Orchids in the genus Caladenia are terrestrial, perennial, deciduous, sympodial herbs with a few inconspicuous, fine roots and a tuber partly surrounded by a fibrous sheath.

The leaf is linear to egg-shaped, fleshy or leathery, lance-shaped to oblong, but is always simple, lacking lobes and serrations.

[2][3][4] James Drummond noticed the different tubers of some orchids and suggested that those that did not produce "droppers" be placed in a separate genus.

[10] The Western Australian species of Cyanicula occur throughout the south-west of the state, from as far north as Kalbarri to as far east along the south coast as Israelite Bay.

Blue orchids are found in a variety of habitats from winter-wet swamps and the margins of salt lakes to stony soils in woodland.
