Embothrium coccineum

Chilean Fire tree is a  brilliant and fun tree to grow in the milder parts of the PNW. Our seed strain is from established cold hardy specimens around Portland.  Moderately fast growing somewhat thin tree to 18′ tall and just 6′ wide in 10 years. In late spring (May) the tree is smothered in fascinating tubular hot orange/red flowers that are effective for a month or more. Semi-deciduous to deciduous in these hardy forms. Full sun and rich, to average well drained soil that has NOT been amended. Protea family it is sensitive to high nutrients- best in our native unimproved conditions. Light summer water. Hummingbirds manna. Long grown in the PNW- because it adores our maritime climate. Fantastic performance at the Oregon coast.

Grevillea australis

Alpine Grevillea is a cold hardy, handsome adaptable evergreen shrub that is good looking at all times. In late winter/early spring flossy white flowers explode over the bush and emit an intense honey fragrance. Each small leaf is olive/ochre green on the surface and silver below. Fine textured very rounded compact shrub to 4′ tall and 5′ wide in 5 years. Avoid enriched, over improved soil. Best in unimproved native or even poor soils with sharp drainage. Little water ever once established. Cold hardiest Grevillea taking temperatures to just near 0ºF with no problem. Good deer resistance.

Grevillea australis var. prostrata

Interesting plant for the collector. This is a low and mounding form of the hardiest Grevillea species. The tiny leaves are pointed, not rolled as in the species and they have a uniform tan green hue. In spring- after several years in the ground tiny flossy white flowers swarm the foliage from every leaf axil. They emit a penetrating honey perfume for weeks. VERY VERY slow growing to just 8″ tall and barely 2′ wide after 7 years. Full sun- no shade at all and average to poor well drained soil. It does just fine in native soil that has not been amended and its ultimate preference is for loam. Excellent small evergreen shrub for rock gardens, small spaces. More of a collectors plant. Useful on steep hillsides. Very hardy to cold enduring 5ºF with no issues. Little to no summer water. Moderate deer resistance.  Slow. Tasmania, SE Australian Alps. In the wild it cozies up to boulders to absorb radiant heat. This could be repeated easily in a garden. Rare. Limited quantities.

Grevillea juniperina ‘Firewoman’

About 15 years ago we planted this tiny seedling at the top of our propagation hill behind our wholesale nursery in Sherwood. After all those years and two trips down to 5ºF, numerous ice, snow, wind events it has remained completely happy and unblemished. This is closer to the species in form. To 4′ tall x 6′ wide in 5 years. Very prickly needles pose as the leaves forming a very formidable shrub. From January to July flaming red/orange flowers are curly and lick the tips of the stems like flames. And LOVED by hummers. Full sun to part shade, the very poorest, most well drained soil with no summer water once established. Takes clay soils on slopes. Completely drought adapted and it likes it that way. Great deer resistance. Long season of bloom on a charming architectural evergreen shrub.

Grevillea juniperina ‘Lava Cascade’

Low ground cover form of the Juniper Grevillea. Spreading to 6′ wide it rises to just 2′ when happy. Most of the time it is much lower. This selection is the most commonly seen orange form of this species. Spidery orange/red flaming flowers appear in clusters at the branch tips. The most likely bloom period is February-June- but older plants pump out sporadic flowers year round. Excellent on slopes- especially warm south facing slopes in a protected location. Surprisingly cold hardy enduring temperatures down to about 8ºF with no damage. Avoid subfreezing wind as well as boggy conditions and crowding fro other plants. Extremely drought adapted requiring no supplemental water after a year or two. Highly deer resistant. Excellent evergreen- but prickily shrub for Hell strips. Loved by hummingbirds. We have since introduced G. j. ‘Xera Ember’ which is a more compact shrub 2′ x 4′ and has merely deeply hued (bordering on red) flowers for a longer period. Gains hardiness with age. Pictured here with ‘Molonglo’.

