Certainly one of the easiest to grow eucalypts for cold climates, the Omeo Gum Eucalyptus is a widely adaptable and stunningly gorgeous eucalyptus. The rounded leaves look nearly tropical on the square stems when it is young and the purplish blue new growth has caused many a nursery employee and customer to stop and stare in amazed wonderment for more than just a fleeting moment! Omeo Gum is unique for its ability to grow in baking hot dry deserts as well as the humid and wet east coast, and often withstanding waterlogged soils and even a bit of shade. Very unique attributes for a Eucalyptus! It’s as gorgeous in its mature form as it is in youth and deserving to be much more widely planted anywhere temperatures don’t dip below 0ºF.

One of the hardiest species of Eucalyptus, Cider Gum Eucalyptus Tree is prized for its round and attractive, fragrant, grayish-silver foliage. With annual pruning you can grow Cider Gum as a large shrub and keep these round, juvenile leaves. Allowed to grow tall, it will quickly become an attractive, upright tree and the foliage will become long and lance shaped. Looks amazing planted next to Arizona Madrone!

A particularly glaucous blue selection of the beloved Eucalyptus gunnii, this seed strain named ‘Blue Ice’, will vary slightly in how blue its leaves are but all are a wonderful grey to blue green color. Grows to a similar size to other Eucalyptus gunnii seedlings and appears to be just as cold hardy.

Another exceptional subspecies of Eucalyptus pauciflora, the Jounama Snow Gum (Eucalyptus pauciflora ssp. debeuzevellei) has proven itself a particularly cold hardy selection for the Pacific Northwest. The peeling, flaking bark is just as fantastic as the other snow gums revealing a multitude of colors in late summer. Blows birch bark out of the water, and without all the many disease and climate-adapted issues of that over-used (in our city anyways) genus. This subspecies typically grows a bit larger than the niphophila subspecies or Eucalyptus pauciflora, and also has slightly wider leaves. Give it no summer water and room to grow in full sun.

A simply stunning eucalyptus that has perhaps the most entrancing foliage of any species in the genus (big claim, we know!) Foliage is stacked tightly and geometrically along the stem and is silvery blue and somewhat similar to the Baby Blue eucalyptus so adored by florists. The Bookleaf Mallee grows as a small and multi-branched eucalyptus which they often refer to as a mallee down under. Pale yellow flowers encircle the stem on last year’s growth and look spectacular against the silvery blue foliage. The only drawback on this species is it’s not quite completely cold hardy here! It can tolerate light frosts down to 20 F. and we’re hoping that the presence of its lignotuber might make it possible for it to sprout back after being damaged by frost. Mulch heavily and site in a warm spot. In frost free climates it is one of the most choice small eucalyptus you might ever come across.

Native to the swamps and mountain valleys of New South Wales, the Mountain Swamp Gum is one of the few eucalyptus that thrives in wet, heavy soils. Leaves are very broad for a eucalyptus with a gorgeous red tint and are especially aromatic and rich in essential oils. Bark is dark, peeling and very attractive.

One of the most beautiful and one of the largest of any eucalyptus that we grow. In Portland Mountain White Gum specimens up to 60′ tall with a large spread can be found around town. Grows rapidly in youth, up to 6 feet a year and eventually develops its gorgeous powdery white bark as it matures. Foliage is sickle shaped, deep glossy green and incredibly fragrant when crushed or blowing in the summer breeze.

Watering when young produces rapid growth, though drying the plant off towards the end of summer helps it to go dormant and harden off any tender new growth for winter. Once established it is very drought tolerant and requires no water. Plant in a location where it has room to spread and in full, all day sun.

Latin Name: Eucalyptus dalrympleana
Site and Soil: Full sun and well-drained soil. Very drought tolerant once established and will need little to no supplemental watering during the summer season.

Bloom Time: Winter

Little Leaf Gum Eucalyptus has proven itself an incredibly resilient and hardy eucalyptus for our climate. The species is extremely endangered in its native SE Australian mountains which is all the more reason for us to grow it here and preserve this incredible and versatile little tree. Trees can be single or multi-trunked with bluish-green leaves and gorgeous purple new growth. The texture on mature trees is similar to an olive tree but at twice the growth rate! Casts very light shade and prefers full all day sun.

Established Little Leaf Gum specimens can be seen throughout the Northwest. A couple trees along Interstate 5 by the Woodburn Factory Outlets have withstood every winter storm that’s been thrown its way for over 40 years (including the 2024 January arctic blast)! And for a more easily approachable specimen, you can visit the Oregon Garden in Silverton and check out One Green World’s display garden while you’re there!

Kybean Mallee Eucalyptus is the ideal Eucalyptus for small spaces, growing to just 15′ or so and growing very quickly when young. The evergreen leaves are glossy green and hang elegantly from the branches year round! White winter flowers line the branches in winter and the bark is a smooth glossy grey. Almost always a multi stemmed small tree and hardy to at least 5ºF without damage.
