Threlkeldia diffusa, also known as Coast Bonefruit, is a perennial herb which occurs in coastal areas and saline flats in Australia. It is sometimes prostrate or may grow up to 0.4 metres in height. The green flowers occur between October and November (spring) in its native range.
They grow well in a standard peat moss/sand which can be anything from 50% to 70% peat moss. There's no need to fertilize, as the plant relies on insects for food.
