Brief SummaryRead full entry
Caladenia procera is a rare terrestrial orchid endemic to the southwest coast of Western Australia. It is known only from two sites near the towns of Busselton and Bunbury. The species is listed under the Australian Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) as Critically Endangered. The fragmented populations are threatened by human activities, grazing, and weed invasion.
Caladenia procera is a perennial herb. It has no roots and requires mycorrhizal fungi for germination, growth, and survival. The plant actively grows during the winter months (April-October) and spends the summer as a dormant tuber. It takes about 4 to 5 years for the orchid to mature and develop its first flower. Male Thynnid wasps serve as pollinators.
