A very pretty intergeneric hybrid tree between Catalpa and Chilopsis (Desert Willow). We really like this small tree that forms an umbrella shaped crown in time. To 20′ tall and continuously producing opulent large white flower clusters- the interior of the flower is marked with purple veining- much like an exotic orchid. The flowers appear on new growth and are continuous from June to September. The long thin tapered light green leaves have a nice texture. They do not color up appreciably in fall- making due with light yellow to off green before abandoning the tree. Excellent garden tree. We prefer the white flowered form as the often planted pink variety …..well, lets just say Portland has a LOT of pink flowering trees. Fast growing in youth-especially if well watered in summer. Otherwise, supremely tolerant of drought as well as rough, hot urban conditions. Casts moderate shade in time. Breaks dormancy late- usually late April. Be patient.
Interesting hybrid between two Mexican Oranges and wow, you get an incredible shrub that adores this climate. Rounded evergreen shrub to 5′ x 5′ after 6 years. In spring (and again in autumn) the whole bush becomes a cloud of fragrant white blossoms. They show up well with the finely divided leaves. Easy to grow shrub that is very forgiving. Drought tolerant when established and it has been hardy to near 0ºF. It takes very well to pruning which will increase both the shrubs density but the amount of flowers as well. The palmate leaves look like thin fingers or even bamboo especially as it becomes dense and layered. Moderate deer resistance. Perfectly adapted to the climate of Western Oregon. Full sun to part shade. Any reasonably well drained soil.
Excellent little selection of our locally native wildflower ‘Farewell to Spring’. To just 10″ tall this plant(s) become a solid dome of white flowers from May-August. Cute little cut flower. Full sun in rich, to average well drained soil with just light competition from other plants. Re-seeds reliably in open disturbed sites. A great native derivative for hell strips and even containers. Regular summer water – or it will shut down go dormant and think its time to set seed and then make its melon. Rough areas, cut flower. Oregon native plant.
Native annuals often get over looked in our gardens. They occupied vast stretches of the Willamette Valley and civilization has caused those displays to suffer. In our gardens they are precious reminders that we should include every category of native plant. Giant Blue Eyed Mary is one of our most delicate looking and stunning in floral detail, It makes a hazy cloud of beautiful blue and white small snapdragon flowers from late April to Mid June. A true annual that dies once the floral display is done. But leave the skeletons of the plant for several weeks longer to form and shed seeds for next years display. This 20″ tall grassy plant occupies open sunny sites as well as the margins of forests. In our gardens it appreciates open slightly disturbed soil. Seedlings germinate in autumn and over winter as small plants. They will heavily occupy an area about the size of a 9″ pie. Excellent plant to succeed mid and late spring bulbs. Water lightly after planting and to establish then none required. Native to the Portland city limits as well. Fantastic displays of this plant can be seen at Camassia in West Linn all through late spring. This is a very reliable re-seeder if you give it some open ground and check for slugs. Seedlings germinate quickly following the first rains and are incredibly cold hardy and drought tolerant. Don’t worry, they are from here, they know what to do. Attracts a wide variety of native pollinators including a wealth of smaller hover flies. Oregon native plant.
Columbia Coreopsis or Columbia tickseed is a locally native annual but more often biennial that is found along the Columbia River and into the gorge. Also, native throughout eastern North America. Its first season is spent as a rosette of curly, finely divided leaves that have a glossy sheen. The following early summer it erupts into groups of gold flowers, slightly reflexed petals and a red dot that surround a brown protruding cone. Loved by pollinators and they come en masse. To 22″ tall on average in bloom. For rich to average soil in full sun. The sun part is non-negotiable. Mix with native Oregon perennials and annuals such as Sidalcea virgata or Clarkia amoena var. lindleyi as well as Madia elegans for a summer long show. Very good butterfly plant. It has a scattered population in the Willamette Valley but should be grown here much more often. Self sows in open disturbed sites. Very prolific in bloom with clouds of golden flowers unobscured by pesky foliage. Nice cut flower. One stem can be an entire bouquet. light consistent summer water improves the show but this is a tough, climate adapted biennial. Moderate deer resistance. Oregon native plant.
We originally grew this wonderful vivid free blooming bat flower as an annual. But after years of growing it in the ground we’ve found that its remarkably root hardy. To 20″ tall forming a semi-woody shrublet it produces sprays of small but vivid flowers from May to frost. Full sun and rich, WELL DRAINED soil in the ground and patience- it takes a while to come back in spring- usually not until truly hot days appear in May. Once up- with regular supplemental water it zooms and blooms and resumes its previous stature quickly. Good drainage in a hot position seems to be the key as a perennial. Mine has happily lived in the ground in my garden in North Portland for 7 years- returning from the coldest winters. It will freeze to the ground below about 28ºF- but it always returns. Great seasonal plant in containers and it will draw hummingbirds from 5 counties around. Nice plant. Blooms continuously without intervention. My kind of plant.
Adorable little bulb that forms grassy colonies. Beginning in early summer and continuing to fall 10″ stems support amber orange intricate three petalled flowers. Each lasts just one day but new flowers appear seemingly from nowhere from the stems so do not remove- these stems can produce flowers for up to 6 weeks. Grassy medium green corrugated leaves accompany the flowers. Open sites with little competition from other plants. Sharp drainage in average to rich soil with regular summer irrigation. Full sun to light shade. Surprisingly cold hardy. Rock gardens, containers. Native to rocky plains in Argentina and Uruguay. It makes a great candidate for troughs and perennial containers where you can closely inspect the fascinating blooms. Mostly evergreen in our climate. Some deer resistance. Close iris relative.
Tufted Fairy Grass is an Oregon native that forms bright green fine clumps but is in its glory in bloom when tall vertical stems display hazy tan flowers at the tips. Easy to grow grass that improves under cultivation. Native to semi-shady to sunny aspects in rich soil that drains but also retains moisture. Adaptable to wet sites that dry in summer. To 10″ x 1′ as a clump of foliage but rises to 3′ tall in bloom. Very wild looking grass that can be massed for a hazy meadow effect, or placed in straight lines a modern aesthetic that combines a wild plant with spaced symmetry. Excellent among shrubs and with other wild looking meadow perennials. Winter deciduous. Cut back dead growth in spring. Relatively long lived. Native in the Portland city limits. Graceful. Winter deciduous. A pan global plant- this is our local form. Click on the link for a video of the dried seed heads. Oregon native plant.
If you are a victim of deer and rabbits let me introduce you to the vast world of Foxgloves beyond the weedy bi-ennial purpurea. They are all supremely deer and pest resistant in general. This relatively long lived perennial sends up 20″ spike of the softest yellow tubular flowers. They appear in late May- July. If you remove the spent spike often more flowers will occur. This soft color – staunchly in the realm of pastel goes so well with other colors. Its a harmonious hue and this is an adaptable plant. Rich to average soil- go for rich, with regular summer water. Requires FULL SUN to bloom its best. Excellent cut flower. Winter deciduous but it returns very early in spring. Plant with Euphorbia ‘Dean’s Hybrid’ for a close tone on tone color scheme. Very pretty with Penstemon heterophyllus ‘Electric Blue’. and purple/blue Salvia cohuilensis ‘Nuevo Leon’. Very cold hardy and easy to grow.
Shade plays by its own rules and to be honest flowers are often pretty modest. Therefore we rely on foliage to brighten dark corners and add texture and contrast. This elegant perennial is 18″ tall and arching stems have large opposite leaves delicately feathered in white. In spring small white bells droop gracefully along the stem. Deep, rich, hummus rich woodland soils that retain moisture. Regular summer water. Winter deciduous.
