Acer circinatum

Acer circinatum

Vine Maple is perhaps our most beautiful native maple. Found from SW British Columbia to Northern California in the Shasta area. Its a pervasive understory tree throughout the western part of the state. It derives its name from its almost vine like habit in shade. This winding and sun seeking component leads to the most graceful natural forms. In full sun it is a compact, multi-trunked shrub. In autumn in both habitats it turns to shades of fiery orange and yellow and red. Vivid against the pure green trunks and stems.  One of the most dramatic places you will see this shrub is at 4500′ on Belknap crater on McKenzie Pass where it lives among the lava. In early fall the brilliant colors of the maples contrasts wonderfully with the black lava. Its very hot and very dry but  its also very high in elevation. The symmetrically serrated round leaves rival any Japanse maple. In shade established trees get by with little summer water. In the sun irrigation is welcome. Rich to average soil with regular applications of mulch. To 16′ tall in shade and again quite a bit shorter in full sun- very wide in shade. Avoid the reflected heat of south facing walls. This shrub/tree belongs on the north side or under substantial shade. Some deer resistance. Excellent underplanted with native ferns and Gaultheria. A common native that should be a more common ornamental. Tiny red flowers turn into sunny orange samaras by autumn and persist past the leaves.  Avoid very dry shade of un-irrigated over hangs. This is a semi-mesic maple.  Oregon native plant

Acorus gramineus 'Golden Lion'

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.

Adelinia grande

Great Hounds Tongue or Giant Pacific Forget-me-Not is one of our most remarkable native perennials. On the property where I grew up near Eugene it was native. There was a clump of this majestic perennial that was there for nearly my whole life. Unfortunately, we sold the property but this plant was still there last I checked. In the Willamette Valley and out into the Columbia Gorge you see these enormous blue flowers on a sturdy spikes in the dry areas under oaks. Often seen with Wyethia -Mules ears. Large fleshy leaves form a substantial clump. In early to mid spring 2′ spikes reveal outrageously large versions of Forget-me-nots. Established plants will then go dormant with summer drought. Adapted to xeric clay soils that dry in summer. Not only does it not require water established plants can resent it and rot. Place in a wild, unwatered part of your garden. Amend the soil lightly with compost and water in well. Pairs well, of course with other native perennials such as Sidalceas. In the wild it is accompanied by Erythronium oreganum , Lathyrus nevadensis, Fritillaria affinis, Dodecatheon hendersonii, and Ranunculus occidentalis. That is what grew with our patch, under white and black native oaks, with a madrone here and there. Impressive native perennial whose intense blue flowers are hard to convey in a photograph. It takes an extended time from seed to a growable plant. Patience because of limited quantities. Oregon native plant.

Agave parryi 'Flagstaff'

Agave parryi ‘Flagstaff’

From the very far north end of this variable species range in Northern Arizona near—‘Flagstaff’. High elevation form that is found above 7000′ in the wild. Very cold hardy moderately large Agave. Full sun and very well drained soil. You must amend the soil with pumice and gravel to avoid wet accumulating around the crown in winter. This is made all the more easy by placing on a slope. The rosettes should be tilted to shed winter wet. Very stiff and sharply tipped steel blue leaves form a rosette that is at first upright then spreads out a little. Remove leaves from deciduous plants that collect in the rosette in autumn- they blow in from god knows where and leaving them can encourage rot. Excellent in containers. Move containerized plants under an eave or overhang to keep it dry in winter. No water required after initial establishment. Beautiful form of this cold hardy species. High deer resistance.

Anchusa azurea 'Dropmore'

Anchusa azurea ‘Dropmore’

Alkanet, Italian Bugloss- neither name is very appealing but I’m here to testify that if you are a connoisseur of the color blue this big showy perennial is for you. To 4′ tall multiple spikes bear rich, deep, true blue flowers in one bodacious cloud. This form is not only a superior blue, but its a more reliable perennial. Most live 2-3 years but this often persists for longer. This borage forms a basal rosette of rough leaves- this is important to identify the inevitable seedlings- they are dark, dark green and spiny. Blooms first year from seed. A Spectacular plant for a young garden, a dry garden, wild border or in its most classic home the cottage garden. Full sun and average to enriched soil that drains quickly. Light consistent water to establish then drought adapted. Long, long blooming plant that often has bumble bees fast asleep in the cup shaped flowers. Very cool. Obvious pollinator gem. Very climate adapted plant.

Arisaema ringens

Cobra lily or Jack in the Pulpit from Japan with exotic striped flowers in mid-spring but the bold and glossy foliage steals the show. Forming large patches in rich, WELL DRAINED soil with regular summer irrigation. Shade- protect the amazing leaves from blasting sun. They will stand prominently up to 2′ tall- triple lobed, glossy and good looking. One of the more reliable of the genus in fact we think this is the best adapted Jack in the Pulpit for our climate.  Mix with other bold shade perennials. Mulch with compost annually. Disappears entirely in winter. A Xera favorite perennial.

Asphodeline lutea

Asphodeline lutea

You don’t see this perennial from the middle east very often in our gardens. Its a great, low water long lived plant with dramatic, showy flowers. Spikes to 4′ tall are clouds of large starry yellow fragrant flowers. Blooms appear in May and June and are showy for weeks. Grassy blue green leaves form a clump at the base. Rich, well drained soil with little to no summer water once established. Mass for a very showy effect. Remove spent flowers and you are left with relatively good looking low arching blue green leaves. Must have full sun and a bit of patience to bloom. We try to sell them in bloom to avoid the wait. Moderate deer resistance. Winter deciduous. Long lived.

Beesia deltophylla

Beesia deltophylla

Still relatively new this extraordinary perennial has so many fantastic attributes it will become indispensable in our gardens. Glossy concave heart shaped leaves emerge tinted black before settling to a deep forest green. The dense foliage is seldom bothered by pests and appears to be slug/snail resistant. Throughout the growing season 2′ spikes emerge over the dome of dense foilage with small white flowers. The over effect is cool sophistication in the shade garden. Slowly expanding to 2′ wide. Rich, moisture retentive soil with regular summer irrigation. Mix with Hosta, Hakenochloa, Epimedium. Semi-evergreen.

Flowers are always at a premium in shade, and late season bloomers for shade are not profuse. This wonderful white flowered form of this hardy Begonia is a sparkling white treat. Masses of snow white flowers on white pendant stems decorate the top of the plant from August to October. The foliage with leaves shaped like large deep green wings are an excellent back drop to feature the contrasting pure flowers. This is a wonderful and very different effect than the the much more common pink flowered selections. The purity of the flowers is divine and they seems to appear from nowhere often in the hottest days of summer. At our wholesale nursery I found myself stopping to look at this beautiful perennial every time I passed it. It is exceptionally pretty Part shade to high overhead shade in rich soil with regular summer irrigation. Though it will arrive smaller with less flowers without water. Not bothered by slugs or snails it rises with the opulent green foliage to about 2′ tall before  flowering commences. Very easy and long lived perennial. It persists with quite a bit of neglect. Mulch after planting to even out soil moisture. Avoid blasting reflected heat and drought.  Often self sows and also propagates by small bulbils. This is never out of control and is usually welcome. Forms expanding patches to several feet wide. Disappears entirely in winter, nada and it arrives late in spring (be patient) it is more than hardy to cold. Wonderful plant Thank you Peter for this plant.
