How to Identify a Eucalyptus Tree: Key Characteristics

Overview

Eucalyptus is an evergreen native to Australia. In the U.S., grown indoors as houseplants or outdoors on the Pacific Coast. Oil has medicinal/industrial/perfume uses but can be toxic if ingested in quantity. Distinct features make identification straightforward.

Step 1: Examine Leaves

Long, pointed, smooth-edged, leathery. Under magnification: oil-secreting glands throughout.

Step 2: Check Leaf Arrangement

Leaves alternate on branches.

Step 3: Look for Flowers

Buds appear as closed cups. Opening reveals no petals—just fluffy stamens.

Step 4: Find Fruit

Small woody capsules on flower stems. Split open to release seeds.

Step 5: Feel Bark

Stringy or flaky texture. May be deciduous, shedding outer layer seasonally.
