Ficus rubiginosa Australis - Port Jackson fig

Ficus rubiginosa 'Australis', also known as the Port Jackson Fig or Australian Fig, can be grown outdoors in frost-free coastal areas. In less favourable locations, it makes a very attractive houseplant or conservatory plant. Its ovate, glossy, deep green leaves create a soothing and sophisticated atmosphere in the home. Perched on a cinnamon-coloured trunk and crowned with a rounded, verdant canopy, this small tree adds character to a bright living room or well-lit office.

Ficus rubiginosa belongs to the Moraceae family, like all Ficus. Among its botanical synonyms are Mastosuke rubiginosa and Urostigma rubiginosum. It is an evergreen tree native to eastern Australia, particularly the regions of New South Wales and Queensland. In its natural habitat, it grows on the edges of tropical forests, in ravines, and on rocky hills. Its root system is capable of reaching deep for water between rocks. Ficus rubiginosa 'Australis' cannot tolerate temperatures below 5°C.

In the wild, Ficus rubiginosa can reach a height of 7 to 15 m and forms a large, bushy shrub. When grown in pots, the plant grows slowly and typically reaches around 1.50 m in all directions. It features a straight trunk topped with a dense, rounded crown. Its leaves are ovate to elliptical, measuring between 6 and 10 cm in length, with a dark green upper surface and a rust-coloured underside due to dense hairs. Although flowering is rare indoors, Ficus rubiginosa can produce small, globular figs that turn yellow when ripe. This variety, like other tropical ficus, may develop aerial roots, especially in conditions of high humidity. These roots, which descend from the branches towards the soil, add an attractive, exotic dimension to the plant. Indoors, their appearance is less frequent due to generally lower humidity, but with proper care, including adequate ambient humidity, it is possible to encourage their development. The name "rubiginosa" comes from the Latin "rubiginosus," meaning "rusty," referring to the rust-coloured hue on the underside of the leaves.

When grown indoors, Ficus rubiginosa 'Australis' requires abundant light, ideally indirect or filtered light. It prefers moderate to high ambient humidity and temperatures between 15 and 25°C, with no cold drafts. The substrate should be well-draining, and watering should be moderate, allowing the soil surface to dry out between waterings. Regularly misting the foliage is recommended to maintain adequate humidity and prevent the appearance of pests.

The sap of Ficus rubiginosa contains latex, which can be irritating to the skin and toxic if ingested. Therefore, it is advisable to keep the plant out of reach of children and pets.

With its striking presence, Ficus rubiginosa ‘Australis’ easily fits in a bright living room or spacious office. It is perfect for contemporary, bohemian, or tropical interiors. Plant it in a natural wooden container, such as a citrus crate or a large ceramic pot. To create a beautiful contrast, pair it with a Calathea orbifolia, with its large, graphic leaves, or a Philodendron scandens, with its trailing habit. This plant structures the space without overwhelming the entire room.
