Caladenia excelsa
Caladenia excelsa is a rare Western Australian terrestrial orchid with one hairy leaf and up to three tall, cream to greenish flowers with long drooping tails. It grows from an underground tuber in deep sandy soil in forest and is hard to cultivate outside its native habitat.
Caladenia excelsa, commonly known as giant spider orchid, is a species of orchid endemic to a small area in the south-west of Western Australia. It is a rare species with a single, hairy leaf and up to three cream-coloured to greenish-cream flowers with long, drooping sepals and petals. It is one of the tallest spider orchids in Western Australia and, with Caladenia splendens, has the largest flowers of any Western Australian orchid.
The giant spider orchid is found between Dunsborough and Karridale in the Jarrah Forest and Warren biogeographic regions where it grows in forests in deep sandy soils.
