While most orchids grow on trunks and branches of trees or on rocks or even on the ground, there is a rare species that grows and blooms below the ground. It does not emerge above the soil, ever. Rhizanthella gardneri starts to grow when the first autumn rains fall. As it grows upwards, the surface of the earth above it cracks. This, along with the faint perfume that the orchid exudes. attracts insects like the fungus gnats and termites which crawl down to the flowers underground. This is one of the few plants known to employ termites as pollinators. It is found only in Western Australia.
