Compact and very flowery this form of the dependable Abelia fits into smaller areas and perfumes the late summer to autumn gardens with masses of small white flowers. To just 4′ x 4′ in 7 years for full sun to light shade and most soils. Drought adapted when established, it will also accept regular summer irrigation. Slow growing and cold hardy evergreen. Following the massive bloom, the calyx of each flower remains and turns madder red. A second season of showiness that persists as a red glow through winter. This dense shrub retains its good looks for year without needing much pruning. Pruning should be done in early spring. Blooms on wood from the current season.
Improved selection of the Chinese Lantern Plant- which is actually from South America, and this form has larger more flared yellow petals. They extend and recurve from the bold red calyx. This arching multi-stemmed shrub blooms almost non-stop from June to frost and often longer. Vigorous to 6′ tall and 4′ wide forming a large patch in time. The arching thin stems and skinny pointed leaves display the rows of flowers perfectly. A hummingbird delight. One of the hardiest to cold this behaves as a sub-shrub in the coldest winters- freezing back but returning boldly from the ground when the soil warms. Most winters, damage is restricted to burned tips and the majority of leaves which will drop. Plant with the base in a protected location- for instance between low shrubs to protect the crown, or near the base of a wall. Mulch if arctic (below 20ºF) weather threatens. Following a freeze the plant will look absolutely awful. Refrain from cutting it back until you see new growth emerge- either from the base or vertical stems. In any case water it consistently and heavily until you see vigorous new growth- the transformation with regular water is remarkable. So, don’t by any means give it up for dead. Full sun to quite a bit of shade. A bit tall and lanky for containers- just plan for this. Rich, WELL DRAINED soil improves both cold hardiness and speeds recovery. Excellent performance at the Oregon Coast.
An exciting shrub/small tree with paddle shaped blue evergreen phyllodes for foliage and in late winter to early spring a massive display of luminous yellow flowers. I’ve always loved Australian wattles so it was with great excitement that we decided to grow this striking plant. Moderately fast growing to 16′ tall and 8′ wide forming either multiple or a single trunk. The bark is chocolate brown and smooth. Very few Australian Acacias will thrive in Portland, its just about 5 degrees too cold in our coldest years. This one is different, (a few species will live for 4-6 years before they finally succumb to Jack Frost. Acacia pravissima etc.) This, however, is the cold hardiest that we have grown. It is hardy to just below 10ºF for brief stints- good enough for long term survival. This is a rare limited endemic to the high mountains of New South Wales but is popular as a garden subject the world over. The small, fluffy, balls of electric yellow flowers foam among the blue leaves – incredibly pretty. Full sun and a protected location – against a south facing wall is ideal for a very pretty fun to grow tree. Once fully open the flowering stems may be cut for long lasting bouquets. Blooms on wood from the previous season, prune if needed after flowering has ended. Light consistent water to establish . Not fussy about soils and happiest in full, all day sun. Protect from subfreezing east wind. Bloom time is concurrent with several earlier Ceanothus (‘Blue Jeans’, ‘Dark Star’, ‘Concha’) and creates a vivid early spring yellow and blue display not soon to be forgotten. Drought adapted when established. Not bothered by deer/elk- not entirely sure about rabbits- if they are profuse in your neighborhood it wouldn’t hurt to protect the plant with chicken wire when young. Beautiful year round and spectacular in bloom. AKA Blue Bush.
Outrageous Bear’s Breeches for hot and sunny aspects. Forms large rosettes of spiked intricate leaves that almost lay flat on the ground. In summer, enormous chalice-like soft purple blooms rise to 2′ tall. Each flower opens to reveal yellow petals. A beautiful combination. Full sun and rich, well drained soil with light summer water. Give this plant room and air circulation. It does not like to be crowded. Fully cold hardy and completely winter deciduous. Established plants can get by on less water. Moderate deer resistance. To 2′ wide in several seasons. Spectacular cut flower.
This is the locally native form of our wild yarrow. A rambunctious, easy to grow evergreen perennial for rough sites in well drained soil in full sun. Continuously from spring to autumn ‘umbels’ of pure white flowers rise 18″ above low spreading aromatic, finely divided ferny foliage. Most often it is green with variants that have gray foliage from time to time. Low water perennial that can even be used as a lawn substitute. A single plant spreads to several feet wide. Moderate deer resistance. Butterflies oh the butterflies.This is a pioneer perennial and will often out compete less robust native perennials. Its best use is as a contained weed. It is great for pollinators Individual plants rarely persist more than 3 years. Oregon native plant.
A fine form of our native Yarrow that has leaves that are a striking gray with pure, clean white flowers. A great combination. Spreads to form a low wide plant that is evergreen (gray). The flat clusters of flowers appear continuously from May to frost. More consistently if you remove spent flowers. The umbels, unusual for the daisy family, are loved by butterflies. Well, actually all pollinators. They are given a flat landing pad and tons of flowers- what more could you want. Excellent for low care areas where this romping perennial will happily out compete weeds and hold ground with very light amounts of water. Full sun and well drained soil. its best to double dig the soil to incorporate oxygen and de-compact the soil. Does not like compacted soil. Light but consistent summer water speeds growth and vigor. Otherwise very drought tolerant. Excellent on slopes. To 20″ tall in bloom on a low spreading foliage plant to 2′ wide or wider. High deer resistance. Great cut flower. Mix with other low water plants. Pretty with other colors of yarrow. Oregon native plant.
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.
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.
Sweet little evergreen shrublet with fine blue foliage. Atop a rounded form in spring, masses of light pink flowers are incredibly showy for such a diminutive plant. To about 8″ x 1′ forming a bun. This member of the brassica tribe is excellent in rock gardens or even on hot dry sunny slopes. Full sun and average, well drained soil. Light to little summer water. Blooms for 3-4 weeks in mid to late spring. Cut back hard after blooming- new blue foliage will flush out almost immediately. Troughs, rock gardens. Low care rock garden classic.
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.
