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.
Plant Type: Herbaceous perennial
Perennials are the organic heart of the garden. They return year after year and represent the most sustainable type of gardening. We offer varieties that are difficult to find, that are extraordinary in performance. Evergreen perennials make up a large component in our climate where snow is limited and landscapes are green. They maintain a continuity through the darkest days of the year. Many of our perennials are drought adapted when established and combine well with drought adapted shrubs. We are constantly expanding our offering of native perennials- a category sorely lacking in our gardens.
Native perennials have specific requirements
Just because a plant is native does not automatically mean that it is easy to grow in a garden. In fact, adaptation to summer drought means that you are in greater danger of overwatering than under watering. Many native perennials are slow to finish to sale size. Adelina, Wyethia, are two examples of highly sought native perennials. Turns out it takes about 3 years for them to bulk up to a size that we feel confident will survive when sold and planted out. Conversely, there are many native plants that are easy to grow in container culture but they have a rough transition and low transplant survival rate- most often they are adapted to specific edaphic conditions (soil conditions) and those must be replicated in the garden as close as possible.
Extra care for natives, protection from invasive plants
Finally, the biggest threat to native perennials is being swamped by invasive non-native grasses and weeds. You can’t just randomly plant them out and expect them to adapt immediately. Treat them as well as you would any perennial. Add a touch of all organic fertilizer to the planting hole and definitely mulch and make very sure to protect them from invasive plants. Non-natives are adapted to horrible, compacted soil of all types- they are survivors that are adapted to win. Plant densely and by all means, MULCH and care for your native plants they require our assistance.
Climate Adapted Plants for Gardeners in the PNW
Big in every way this Golden Rod of the west rises on sturdy semi-woody stems to display a chalice of fragrant gold flowers. Better put in latin the broad flowers are pyramidal paniculiform arrays, That about says it. Large growing perennial that is found in specific wetland sites around the state (and the west). It spreads laterally by strong rhizomes with stems that rise to 4′ tall. The PYRAMIDAL PANICULIFORM gold flowers emit a sweet pollen fragrance. This and the fact that it is in the daisy family draws a broad amount of pollinators from far and wide. It dies down in winter and the previous years stems can be taken away then. Give it at least 5′ x 5′ to roam. Water to establish then a light consistent water in summer for best flowering. Full hot sun not tolerant of shade at all. A large, regal cut flowers for big displays July-September. This form was found in the Columbia River Gorge near the river. It can also be found around wetlands in arid parts of the state as well as river courses along the west side. The underside of the stems flashes silver with green on top. These incredibly sturdy vertical stems will never topple. Mix with Hall and Douglas Asters for similar space, bloom time and vigor and you’ll quadruple your pollinators. Oregon native plant.
Solierolia soleirolii
Baby’s Tears is a useful and surprisingly hardy small scale ground cover. Famous for its role in terrariums its surprisingly hardy to cold as well. Tiny leaves overlap in a perfectly flat deep green ground cover. Part shade to shade but not terrible dry shade or compacted soils. Spreads to several feet wide in several seasons. Rich, moisture retentive soil that drains is ideal. Mist or water once a week to increase humidity which it very much appreciates. Freezes to nothing below 15ºF- resprouts from bits of root vigorously in spring. Do not try to cover the whole planet with this diminuitive plant. Instead isolate it to cool pools of green several feet wide. Excellent in containers or as an easy houseplant.
Sphaeralcea ‘Hot Pink’
Globe Mallow. Fun and easy to grow perennial that behaves like a sub-shrub. Semi woody wands of very silvery small maple shaped leaves wave to 3′ tall. Lining these silver stems are bowl shaped hot pink flowers. They begin as early as late May and continue unabated for months. As time goes on this perennial for dry, hot locations with good drainage becomes a showy hot pink mass of blooms. Excellent on hot slopes with light but consistent summer water. Very drought adapted but light water appears to improve the performance. Loved by bees, butterflies and other pollinators. By autumn this 3′ x 3′ shrub should be left intact to over winter. In spring when new growth is breaking from the base it may be cut back hard and recovery to bloom is rapid with the onset of warmer weather. Cold hardier if given very good drainage. As far as I can surmise it will take temperatures down to about 10ºF. A selection or possible hybrid from two southwestern globe mallows.
Sphaeralcea ‘Newleaze Coral’
An American western native wildflower that was selected for its unique flower color in the UK. Well, welcome home my pretty globe mallow. A tall growing semi-woody perennial with soft gray/green foliage. From June to September and longer cupped vivid coral flowers line the 3′ stems. It blooms non-stop for up to two months. Very pretty. Full, hot sun and rich, to average WELL DRAINED soil. A natural for a slope or included in a border where you water just on occasion. Very drought adapted for full hot sun. Do not cut this big wavy perennial back in autumn- leave the top growth as added winter protection. Cut back by 2/3 when you see new growth pushing in spring. Good drainage is key for the combination of wet + arctic air. Dry its hardy way below 0ºF- moist- well, a lot warmer. Excellent long blooming tall plant for seasonal containers as well. Does not like shade. Don’t even try. To 2′ wide.
Sphaeralcea incana
We’ve been impressed with the performance of this striking very upright globe mallow. Spikes clad in soft orange flowers appear continuously for months in summer. To 4′ tall ultimately this forms a semi-woody clump to 2′ wide. Full, HOT sun and WELL DRAINED soil with light summer water. Freezes back in winter almost to the ground and vigorously resprouts for the base and grows quickly when hot weather arrives. Excellent on slopes, hot gravel gardens. Not bothered by rust or other diseases that can afflict mallows. Mulch lightly for the first winter for added protection. Stunning in bloom and carefree once established. Cut back dead top growth in mid-spring. Some deer resistance. Takes blasting reflected heat well. SW native plant.
Stachys coccinea ‘Coral’
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.
Stachys lavandulifolia
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.
Stipa barbata
Silver Feather Grass- our favorite ornamental grass. From humble blue leaves that form an upright grassy clump stems rise to 4′. As the flower open they unfurl- curling 18″ long horizontally and covered in soft downy hairs. The slightest wind puts these streamers into graceful motion. Blooms June-July. When the flowers ripen and begin to detach they can be gathered and made into a bouquet and the tails will curl up and form a soft tan haze. An arrangement lasts forever. Often self sows in open conditions- and this is good because it is not an easy grass to germinate and does not work from division. Easy to move when small. Give it an open position where you can observe the streaming flowers unobstructed. Very hardy and little summer water once established. Full sun. Semi-evergreen foliage in winter. High deer resistance. Spectacular grass. See video below.
Stipa gigantea
This is the giant straight species that is so popular for its soaring silver stems and golden drooping awns. To 12′ tall in bloom from a tight but large basal clump of fine deep green leaves. Perfectly evergreen with a great winter appearance. Very easy to grow grass that provides spectacular garden effects. Incredibly drought tolerant in any well drained soil- including clay if it is not allowed to become bone dry concrete. Flowers make a great see through “scrim” in gardens. Fun to grow. Moderate deer resistance. Site where you want a see through hedge or texture that towers above you. Very cold hardy. Native to countries adjacent to the mediterranean. See video below IMG. 6620.
