Water Daisy

Olearia hygrophila, Family Asteraceae, also known as Swamp Daisy or Water Daisy, is a
soft-wooded shrub with lax growth to 2 m high, supported by surrounding vegetation. The
leaves are alternate, linear-elliptic, 2.5Ð7 cm long and 0.5Ð2.5 cm wide, attenuate at the base,
and with margins entire or with a few sparse teeth. Flower heads are around 2 cm across, with
white rays and yellow disc (Stanley & Ross, 1986; Bostock & Thomas, 1992). This species is
difficult to locate in habitat until flowering, which has been recorded from July to September
with a few flowers still evident in November (Sparshott & Bostock, 1993).
