River red gum
Eucalyptus Camaldulensis

​

There are over 400 species of eucalyptus or “gum trees” native to the Southern Hemisphere. Most eucalyptus are evergreen, fast-growing, have attractive bark, lush foliage, white flowers, and this species is no exception.

With a mature, stout appearance, this tree can grow up 120 feet tall and can even live up to 1000 years old. Its trunk has deciduous, peeling bark that reveals a smooth, light gray to white trunk and enjoys partial to full sun. It’s kept in check by winter frost and will tolerate most soils that are damp, heavy, and clay-based.

The oils or “gum” that come from the eucalyptus has been found to be beneficial for many different health benefits, including as cold and respiratory issues, dental care, infections and wounds, insect repellent, pain relief, as well as stimulating to the immune system.

This particular eucalyptus has been naturalized outside of Australia in warm-temperate (USDA zones 9-11) areas such as California and Arizona. Both their ornamental qualities and timber make the river red gum well-suiting for landscaping in both highway and large parks.

Part of the reason the river red gum does so well along waterways, floodplains, or in a park setting with wet soil is because it’s moderately drought-tolerant – just needing the occasional summer water. Its wide and deep root system taps into the subterranean water, making it a survivor in dry, harsh conditions.

Because it’s been known to have limb drop (possibly due to the nature of its fast growth), I would not recommend this tree around an area with lots of people such as a school, for example. If you’re thinking of planting a river red gum, reach out to your local certified arborist so you can better understand its needs. And please take care of the trees because they take care of us.