Grevillea juniperina ‘Molonglo’

Juniper leaved Grevillea that is a low spreading ground cover. Grass green needle like foliage plays host and is often obscured by masses of curly apricot yellow flowers. They peak in late spring but occur almost any time of year. Poor, well drained soil in full sun with no supplemental water ever. To 2′ tall by 6′ wide in 5 years. Supremely adapted to the heat and drought of parking strips. Prickly foliage deters animals- and even people. Incredibly floriferous shrub with year round flowers peaking in spring. Loved by hummingbirds. Protect from subfreezing wind. No fertilizer.  Dense enough growth to smother weeds Best with total neglect. Loved by hummingbirds. Little water when established. Amazing in bloom.

Grevillea juniperina ‘Pink Lady’

A pretty shrub for a protected location.  Compact growing evergreen shrub with medium green needle-like foliage. To 2′ x 4′ in 5 years. Nearly year round but peaking in spring, copious light pink curly flowers are loved by hummers. Protected location in virgin, un-improved soil. Little to no summer irrigation. Excellent on a hot south facing slope- avoid crowding by other plants or an exposed cold site. Its possible that this is a hybrid and not pure G. juniperina. However, there is so much variability in this species that we are unsure. Best on slopes facing south. Extremely drought tolerant.

Grevillea juniperina ‘Xera Ember’

Our improved selection of the Juniper Leaved Grevillea with darker orange to near red profuse flowers and a more compact habit. To 2′ x  4′ wide in time the prickly grass green foliage of this spreading evergreen shrub allows the vivid curly deeply colored flowers to shine. Blooms nearly year round with a peak in mid to late spring. Loved by hummingbirds. Completely drought adapted- never needs supplemental water. Poor to average soil that drains but has never been amended or fertilized. Awesome candidate for a hot hillside or a protected hot south facing wall. Spectacular in bloom. Requests neglect- you should oblige. Hardy to around 7ºF.  Full sun.  High deer resistance.

Grevillea miqueliana var. moroka

Round leaf Grevillea is a great cold hardy species from the highest elevations in the mountains of SE Australia. Handsome wavy round evergreen leaves frame showy pendant flower clusters from January to June. The sunset colored flowers feature orange/yellow/pink in various incarnations depending on the temperatures. Loved by over wintering Anna’s hummingbirds. Any reasonably well drained soil that has NOT been amended. Native soils are perfect, and tolerant of clay as well as sand.  Great on slopes. Fast, large growing to 8′ x 8′ in 6 years. Little summer water required. Sporadic flowers appear year round. Avoid fertilizers. One of the best climate adapted Grevilleas that we have grown. Grows very fast with little water. Full sun and a hot position. Listed as endangered/threatened in Australia where it occupies just a half dozen sites in the high mountains. Extra reason to grow this fabulous multidimensional shrub that is good looking year round and blooms for a long, long period. No summer H20 when established. None.

Grevillea rivularis

Surprisingly cold hardy and wonderful Grevillea that is threatened in the wild. Crinkly, prickily, finely divided leaves create a haze of a frame to 5′ x 6′ in 6 years. This “cage” of foliage is intermittently decorated with soft purple flowers from spring to early autumn. These are tipped with a bright green style that is released in bloom. The flowers are often described as toothbrush like. Full sun to very light shade in average soil. Light summer water speeds growth but that is the only reason it is necessary. A protected location. Hardy to about 10ºF- and suffering no damage in the wild winter of 2016/17. Protect from subfreezing wind. Easy to grow with neglect and good siting. Same hardiness to cold as ‘Canberra Gem’. Give it room as it will steadily and methodically increase before you know it. Moderate deer resistance. AKA Carrington Falls Grevillea. Avoid fertilizers. If it never bloomed this shrub is fantastic for texture alone. Not for cold gardens- best with some urban protection. Very limited quantities.
