Eucalyptus camaldulensis is the most widely distributed eucalypt in Australia and the tree that defines inland river country. The River Red Gum builds a massive spreading crown over a smooth trunk that sheds in cream, grey and rich red-brown, and can live for five hundred years or more.
Eucalyptus camaldulensis grows fast at 1 to 2 metres per year, reaching 20 to 45 metres tall and 15 to 25 metres wide. This is a tree for rural properties, parkland and revegetation on a landscape scale. It should be kept well clear of buildings, since mature limbs can and do shed without warning.
This Australian native grows in full sun and tolerates light to moderate frost once established, along with drought, flooding, heavy clay and moderate salinity. It provides critical hollow-bearing habitat for parrots, owls and gliders as it ages.
Frequently Asked Questions
About Eucalyptus camaldulensis
How big does the River Red Gum grow?
Eucalyptus camaldulensis reaches 20 to 45 metres tall and 15 to 25 metres wide. It is a very large tree suited to rural properties, parkland and revegetation, not suburban blocks.
How fast does River Red Gum grow?
Very fast, at 1 to 2 metres per year in suitable conditions, particularly where roots can reach reliable groundwater.
Is it safe to plant near buildings?
No. Mature River Red Gums are known for shedding large limbs without warning. Site them well away from buildings, driveways, camping areas and anywhere people gather.
Does River Red Gum tolerate flooding?
Yes. It naturally occurs along inland watercourses and floodplains and tolerates periodic inundation better than almost any other eucalypt.
How long does a River Red Gum live?
They routinely live several hundred years, with some documented specimens exceeding 500 years. Older trees develop the hollows that many native birds and mammals depend on.
Is Eucalyptus camaldulensis an Australian native?
Yes. It is the most widely distributed eucalypt in Australia, occurring in every mainland state along watercourses and floodplains.
How far apart should I plant River Red Gums?
Plant 15 to 20 metres apart for a revegetation or avenue planting, and keep them a minimum of 25 metres from any building or structure.
