Permaculture uses
The primary use in permaculture is as a windbreak and shade tree due to its height and dense foliage. The leaves contain citronellal, which can be used as an insect repellent and in essential oils. While not traditionally used as a food source, the leaves have been used in some instances to flavor teas or in potpourri. It has potential for timber and biofuel production. Care should be taken as the oil can be irritating to some people and pets.
Permapeople description
Corymbia citriodora, commonly known as lemon-scented gum, is a tall tree endemic to eastern Australia. It is known for its strong lemon scent.
Botanical description
Corymbia citriodora, commonly known as the lemon-scented gum, is a tall, slender tree endemic to eastern Australia. It typically reaches heights of 80-130 feet, with a smooth, white to pinkish bark that sheds in thin plates. The leaves are lanceolate, narrow, and strongly lemon-scented when crushed, measuring 4-8 inches long. The flowers are small, creamy-white, and borne in terminal panicles. The fruit is a woody capsule containing numerous small seeds. It is a fast-growing tree and relatively drought-tolerant once established.
Companion planting
Lemon-scented Gum can be a dominant tree, potentially shading out understory plants. Its allelopathic properties may inhibit the growth of some plants nearby. Consider its mature size and potential shading effect when planting near other species. Compatible plants are typically other drought-tolerant Australian natives.
Propagation methods
Propagation is typically done through seeds. Cuttings can be attempted, but success rates are generally low. Seedlings require well-drained soil and protection from frost in their early stages. Grafting can be used to propagate specific cultivars if they exist.
History and traditions
Traditionally, Aboriginal Australians used various Eucalyptus species, including possibly Corymbia citriodora, for medicinal purposes, such as treating wounds and infections. The lemon-scented gum's essential oil has a history of use in aromatherapy and traditional medicine for its antiseptic, analgesic, and anti-inflammatory properties. More recently, it has gained popularity in commercial essential oil production.
Usage calendar
Flowering typically occurs in summer and autumn (December to May in Australia). Seed collection follows flowering. Planting is best done in spring or early autumn to allow roots to establish before extreme temperatures. Pruning is usually unnecessary unless shaping or removing damaged branches.
