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.
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.
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.
Western Maiden Hair Fern is native from the Aleutian Islands in Alaska south mainly through shady wet spots in the west south as far as Chiahuahua, Mexico. 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. Often found lining water falls in Oregon or in deep cool moist gullies. The multi fingered leaves are a soft green and are held erect on jet black stems. Very good sited at the bottom of a downspout. Very easy to grow given consistent moisture. Oregon native plant.
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.
Cool hybrid between two California native maidenhair ferns that we love because its EVERGREEN! Finely divided soft green leaflets surprise as they sail through the toughest winter with little or no damage. A clumping variety that slowly increases over time in rich, moisture-retentive soil in part shade to shade. Adores moisture but can go much drier than most maidenhairs. To 10″ tall and as wide – then increasing. Lovely thing that works in woodlands to containers. Excellent naturally-occurring hybrid that deserves a place in our gardens. Moderate deer resistance.
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 strain of Agapanthus from the very cold hardiest varieties that we grow. Not only are these perfectly hardy to cold they are naturally completely deciduous. Even better they wait to emerge until all danger of frost has past. Many ‘hardy’ CA varieties leaf out in the false spring of late winter and then get nipped hard by possible late freezes. Not at all fussy about soil but best in enriched soil with light consistent summer irrigation. Large globes of rich sky blue flowers are bigger than a grapefruit and wave at the top of 3′-4′ stems. Quite a bit taller than other hardy varieties. Full sun to very light shade and not fussy. They will live in containers for eons and bloom like crazy. Flowers appear from late June to early August and are very showy. This is a very pretty tall strain that is reliable and kind of hard to F up. If you’ve lost Agapanthus in a cold garden or unfortunate freeze this is the one to try. As with all Agapanthus they thrive and bloom in neutral to alkaline soil. Incorporate a handful of lime in the hole at planting time. Strappy clumps of mid-green leaves are handsome following bloom. As the plant multiplies it increases its blooms stem count markedly.

Born and bred in the PNW this excellent compact and extremely floriferous white flowered Lily-of-the-Nile is a first rate selection. To 20″ tall and forming an expanding but compact clump. Flowers appear for 4-6 weeks in mid-summer. Clear, pristine white with abundant flower spikes- a small amount of leaves supports copious flower spikes- a great attribute of the best Agapanthus. Lots of flowers/few leaves. Full sun to very light shade in rich, well drained soil with regular summer water. Completely winter deciduous. Handsome pale green matte foliage. Long lived perennial. Mix with Blue Agapanthus for contrast. Bloom stems increase markedly with the size of the clump. Our favorite hardy white Lily of the Nile. Agapanthus do best in neutral to alkaline soil. Incorporate a handful of lime in the planting hole.
Our own seed strain taken from the very darkest blue flowers in the Agapanthus kingdom. Prolific blooming, long lived, cold hardy perennials that require rich, well drained soil with regular summer water. Full sun to very light shade. Blooms of the deepest cobalt to black rise on average to 30″ tall for 4-6 weeks in mid-summer. Completely deciduous in winter. Wonderful in the middle/back of a border and a natural with ornamental grasses and Kniphofias. Add a handful of lime to the hole at planting time and put the Agapanthus right on top of it. The parents of this strain are all naturally very hardy and do not emerge until all threat of frost has past. Hummingbird plant.
