About

Caladenia rosea is a plant in the orchid family Orchidaceae and is endemic to relatively inaccessible, high lateritic plateaux in a high rainfall area in south-western Western Australia. It is a terrestrial orchid with a single hairy leaf and up to three pink flowers on a thin, sparsely-hairy stem. It is similar to Caladenia flava but is distinguished by the perianth being pink to dark pink with prominent red striping and spotting on the dorsal sepal and lateral petals.

Caladenia rosea mimics Hypocalymma robustum (Myrtaceae) in terms of flowering time, colour and scent.

Where it grows

Caladenia rosea grows sympatrically with Caladenia lateritica in shallow lateritic regolith that overlays massive bauxite. The open jarrah (Eucalyptus marginata) and marri (Corymbia calophylla) woodland has an understory of
