Melaleuca gibbosa is a member of the family Myrtaceae. Its common name is Slender Honey-Myrtle.
M. gibbosa is a medium sized, dense rounded shrub 2 metres high to 2 metres wide with attractive foliage of small sessile ovate to obovate leaves. Leaves are aromatic when crushed. In Spring and early Summer it bursts into small dainty mauve to pink flowers which fade to white. In the wild it is found along the coast South Australia, Kangaroo Island, Victoria, Tasmania and Flinders Island. It is found in heath land in swampy areas and often over limestone.
M. gibbosa bark is grey and hard. The small leaves are ovate to obovate, sessile and blunt and arranged in opposite pairs with each pair of leaves at right angles to each other (known as decussate). Flowers occur in up to 10 pairs per spike and have numerous stamens. The flask-shaped fruits are woody and become embedded in the stem. Seeds are retained in fruiting capsules.
This plant is adaptable and easily grown in most soils in temperate areas of moderate to high rainfall. It is drought hardy, frost resistant and tolerates waterlogging. M. gibbosa can be grown from seed and seeds require no treatment before sowing. Seed is easy to collect and is best collected from fruit capsules which are 1 to 2 years old. After collecting seed, place into a non-airtight container. Sow thinly and germination takes about 14 days approximately. It can also be grown from semi hard wood cuttings taken in December to March. Use a rooting hormone such as Clonax gel purple 2000/IBA to establish cutting. Plant out in full sun to part shade. M. gibbosa is basically a low maintenance plant but you can manage shape and size with regular light pruning.
