Nature's Weirdos: Australia's 5 Strangest Plants

Among the gum trees and rainforest trails, Australia’s native plants love to show off their quirks. From twisted stems to alien-looking plants, some of Australia’s native species are truly unique, found nowhere else on Earth. A rich variety of plants flourish across our varied landscapes, and while many species bloom barely noticed and rarely seen, others are so strange they’ll have you asking, “what on earth is that?!”

Here are five of Australia’s weirdest native plants:

1.Redcoats (Utricularia menziesii)

Utricularia menziesii, commonly known as Redcoats, is a carnivorous plant found only in the coastal areas of Western Australia. It features a red nectar chamber and tiny yellow bumps that look like anthers. This little wonder can grow up to 3 centimetres tall. As a carnivorous herb, Redcoats thrives in waterlogged soil and uses insect-trapping bladders tucked beneath its leaves. Each bladder holds water and has a door lined with sensitive hairs that guide unsuspecting prey toward the opening.

These clever traps often lure small aquatic creatures like mosquito larvae. Once caught, the prey slowly breaks down, feeding the plant in its otherwise nutrient-poor environment. The flowering season runs from June to September. As unique as it is, Redcoats isn’t houseplant material, it needs a soggy habitat to survive and doesn’t do well in dry conditions.

2.Sturt’s Desert Pea (Swainsona formosa)

With its alien-like look, Sturt’s Desert Pea (Swainsona formosa) is one of Australia’s most iconic desert wildflowers. Native to the arid inland regions, its flowers usually grow in clusters of five or six and reach about 9 centimetres long. The structure is striking, with deep red petals and a bold black centre known as the boss (fitting name, since it protects the important stuff and keeps everything running smoothly, just like your boss!)

This sprawling plant can stretch up to two metres in length and typically blooms from June to March, drawing in plenty of insects. Growing it at home can be a bit of a challenge, but it’s doable. Just remember, the word desert is a big hint – it loves hot, dry conditions and excellent drainage.

3.Daintree Satinash (Syzygium monospermum)

Unlike most plants that bloom from their branches, the Daintree Satinash (Syzygium monospermum) produces flowers that burst directly from its trunk.  Endemic to north-east Queensland, it thrives in the lush, humid heart of the Daintree lowland rainforest. These trees can grow up to 17 metres tall and have smooth, reddish-brown bark.

They produce edible fruit that usually ripens between September and January, along with soft yellowish-cream flowers. What makes this plant extra special is its role in the ecosystem. It’s a key food source for the endangered southern cassowary and has a unique relationship with ants, who make their homes in its trunk. This species is one of thousands of unique species in the Daintree rainforest, a place that has become the centrepiece of one of the world’s three major centres of endemism.

4.Fringed Helmet-Orchid (Corybas fimbriatus)

The Fringed Helmet-Orchid (Corybas fimbriatus) is one of 20 Corybas species found in Australia, part of a much bigger family with more than 100 genus of Corybas worldwide. It has a broad, egg-shaped to round leaf and a dark reddish-purple flower with fringed edges that look like tiny teeth. The flower itself is only 25 to 30 millimetres wide and can be found across southeastern Australia.

It blooms in late autumn and winter and offers a valuable nectar source for pollinators. You can grow it in your backyard, but it’s a bit picky. It needs good air circulation and a protected spot with about 50 percent sunlight during its active growing season to thrive.

5.Cranbrook Bell (Darwinia meeboldii)

Also known as Mountain Bells, the Cranbrook Bell (Darwinia meeboldii) is a standout with its bell-shaped bracts that are usually white with bright red tips. Native to Western Australia, these flowers can grow up to 30 millimetres long, and the plant itself can reach between 2 and 3 metres in height.

It flowers in spring and attracts a lively mix of birds, bees, and butterflies. While it can be tricky to maintain, especially during humid summers, it’s worth the effort. For best results, grow it as a grafted plant and keep it shaded from direct summer sun to help it bloom beautifully.

For all the green thumbs out there, we hope this list sparks some inspiration to grow a few of these garden-friendly oddballs. And for the nature lovers who enjoy a good wander, keep your eyes peeled, Australia’s weirdest plants are out there, waiting to surprise you.
