Plant Type: Shrub

Shrubs are the backbone of Pacific Northwest Gardens. We’re able to grow an incredible amount from all over the world. From evergreen to deciduous the choices are vast. We focus on mostly (but not all) low water species and many native western species. Shrubs are often much less thirsty than other plants and live for a long time if properly sited. They can sport amazing foliage or scintillating flowers.  From Manzanita to Ceanothus and even Grevilleas nothing makes a garden look more western. Our choice of shrubs is from years of experience growing them in our own gardens.

Climate Adapted Plants for Gardeners in the PNW

 

Arctostaphylos columbiana ‘Parkdale East’

This form of our native Hairy Manzanita was found quite far east of the Cascade crest and offers greater hardiness to cold. Unfortunately, it has the same characteristics of the species- it is unpredictable. To 4′ x 7′ with sage gray leaves and white to pink-tinted flowers in spring. Very well-drained soils in an open position with NO summer water when established. Dramatic smooth mahogany bark is an outstanding feature. This is the variety that is best suited to life in the Columbia River Gorge and possibly eastern Oregon. Best with total neglect and full sun. Russet berries follow the flowers into summer and autumn- always consumed by wildlife. Very limited quantities.   Oregon native plant.

Arctostaphylos columbiana ‘Wolf Creek’

Our native Hairy Manzanita is one of the most widespread species in the PNW. Unfortunately, its not the most reliable and can be kind of hard to grow. It will grow happily for years and then suddenly decline. No explanation. Large-growing shrub with gray green leaves, the telltale hairy leaf petioles and white flowers in spring. Russet berries follow. Its best attribute is the smooth exfoliating mahogany bark. To 8′ x 8′ very quickly in average, well-drained soil. No summer water. Great air circulation and little intervention from the gardener. Wild areas, dry hillside. This form we selected from the southern Willamette Valley. Oregon native plant.

Arctostaphylos hookeri ‘Wayside’

At the North Willamette Experimental Station in Wilsonville this special ground cover Manzanita has been consistently one of the best performers. Deep green pointed leaves are held perpendicular to the sun on cinnamon red stems. In time it forms glossy red bark that is very showy. Low and dense growing to 2′ tall and 6′ wide. Excellent bank cover or ground cover in any soil that is not amended or boggy. Profuse white flowers in spring. First rate weed suppressing plant for hellstrips, rock gardens, dry borders. Excellent appearance year round. No summer water.

Arctostaphylos 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. Massive flower 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. Great scale for Hell Strips, even large rock gardens. 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 manzanita ‘St. Helena’

A tree type manzanita that has been a stellar performer in our gardens. Rapid growth to 10′ x 10′ in 8 years. Broad, rounded sage green foliage is held perpendicular to the cinnamon red stems to avoid moisture loss (no flat leaves baking in the sun). In winter to early spring, clusters of white flowers are effective and visited heavily by pollinators. Russet red berries follow but do not last long because of animal predation. Open habit with time that exposes the muscular, smooth mahogany trunks. (Its thought the bark exfoliates to deter moss and lichen growth). This is a very hardy drought adapted west coast native shrub to small tree for average, well drained soils and NO summer irrigation. Full sun and room to spread. Avoid rich, amended soils- leaner conditions produce a much hardier and longer-lived plant.

Arctostaphylos nummularia ‘Select Form’

Stunning glossy perfectly round leaves line wiry stems on this dense, mounding, very happy low-growing Manzanita. New growth is tinted red and settles to bright green. To 2′ tall and 4′ wide creating a dense weed-suppressing dome of foliage. White flowers in spring. Very garden tolerant for full sun to very light shade. Moderately fast growing. Excellent candidate for hellstrips, hillsides, etc. Great performance at the Oregon Coast. Little to no summer water once established. Very very good looking plant. Easy to grow. Cold hardy to 5ºF.

Arctostaphylos pajaroensis ‘Lester Roundtree’

Virtually the same as ‘Warren Roberts’ it is completely interchangeable with that cultivar. Why do we grow ‘Lester’? Aside from having amazing blue foliage and clusters of deep pink flowers from January to March we LOVE Lester Roundtree. She was an amazing, intrepid self-taught botanist who roamed California in the 1930’s in her simple pickup truck camping and botanizing throughout that state. Her seminal book ‘Flowering Shrubs of California’ is a must read for any gardener on the west coast. And its not just about plants- Check it out. This shrub is large in time to about 4′ tall by 8′ wide. The pink flowers born on the blue foliage is a sublime combination. Following bloom new spring growth is a fantastic red/ orange before settling to blue. Bark is a smooth mahogany with time and the trunks are sinuous and winding. This is an excellent shrub in our climate. Once established it requires absolutely no supplemental water- ever. Sailing through temps in the 100’s and bone dry with NO visible signs of stress. Our kind of shrub. It is cold hardy and completely climate adapted. Hell strips, dry borders, informal shrubberies. Mix with Ceanothus, Grevilleas, Halimiums. Very pretty year round.

Arctostaphylos pajaroensis ‘Myrtle Wolf’

Not often seen in gardens this excellent winter blooming Manzanita has been a fantastic performer in PNW gardens. Upright growing shrub with blue foliage- new growth is dramatically tinted red. In January to March copious bright pink clusters of urn shaped flowers appear. Anna’s hummingbirds are not far behind. To  5′ x 5′ in 6 years in full sun and average, well drained soil. No summer water when established. Excellent winter blooming shrub that is always good looking.

Arctostaphylos pajaroensis ‘Warren Roberts’

Big beautiful Manzanita that has thrived at our very cold wholesale nursery for almost 20 years and has never been harmed by weather. To 4′ tall and up to 8′ wide the new growth emerges a fiery orange red before settling down to a nice gray/blue. In late winter pink tinted urn shaped flowers decorate the whole shrub. The combination of the blue foliage and strongly pink flowers is magical in winter.  Well drained average to poor soil in full sun is ideal but it can get by with less than ideal conditions. Water to establish the first summer then none in subsequent years. Give Warren room- he’s greedy.

Arctostaphylos pumila ‘Small Leaf Form’

Immensely handsome dense rounded Manzanita that has smaller than average silver foliage and fantastic bark.  Moderately fast  growing shrub to 6′ tall x 8′ wide in 8 years. In late winter each branch tip is bedecked in clusters of small white flowers- they are born in profusion and expand from pink buds. Russet colored berries often follow and are consumed by wildlife. The black/mahogany glossy bark is beyond striking with the silver foliage. It splits, rolls up into ribbons, and exfoliates in late summer. In time it may be pruned to reveal trunks–for most of its youth they are hidden by dense almost formal looking foliage. Adaptable to many soils including clay soils- especially on slopes. Excellent long term landscape plant that looks great year round. Very good cold hardiness enduring 0ºF with no problem. Dig a hole 3x as big as the rootball in the pot to loosen the soil and allow the new roots to penetrate virgin soil. Water regularly through the first summer- then little to none in subsequent years. Combine with green leaved Arctos for great foliage contrast. Perfect on slopes, areas with intense reflected heat such as parking lot planter islands. Great urban shrub. Appreciates good air circulation.
