|Swan River blackbutt|
- Yarri redirects here. It can also mean Queensland Tiger. For the Aboriginal hero, see Yarri (Wiradjuri)
The tree typically grows to a height of 3 to 25 metres (10 to 82 ft) and has rough textured bark that is longitudinally furrowed. It produces white-cream inflorescences between July and August or November to February. The canopy grows to a width of around 8 metres (26 ft). One specimen of the tree located near Nannup has been recorded with a height of 43 metres (141 ft) with a canopy of 20 m (66 ft).
It is endemic to the southwest of Western Australia. The species grows well in gravelly soils with sandy clay or loam. It is often found in depressions, along stream banks or in valleys in the Peel, South West and Great Southern regions. It grows well in winter wet areas and other permanently damp locations.
It is in short supply as a harvestable timber as significant areas of its distribution are now covered by conservation reserves. In addition, even in forest where timber harvesting is allowed informal reserves placed around streams exclude Eucalyptus patens which predominantly occurs in the wetter parts of the landscape.
It is a viable tree to cultivate - and numbers of publications and websites have clear information on cultivation well away from its normal habitat
