Little Leaf Gum is a handsome, graceful, cold hardy, obscure beautiful Eucalypt for our gardens. Extremely endangered in the wild it survives in just a few locations at high elevations – always above 3500′, in the SE Australian Alps. That alone gives us reason to grow this fantastic little tree. Fast growing small tree of very fine texture. To 22′ tall and half as wide in our climate. Single or multi-trunked the bark becomes glossy and shedding with time. Remarkably fast growing in youth, easily 3′-6′ in a single season- achieving tree status in just a few years. Wonderful fine textured evergreen that casts the lightest shade. Small groups of white flowers bedeck the stems in late summer and autumn- and sporadically through the year when older. Full sun and an open exposure. Very, very hardy to cold when established. There are two of this species planted along I-5 near the Woodburn Factory Outlets that have been there more than 35 years. They have endured temperatures near 0ºF at least twice in that locale with little to no injury. Takes summer drought but prefers a few good soaks when its really dry. Good garden tree. Dislikes shade. Open exposed location. The tree pictured is at the the Oregon Garden in Silverton. Excellent small garden tree.
Eucalyptus pauciflora ssp. debeuzevillei
Jounama Snow Gum is repeatedly one of the cold hardiest Eucalypts and it is excellently adapted to our climate. Gray/blue scimitar shaped leaves are pendant on a spreading umbrella shaped frame of a tree. Often the trunk forks just after emerging from the ground into multiple handsome stems. This increases the surface area where you can enjoy the ravishing exfoliating bark. Bark drops in late summer to reveal python like patches of taupe/grey/green and is showy through winter. In autumn the upper branches are decorated with small fluffy white flowers. One of the few Eucalyptus that will endure subfreezing wind- in fact this tree has been hardy to brief dips to 0ºF (-18ºC). Explosively fast growing when young to 35′ tall in just 7 years. Give it room. Light summer water in virtually any well drained soil- including clay. Do not stake. Let it produce its own sturdy leader. Sheds ice and snow like a champion. Though this is a subspecies of Eucalyptus pauciflora- a snow gum just like E. p. ‘Niphophila’ there are several differences from that tree. The leaves on E. p. debeuzevillei tend to be wider and more substantial than ‘Niphophila’. Also, that gum nearly always forms several trunks. This is less common with Jounama Snow Gum and in my experience it is a slightly taller tree. It can also vary in its habit from being very wide and spreading to skinny and fastigiate- its simply the luck of the draw and you cannot decipher this future habit as a seedling. Avoid heavy watering in hot conditions and site in a well drained place. Its completely drought tolerant and should be treated that way. Winter water when its cool is irrelevant. Overall it is a fast, healthy, and easy to grow tree in just a short amount of time.
Eucalyptus pauciflora ssp. niphophila
Snow gum is a wonderful cold hardy tree for the Pacific Northwest. Lance shaped gray foliage is pendant and handsome year round. This rapidly growing tree thrives in full sun and virtually any soil save for boggy conditions. In just a few years it develops amazing python mottled bark in tones of gray/tan/olive green. The bark sheds in mid-summer and can be a bit messy. Site accordingly. Grows 4′-5′ a year when young. Irrigation just increases this growth rate. Stake only when VERY young then let it form a sturdy trunk on its own. The vast majority of this Snow gum will form multiple trunks. Its possible to select one sturdy main trunk when young- pay close attention as they grow very fast. To 30′ tall and half as wide in 10 years. Snow gums have a weird habit of growing horizontally before reaching upwards. This is natural. Handles ice and snow no problem. Cold hardy to brief dips to 0ºF- but not lower. Mountains of Australia. White fluffy flowers in clusters in winter. Avoid all shade.
Spinning wheel gum is one of the prettiest of the cold hardier Eucalyptus. Named for its striking blue/gray perfoliate round foliage as a juvenile. In time as the foliage morphs to adulthood each new leaf becomes longer and more pendulous. A small tree in our climate to 18′ tall with a widely spreading crown. Fast growing tree, especially in youth. It may be damaged in our coldest winters- losing branches or even freezing to the ground if temperatures drop below about 8ºF. Re-growth which will be juvenile is rapid in spring and it can recover its full height in just two or three seasons. Damage occurs about once every 7 years- and slightly more often in rural settings. Best in the warmest possible part of the garden- and not for cold gardens or subfreezing wind prone sites. Excellent, highly aromatic cut foliage. White flowers line the stems like small sea anemones in winter. In time it develops a strongly weeping habit.
