Landscaping with Eucalypt Trunks: Australia is home to at least 700 Eucalypt species. Bark type, foliage, buds and fruits are used to identify them. Initially Eucalypts may be spilt into two broad categories. Those with smooth bark and those with rough bark. Gums are those with smooth bark and they come in a dazzling range of colours including grey, white, cream, pink and orange. Bloodwoods, Ironbarks, Peppermints and Stringybarks are all terms used to describe rough barked Eucalypts. The bark of Bloodwoods comes off in small many-angled flakes. Ironbarks have dark, deeply furrowed bark. Peppermints have scaly bark that peels in short strips. Stringybarks have bark, which may be pulled away in long strips.
If you have the room, planting a grove of Eucalypts with different bark type will create an eye-catching feature in your landscape. Planting the Eucalypts three metres to four metres apart will leave room for an understorey of native shrubs. Acacias, Banksias, Grevilleas, and Hakeas would be suitable. These shrubs will create added interest and provide habitat for native birds. They will have a maximum height of two metres and the Eucalypt trunks will be displayed above the shrubs.
These are some suggestions for trunk landscaping. Please note these species are either native to or suitable for planting on the Northern Tablelands of NSW. They should grow successfully in other areas but remember that almost all regions of the continent will have suitable local species with beautiful trunks.
