The Brittlebush is one of the species that doesn't look as good if overly watered. It then tends to become overgrown and leggy.
The resin was chewed by the natives, and burned as incense in the early missions.
The leaves of the brittle bush produce a substance, toxic to other plants in the proximity.

Yellow daisy like flowers, up to 2 inches in diameter (5 cm), mostly in spring, and occasionally the rest of the year.

Culture:
Trim the spent flower heads as needed, and cut back in the fall to keep compact.
