The black sheoak (scientific name: Allocasuarina littoralis) is a special tree found only in Australia. People also call it the black she-oak or river black-oak. It's usually a medium-sized tree, growing up to 8 meters (about 26 feet) tall. Sometimes, it can even reach 15 meters (about 49 feet)! In very windy coastal areas, it might grow as a tough, bushy plant instead of a tall tree. Its name, "littoralis," suggests it grows near the coast. But this tree is quite adaptable and can grow well both near the sea and further inland.

What Does the Black Sheoak Look Like?
This tree is an evergreen plant, meaning it keeps its green parts all year round. It belongs to a group of trees called Casuarinas.
Special "Leaves"
The black sheoak has very unique "leaves." What look like long, thin leaves are actually modified branches called branchlets. These branchlets are about 5 to 8 centimeters (2 to 3 inches) long and very narrow, less than 4 millimeters wide. The tree's true leaves are tiny, usually smaller than 1 millimeter. You can find these tiny true leaves at the very tips of the branchlets.
How Fast Does It Grow?
The black sheoak is a relatively fast-growing tree. It can grow up to 80 centimeters (about 31 inches) in a single year! Because it grows quickly, it's a great choice for planting along roadsides.
Flowers and Reproduction
In spring, the female black sheoak trees produce showy red flowers. Most black sheoaks are dioecious (say: dy-EE-shus). This means that a single tree will have either all male flowers or all female flowers, but not both. So, you need both a male and a female tree nearby for them to reproduce.
Where Does the Black Sheoak Grow?
The black sheoak is found in several parts of Australia. You can see it growing naturally in:
This tree often grows in woodland areas. Sometimes, you might also find it in tall heath environments. It's quite tough and can grow well even in sandy or other poor types of soil.
