Orchids

By Noel Rosten Reviewed by Wendy Grimm Australian Plant Society

Orchids are herbaceous plants. More than thirty species have been found in the Park. At least seven species use trees or rocks as hosts (epiphytes). They use their host only as support, not for food. The remainder are orchids that grow in the ground (terrestrials). Spring is the main flowering time but every month will find one or two in bloom.