Feijoa (Acca) sellowiana
Pineapple Guava is a remarkable evergreen shrub that is cold hardy in the maritime PNW and is best used as a specimen in a warm position. Slow growing to 7′ tall and 5′ wide in 7 years it produces small but dramatic flowers in summer with bright red stamens and 4-6 swollen red petals that when eaten taste like fruity cotton-candy- excellent for children, fruit salads. These edible petals appeal to birds who unwittingly pollinate the flowers when they are noshing on the sweet treats. Handsome gray foliage. Full sun, regular soil and water. Occasionally fruits in our climate. The fruits are avacado green and about the size of a fuzzy kiwi. If they ripen by November into December they have a spicy sweet pulp- cherished by many. Becomes much more hardy to cold when established. Established shrubs take 5ºF with no damage. Good for hot aspects. Prune after flowering. Dynamic, handsome, and fun shrub to grow. High elevations in Brazil- other S. American countries. Must have full sun- completely intolerant of shade. Drought tolerant when established but regular summer water speeds growth/establishment. Syn. Acca sellowiana.
Yellow Mountain Kunzea is a rare alpine shrub from the very highest and coldest mountains and frosty valleys in the Australian Alps. A very fine textured low shrub with tiny gray leaves that most closely resemble an Erica. To 1′ x 3′ spreading in full sun and rich soil with regular summer irrigation. Bloom is a swarm of starry, stamen laden light yellow flowers. They can obscure the foliage in late spring. Not the easiest plant to establish and virtually unheard of in the United States. A little patience and some diligent water and you are good to go. Perfectly hardy to cold west of the Cascades. A beautiful member of the myrtle family that we are excited to have for sale. Moderate deer resistance.
Leptospermum cunninghamii ‘Silver Form’
Beautiful species of tea tree with tiny leaves of pure silver. Its been grown for eons in England- native to higher elevations in the Great Dividing Range. Great fine textured shrub for a dry and protected area. To 6′ x 5′ in 5 years one of the most silver evergreen shrubs in our climate. Blooms prolifically in June covering the whole shrub in white stars. Easy to grow in full sun and average, well drained soil. Light, consistent summer water. Will often have random flowers year round as well. Fast growing. Avoid the coldest sites- best in warm, sunny, gardens. Mix with other shrubs- especially yellow or chartreuse foliage which really makes this shrub pop. Listed as tender in some fairly famous publications…which don’t know what they are talking about. We’ve had this shrub planted at our very cold nursery in Wilsonville for more than 15 years….and there it still happily thrives. Moderate deer resistance.
Wooly tea tree is a cold hardy member of the myrtle family from Tasmania/Australia. The pewter gray small evergreen foliage creates a cloud like outline on billowing shrub. In June 1″ pure white single flowers spangle the boughs like snow. Woody seed capsules follow and persist. To 12′ tall and 4′ wide in 7 years. May be limbed into a small tree. Full sun and virtually any soil. Light summer water though very drought adapted. Excellent background shrub or screen or large informal hedge. Takes well to pruning which will not mangle the tiny foliage and becomes very dense as a result. Good bet where deer are a problem. Cold hardy to about 5ºF. Grows very fast with regular irrigation which is recommended for the first summer to establish. Does not tolerate shade of any kind. When using as a hedge plant about 2′ apart for a fast screen. Prune after flowering and again in autumn. Tasmania.
Rare shrub that is destined to gain popularity. From the highest elevations of the Australian Alps this large evergreen tea tree is beautiful in all of its parts. Known locally as alpine downy tea tree the fuzzy silver small leaves crowd the stems densely. In early summer masses of 1″ white flowers deck the boughs like snow. To 8′ x 8′ quickly it can also be trained as a small tree which highlights its incredible exfoliating trunks. Silver, copper, green and tan are all present after the bark sheds in mid-summer. Full sun and virtually any soil. Totally summer drought tolerant when established. Great hedging candidate. If sheared it becomes immensely dense. And cutting does not mangle the tiny leaves. Moderate deer resistance. So far undamaged at 5ºF. Photo credit: Evan Bean
Leptospermum rupestre ‘Squiggly’
One of the naturally cold hardiest species of tea tree. This form of Alpine tea tree from Tasmania has a distinctly upright habit. Cinnamon red squiggly stems support tiny pewter colored evergreen foliage. In early summer pink buds spangle the stems opening to pure white single flowers. So prolific is the bloom that the plant appears covered in snow. Vigorous growth to 5′ tall and 3′ wide in 6 years. Full sun and virtually any soil. Summer water is tolerated but far from necessary. Takes pruning incredibly well, including shearing and the leaves are so small that they remain unmangled. It quickly forms a dense hedge that is tough, incredibly dense and drought and cold hardy. Strongly deer resistant. Excellent shrub or hedge for rural areas. It tolerates a wide variety of soils and aspects. Leaves are aromatic when bruised. You achieve a much shapelier plant with even a minimal amount of tip pruning. otherwise it has a very wild habit. It has been undamaged by cold to 0ºF. Drought adapted. Tasmania. Click on the green link below for a video of ‘Squiggly’ in full bloom. Excellent shrub with a number of uses.
