Achillea millefolium 'Pretty Woman'

Achillea millefolium ‘Pretty Woman’

Of all the selections of our native yarrow this stands out for many reasons. The ‘umbels’ of flowers are a rich red which holds the color for an extended period. It fades only slightly to a rust red with time. Its vigorous and easy to grow. And it re-blooms reliably if spent flowers are removed. All the way until frost and sometimes longer. A very, very good long-lasting cut flower. To 18″ tall forming spreading colonies. Semi-evergreen. Low water when established in well-drained soils. Excellent to moderate deer resistance. Appreciates an annual application of compost.  Oregon native plant.

Achillea millefolium ‘Salmon Beauty’

Achillea millefolium ‘Salmon Beauty’

Yarrow is an unbeatable native perennial that blooms for a LONG time with a minimum amount of effort from the gardener. Foamy, ferny gray green leaves creates a low carpet of evergreen foliage. Rising up on 2′ spikes flat umbels of soft salmon flower create landing pads for pollinators. The flowers fade lightly after opening for a wonderful multicolor effect. Remove spent flowers, apply a little water and it will repeat bloom until frost. Best in lighter soils that are enriched but drain quickly. Best floral displays occur with light consistent summer water though it is very drought tolerant when established. Tolerates the toughest, hottest sites. Admirable if a little pungent cut flower. LOVED by pollinators. Creates a growing patch to several feet wide quickly. Blooms spring- autumn. Moderately deer resistant. Borders, dry borders, hell strips, etc. Oregon native plant.

Achillea millefolium ‘Willamette Gray’

Greg got seed of this distinctive form of Yarrow near Oregon City. Unlike most garden varieties that are derived from European stock which very much appreciates rich soil and regular water to perform and those forms are also not pungent. We wanted our locally native yarrow that is incredibly durable, has gray foliage that is pleasantly aromatic with broad white flowers. This is a much more climate adapted perennial. Its found throughout all of the state, and can be found anywhere from meadows to surprisingly deep woods. This is a very thrifty plant and once established it really doesn’t need supplemental summer water. Spreads to form finely divided low gray foliage. The flat umbels of pure white flowers are very large and this is a landing pad for all pollinators as well as butterflies. To 20″ tall in bloom. Excellent meadow component with clumping grasses, annuals, and bulbs. A great plant for hell strips and hot aspects too. Very easy and forgiving perennial. Blooms May-August. Mostly evergreen save for the very harshest winters. Not bothered by deer.  Oregon native plant.

Achillea sibirica

Achillea sibirica

A wonderful relatively new Achillea (Yarrow) from Siberia. It brings not only larger chalk pink flowers in bold umbels it is cold hardy to USDA Zone 2. This plant will never freeze out.  Forms expanding clumps with upright stems clothed in glossy long green leaves with small teeth. On 22″ stems umbels of flowers appear from May to August. After the first flush of flowers shear away and water and another round will commence. The long stems make great long lasting cut flowers too. Loved by a bazillion pollinators, hover flies, bees of all kinds swarm the flat landing pad. Full sun to very light shade in rich, soil that drains. Incorporate some oxygen in by double digging. Good companion plants are Agastaches and Penstemons as well as ornamental grasses. Completely deciduous in winter. Light consistent summer H20 to establish. Long lived perennial. Moderate deer resistance. Elegant perennial. Siberian Yarrow.

Acorus calamus 'Variegata'

Acorus calamus ‘Variegata’

Nifty foliage perennial that can double as a terrestrial border plant (with regular water in rich, moisture-retentive soil) or submerged as a border perennial in a water pot or the edge of the pond. The majority of the spikey 3′ tall leaves are composed of cream/ivory streaks with dramatic stripes of deep green. The effect is ghostly and vivid from quite a distance away. Forms large spreading clumps in time. To 4′ wide when things are going well. Full sun to part shade. Flowers are not very conspicuous spikes that hide within the foliage. Completely winter deciduous- this is nice, it makes cleaning up in late winter/spring easy and and no fuss and the plant begins anew and fresh each season. Not bothered by pests. If sunk in a pond or water pot use heavy clay soil- like from the ground and mulch with a layer of gravel. Long lived plant. High deer resistance. AKA. Ghost Sweet Flag.

