Acacia obtusifolia, often called the stiff-leaf wattle or blunt-leaf wattle, is a type of tree. It is a perennial tree, meaning it lives for many years. This tree is part of the Fabaceae family, which includes many plants like peas and beans.

About the Stiff-Leaf Wattle

Acacia obtusifolia is a tree that can grow straight up or spread out. It usually reaches a height of 1.5 to 8 meters (about 5 to 26 feet). This tree is native to Australia, meaning it naturally grows there.

What it Looks Like

This wattle is closely related to another tree called Acacia longifolia. You can tell Acacia obtusifolia apart by its special leaves. Its phyllodes (which look like leaves but are actually flattened stems) have edges that feel a bit sticky, like they have resin on them.

When it Flowers

Acacia obtusifolia usually blooms later in the year compared to its relatives. Its flowers are also a lighter color. You can typically see its flowers from December through February.

Where it Grows and How it Handles Cold

Some groups of Acacia obtusifolia trees can survive cold winters. They can even handle temperatures as low as −6 °C (21 °F) and maybe a little bit of snow.

However, trees from warmer areas, like the coastal parts of Northern New South Wales, are not as tough. They can be harmed by frosts colder than −3 °C (27 °F). These trees often grow on high sandstone ridges, away from the very cold valley floors.
