Probably the smallest of the onion orchids, usually growing from 40-80 mm (2"-3"), but what they lose in size they more than make up for in numbers. They like the winter-wet zones on the edges of swamps and after a summer bushfire, can number in their millions, literally carpeting the ground. Being so small they are quickly smothered by other vegetation so these mass displays will only occur immediately after the fire and before other vegetation can dominate. But not to worry, as they can usually still be found in small scattered colonies in natural clearings for a number of years.
They will flower from late August through to November, and as they mature take on a yellowish appearance, particularly in drying conditions. This coloration makes them very noticeable and along with their size and numbers, very easy to recognise.
