A vibrant form of Royal Grevillea that is slightly less hardy to cold than the species and requires a protected spot. Why grow this variety? It blooms, and blooms, and blooms. Rusty orange buds decorate pendant clusters that open to fresh orange. This plant sets tons of buds in summer and then releases them to the public through all the months of winter. Slightly smaller leaves are dusted in brown indumentum when young. To 8′ x 8′ very fast in average, unamended soil where water does not linger. Best in urban gardens with extra heat. It does not abort as many, if any flower buds in the summer drought. Excellent performance at the Oregon coast. Rounded upright and spreading evergreen shrub that remains handsome year round. Prune if needed after the last flush of flowers in spring. Winter flowers are a beacon to Anna’s Hummingbirds. Native to Australia where it was discovered near the Capital of Canberra. Nice cut flower. Water to establish then taper to once a month in summer. In colder gardens locate under the canopy of tall trees or near a warm wall. Full sun to light shade.
I selected this seedling because it is smaller growing but with relatively large VIVID orange flowers. To 4′ x 4′ in 6 years. Wavy curved leaves are olive green with a white underside. Blooms nearly year round once established. This selection requires a protected location in inland western Oregon but it absolutely thrives and loves the Oregon coast. Full sun and well drained soil with good air circulation. Water to establish then none required, very, very drought tolerant. An absolute magnet for hummingbirds and over wintering Anna’s find it a special treat. Do not amend the soil, native unimproved soils are ideal. For heavier soils plant on a slope. Established plants may have 1/3 of their mass removed following a blooming session. This will not only make a denser plant, it will also spur it to bloom even more. Moderately deer resistant. All hail DAVID BOWIE!
Xera Plants Introduction
Excellent introduction from Desert Northwest Nursery in Sequim, WA. This seedling of ‘Leanne’ exceeds that cultivar in several ways. First, its a decidedly smaller shrub with tiny, needle like deep green foliage. Second, its profuse flowers are a brighter and lighter yellow that is showy from a distance and great contrast with the foliage. This brand new plant is likely to reach 3′ x 4′ in 8 years. Moderately slow growing. Blooms appear YEAR ROUND and are a beacon to hummingbirds as well as gardeners in the dead of winter. Full sun to very light shade in average, un-amended native soils. Good drainage is helpful. Very little to no water once established. Extremely drought adapted. Beautiful, free blooming shrub that has great promise. Thanks, Ian. High deer resistance.
Impressive ground cover Grevillea that can be difficult to locate. To less than one foot tall it spreads out laterally easily 8′ wide in 7 years. The distinctly oak shaped leaves on this shrub emerge deep red before settling to green. All the while it is producing red upward facing “toothbrush” shaped flowers. These appear from February to August primarily but can pop off occasionally year round. All together it forms an amazing ground cover shrub that features fantastic foliage and flowers in a bold tapestry display. Cold hardy to a bit less than 10ºF- it appreciates successively colder frosts to harden off for its ultimate frost resistance. Full sun to part shade in average, well drained soil. Light summer water increases the growth rate- and it can zoom once established. Avoid crowding from other plants- it seems to require good air circulation. Excellent performance on gravel mulch. Large rock garden plant or hot slope cover. Protect young plants from temperatures below 15ºF- it can burn the foliage. Hardiness increases with establishment. The very short trunk emerging from the ground can be surprisingly stout- several inches in diameter. Cover with frost cloth- held down for wind protection during extreme arctic events. Drought adapted when established. A protected location. One of the coolest shrubs we can grow. A naturally occurring hybrid from the Blue Mountains. Excellent around and over boulders which add radiant heat during extreme cold. Should only be attempted in the mildest gardens.
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.
Xera Plants Introduction
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’.
This is an important hybrid that is among the best known in the United States of G. victorae x G. juniperina. A wiry rounded shrub with thin twisted green leaves that are rolled at the margins. Throughout the year a constant procession of orange/red flowers decks the whole frame. Loved by hummingbirds. To 7′ x 7′ in 7 years in average, well drained soil in full sun with little water once established. Not the hardiest Grevillea and has been superseded by cold hardier and superior varieties- such as ‘Neil Bell’. It is, however, an excellent evergreen shrub for the milder coastal regions. In Portland it is relegated to the warmest urban areas in protected locations. Easy fast shrub that you should protect from subfreezing wind inland. There are enormous specimens on the northern Oregon coast that adore that climate and it is naturally adapted to sandy soils. High deer resistance. Loved by hummingbirds. Prune to contain and maintain a compact habit. Hardy to about 13ºF- or slightly less hardy than ‘Canberra Gem’. Very floriferous.
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.
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.

Pretty and very large Grevillea that deserves the mildest parts of the garden. Small gray leaves are handsome and a great backdrop to the hot orange pendant clusters of flowers. Blooms year round with an especially large flush in spring. Loved by overwintering Anna’s Hummingbirds. Not the hardiest Grevillea- protect from subfreezing east wind- site on a south or west facing aspect. To 9′ x 9′ fast. Plant in UNAMENDED native soil- avoid compost and fertilizer. Supremely drought adapted. Avoid watering in summer. Excellent performance at the Oregon coast. Our stock plant which has thrived for 15 years in a very cold place is situated on a slope with the overhead protection of Douglas firs. Evergreen. High deer resistance.
