Caladenia arenaria
A deciduous ground orchid from the sandhills of southern New South Wales, growing from a single tuber that is replaced each year. It is endangered in the wild, so it is best left to specialist conservation growers.
Caladenia arenaria, commonly known as the sand-hill spider orchid, is a plant in the orchid family Orchidaceae and is endemic to New South Wales. It is a ground orchid with a single, densely hairy leaf and one or two white or pale yellow flowers with maroon tips. Formerly much more widespread, it is now only known from about two thousand individual plants in five locations in the Riverina area and is classed as "Endangered".
Sand-hill spider orchid grows in sclerophyll forest and on sandhills, usually under cypress pine trees. Its range used to extend for 500 km (300 mi) from Deniliquin to Yass and Mudgee but is now only known from five locations between Urana and Narrandera.
