Eucalyptus grandis, commonly known as the Flooded gum or Rose gum, is a tall tree with smooth bark, rough at the base fibrous or flaky, grey to grey-brown. At maturity, it reaches 50 metres (160 ft) tall, though the largest specimens can exceed 80 metres (250 ft) tall. It is found on coastal areas and sub-coastal ranges from Newcastle in New South Wales northwards to west of Daintree in Queensland, mainly on flat land and lower slopes, where it is the dominant tree of wet forests and on the margins of rainforests.
Flooded gum is an attractive, straight-trunked tree much in demand outside Australia for timber and pulp, and extensive plantations exist in South Africa and Brazil. Within Australia, plantations exist in northern New South Wales, where seedlings have put on 7 metres (23 ft) of growth in their first year. The timber has a pinkish tinge and is used in joinery, flooring, boat building, panelling and plywood.[5] It has a straight grain, and moderate durability and strength, and is resistant to Lyctus borers. Hybrids with river red gum (Eucalyptus camaldulensis) are used to combat salinity.
Eucalyptus grandis has been grown successfully in plantations in wetter areas of Sri Lanka, particularly in the Badulla and Nuwara Eliya Districts. Many parameters of climate and soil are similar to eastern Australia, and it has grown well on plains as well as hills previously used for growing tea. Grown for its wood and ease of cultivation, it is the fastest growing eucalypt in the country.
The tree is too large for most gardens, but makes an attractive tree for large parks and farms, and can be used in riverbank stabilisation.

| Germination | 1. Place a single paper towel on a flat surface and spread the eucalyptus seeds onto the towel in an even layer. Place another paper towel on top of the seeds and then place the towel and seeds onto a plastic sandwich bag. Pour 2 tablespoons of water into the bag and seal it up. 2. Place the bag into a refrigerator that holds a temperature between 35F (+2C) and 40F (+4C) degrees. Keep the seeds in the refrigerator between one and two months. 3. Fill a seed tray with a potting soil until the compartments are 3/4 full. Place one to two eucalyptus seeds into each compartment and then sprinkle the tops of the seeds with soil until the dirt reaches the top of the seed tray. 4. Water the soil thoroughly with plain tap water. 5. Place the seed tray in a location that receives direct sunlight, and that has a temperature of between 60 and 65 degrees Fahrenheit. Keep the seeds moist and they should germinate in about one to two weeks. |
