Plants of Australia

The most isolated continent on Earth grew plants found nowhere else, and a few of them have made themselves at home in yours.

The continent

A continent mostly underwater

Australia is more than a country. Zoom out and it becomes Australia and Oceania, a region that runs from the Outback to the far islands of Polynesia.

That larger entity contains the nations of Australia, New Zealand, and Papua New Guinea, along with the thousands of islands in the Central and South Pacific that make up Melanesia, Micronesia, and Polynesia, the last of which includes the U.S. state of Hawai’i. Thanks to a unique physical geography dominated by the Pacific, and isolation from the rest of the world, Australia and Oceania holds a vast number of endemic species, plants and animals found nowhere else on the planet. The geography did most of the work:

In total land area Australia is the smallest continent, but most of Australia and Oceania lies beneath the Pacific, a body of water larger than all the Earth’s landmasses and islands combined
Oceania divides into three island groups: continental islands, high or volcanic islands, and low or coral islands
Australia’s landscape is dominated by the Outback’s deserts and semi arid land, while New Zealand features glaciers and Papua New Guinea, highland rain forests

During the last glacial period, sea levels sat low enough for travel, and many plants and animals reached the islands from southern Asia. After the seas rose and separated the landmasses, those species adapted to their individual island environments and produced new, endemic ones. Each of those histories ends in a care note. The conditions a species adapted to are the conditions it still expects from you, and they’re the reason our shelves hold plant science and plant culture side by side.

Worth repeating

Three fun plant facts about Australia and Oceania

Built for fire

Frequent wildfires have produced a remarkable adaptation in many species of eucalyptus, which make up three quarters of Australia’s forests: they resprout after fire, or carry seeds that survive prolonged blazes.

Seeds that sail

Coconut palms and mangroves, common throughout Australia and Oceania, produce seeds that can float on salty water for weeks at a time.

The kōwhai tree

The kōwhai, whose bright blossom New Zealanders chose as their national flower, has traditionally served as a source of medicine, yellow dye, and territorial markers for the Māori of Aotearoa, the Indigenous name for New Zealand.

Umbrella Tree

Schefflera actinophylla · Queensland and Northern Territory, Australia · Easy care

A plant both graceful and whimsical in appearance, the umbrella tree, so called because its compound leaves form rosettes shaped like small umbrellas, makes a great houseplant in almost any kind of space. While it loves bright light, it also does well in medium and even low light conditions. The fast growing shrub does show sensitivity to overwatering, though, so if you’re lucky enough to share your home with one of these beauties, err on the side of dryness.

Did you know? In its native Australia, where the wild tree develops striking fuchsia colored flowering branches that radiate from its center, it’s considered an environmental weed for its fast spread and the damage its roots can do to pipes and plumbing.

Weeping Fig

Ficus benjamina · Northern Australia, Southeast Asia · Intermediate care

The ficus family is large and full of popular houseplants, but Ficus benjamina, the weeping fig, is usually the one people mean when they say ficus. This elegant plant, chosen as the official tree of Bangkok, sports slender, light gray branches and dense, glossy dark foliage. Like some of its cousins, the weeping fig requires simple but conscious care, and it will definitely let you know when it’s unhappy. Under stress from movement, drafts, an inconsistent watering schedule, or poor light, this indoor tree might quite dramatically shed its leaves, and leave you weeping.

Did you know? The weeping fig is one of the best plants for improving air quality indoors, with some of the top removal rates for airborne toxins such as formaldehyde and benzene.

Kimberley Queen Fern

Nephrolepis obliterata · Australia · Easy care

If you want easily maintained verdant lushness in your home, the Kimberley queen fern may be the answer to your prayers. Unlike its better known cousin, the Boston fern, this excellent air purifier grows its fronds upright into space like a collection of drawn swords, making it the perfect occupant for an empty corner or a spot beside a doorway. Like all ferns, the Kimberley queen thrives in humidity and consistently moist soil, but this species tolerates a drier environment. Good news for pet owners: this Australian royal isn’t toxic to our four legged companions.

Did you know? Ferns have existed on Earth for more than 360 million years, arriving 200 million years before flowers. Many dinosaurs were exclusive herbivores that ate a diet of ferns, mosses, and conifers.

Isolation made these plants unlike anything else on Earth.
That’s exactly why they stand out in a room.