Acorus gramineus ‘Golden Lion’

Is this the best form of golden sweet flag or what? We love the vivid yellow leaves on a dense and arching evergold perennial. Clumps densely but the foliage is born in fans and spreads out. To only 6″ tall but spreading to 1′ wide. Best in part shade and either permanently wet sites or regular consistent water. Mine makes a happy home on the north side of my house at the base of the rain gutter. Plenty of water in winter- and I don’t forget to water it in summer. Good appearance year round. In spring little off-white spikes serve as flowers. Native to permanently wet sites. Give it a bit of shade. Moderately deer resistant.

Its even locally native from Maryland to New Foundland. Its a long lived and vigorous fully deciduous perennial for perpetually wet sites. To 2′ tall and spreading almost indefinitely where conditions suite it. Heavy clay soil that retains consistent moisture in part shade to shade.

Adiantum venustum

Adiantum venustum

Himalayan Maidenhair fern is one of our favorite groundcovers for shade and rich, moist soil. The divided fronds in the shape of an arrow are always soft and fresh. In spring this deciduous variety emerges with tones of amber and soft pink before taking on a mature soft green hue. These delicate leaflets are held on thin, wiry black stems to 10″ tall and it spreads prodigiously to form vast colonies. It doesn’t smother neighboring plants however, instead it seems to just flow around such woodland neighbors as Epimedium, Hellebores, even woodland bulbs like Erythronium. Regular summer water. Avoid hard, compacted dry soils. High deer resistance.

Agapanthus ‘Bee Bop’

I selected this seedling about 8 years ago and its been growing in my garden for all that time. A completely deciduous variety that does not show leaves until all chance of frost has passed. Forms a large clump with strappy arching green leaves – to 2′ across in 5 years. As the clump increases so do the amount of flower stalks. The orbs of flowers are neon to cobalt blue. An arresting, glowing blue. Slightly smaller in diameter than other varieties (about the size of a baseball) this plant packs a LOT of flowers onto a stalk- at least 50 and they reverberate above the clump for weeks in July to August. To 26″ in bloom. The stalks that support the vivid flowers are incredibly strong and they barely bend in a breeze. This is a wonderful perennial for full sun and rich, amended soil. Add a handful of lime at planting time to ensure neutral pH. Disappears cleanly in winter. Regular water though its bloom cycle. Pair with chartreuse foliage for a dynamic contrast. Loved by hummingbirds and bees. Best in the center of an ascending border from low plants to tall. Long lived, cold hardy selection that we love.

This is a very handsome and dependable hardy Agapanthus bred in Ireland.  It forms a spreading clump and in mid summer 3′ tall stems support multiple pendant midnight blue flowers.. Full sun and rich soil. Add a handful of lime to the planting hole. Our soils are acidic and this perennial likes neutral (7) Alkaline (sweet) soils to perform at its best. You can also plant it next to a concrete sidewalk which will also give it the alkalinity that is craves. The clump of scrappy mid green leaves is shorter than most varieties and maintains a tidy plant both before and AFTER bloom so it makes an exemplary garden and landscape perennial. Regular water is crucial through the bloom period, July /August when flowering ends and you cut away the dead stalks it remains good looking until it totally disappears in mid autumn. Irish and UK Agapanthus appear to have much greater cold tolerance than American selections,  they wait to emerge until all threat of a freeze has passed. Very cold hardy easy to grow wonderful pendant tower of cobalt blue. The truss of flowers is very large and showy. Good cut flower, loved by pollinators too. Limited quantities. One of the finest lily of the niles for our gardens.
