Caladenia rosella

Status: Endangered on the EPBC Act list

Little Pink Spider-orchid

The Rosella spider-orchid grows 10 to 17 cm tall and has a single pale to bright rose-pink flower. It occurs in disjunct populations north east of Melbourne at Cottlesbridge, Research and Christmas Hills and, there is an unconfirmed record from near Stawell. In 2000 it was estimated that there were 120 plants in four populations. Typically found in heath woodlands and woodlands on well-drained, sandy soils, this species shoots in response to soaking autumn rains and becomes dormant in the summer after flowering in August and September. Invasive weeds and trampling by recreational activities are threats to the Rosella spider-orchid.
