Is easy to recognize by its glossy leaves that are edged with small white teeth and curved to form a sharp tip. This prickly protection is most probably to discourage animals and insects from taking a bite. It is an evergreen, much branched perennial that grows to about 60 cm high. The branches are almost entirely covered with the shiny, dark green leaves. The stiff little leaves are oval to triangular in shape, pointing downwards away from the stem. The flowers are usually mauve with a bright yellow centre, but white flowers are also occasionally found in the wild. This plant can be considered tender to frost, and in very cold areas it needs to be planted in a warm protected position.
