/chartreuse foliage- brighter when new and masses of white flowers that smother the foliage in spring. Tough evergreen shrub for full sun and very little summer water when established. To 5′ tall and 4′ wide in 7 years for rich to average well drained soil in full sun with good air circulation. Spent flowers remain on the shrub and morph to a rust color with time- giving the whole shrub a rusty/chartreuse combination of colors. Not for formal gardens. This member of the mediterranean garrigue is drought adapted and cold hardy. Moderately fast growing. Showy in spring bloom.

Erica cinerea 'Velvet Night'

Erica cinerea ‘Velvet Night’

Heathers and Heaths are fun to grow, but the tales of failure are epic. The easiest Heaths are Ericas and they all like some sort of regular summer water to thrive, bloom and adapt. This is a favorite shrub aside from being the darkest flowered Heath that we’ve seen. Beginning in June with a summer crescendo that bleeds into autumn with deep beetroot purple flowers on deep black green needle like foliage. To 2′ x 2′ in 3 years and fairly upright for an Erica cinerea. Outstanding long season of summer bloom that is a thrill to hummingbirds as well. Great aesthetic and cultural companion for Grevilleas. This Heath will bloom while most Grevilleas are having a summer bloom rest. Shear after blooming (fall) this will increase density as well as blooming wood. Full sun and rich to regular soil with regular irrigation for the first 3 years- then much less. This is a dark shadow of a shrub. We love it. Moderate deer resistance. Mulch heavily with bark after planting and annually. The secret to Heaths and Heathers in our climate is mulch, mulch, mulch. Excellent performance at the coast.

Erica mammosa 'Orange'

Erica mammosa ‘Orange’

This is a tender Erica inland. It prefers the Oregon coast (Zone 9) and it performs there wonderfully. A large growing S.African heath that displays copious large tubular orange flowers from Aug-Nov. Excellent potted plant if you protect it from temperatures below 20ºF. Move to an unheated garage or bright cool room during times of arctic air. To 3′ x 3′ and mounding. Cut flowering stems last quite a while in water. Full sun and rich, to average soil that drains. Regular summer water. Not a particularly fussy plant. Takes coastal conditions like a champ. Spectacular in bloom. Moderate deer resistance. South Africa.

Erica terminalis

Erica terminalis

Tree heathers fascinate us and this widespread species of southern to northwestern Europe makes a fantastic, drought adapted garden plant. Fine needle like green foliage lines strongly vertical growth. In mid summer the tips of the stems produce many urn shaped pale pink blossoms that are showy for up to 6 weeks. Following the bloom period these remain on the shrub and turn a russet color adding to its charm. To 3′ x 3′ in 4 years. Full sun and well drained average soil with light summer water to establish. Once you have it going it requires no supplemental water. Great for dry areas, gravel borders, hellstrips. Excellent fine textured shrub that develops a shredded gnarled brown trunk with time. Moderate deer resistance. Gains drought adaptation with age. As with most ericaceous plants it must build up a large root system over time and then it is drought adapted and will sail through the driest summers without fainting.

Gaultheria shallon

Salal. An iconic native shrub that occupies the understory of the forests from the coast to the Cascades- in the Willamette Valley its restricted to the shadiest, mesic environs. A mounding evergreen that forms large colonies in time. Ranges in height from 2′ to 6′ depending upon its situation. Spread is indefinite when happy. In spring chains of white urn shaped flowers transform into edible berries. Very handsome foliage is used as long lasting cut material and is sometimes marketed as ‘lemon leaf’.  Can be tricky to establish. Shade to part shade is best in rich, humus rich soil with regular water. To establish water, water, water. And apply a liberal deep mulch.  Avoid hot sun and compacted dry soils. Once it gets going, its yours forever. Occurs naturally in mesic/shady environs around Portland.  Mulch annually to accumulate a layer of organic material that this spreading shrub craves. Oregon native plant.

This is a very pretty and very useful plant that is tough as nails when established.  To just 3′ tall by as wide in 10 years.  In late winter the whole shrub is a garland of white urn shaped flowers on fine filaments. Bloom begins in February and remains effective for months. Medium green evergreen foliage with great year round appearance. Fits in small places  in full sun to quite a bit of shade. Regular water to establish then light water to eventually none on well established shrubs. Rich soil with high organice/wood content that is acidic. Very easy to grow in our climate and one of the best Pieris. Flowers buds are set the previous summer and are attractive for months until they open. New growth is tinted red. Very cold hardy enduring subfreezing wind and temperatures below 0ºF. Not bothered by deer- for the most part. Wonderful small hedge or specimen. Long lived.
