Environment

Widespread and often locally common; frequently growing in open sites on forested ridges and slopes among litter and shrubs in freely draining clay loam, stony loam and gravelly soil. It also occurs in coastal scrub and heath in leached sand and under sheoaks in stony soil, rarely in moss and lichen pads on granite rocks. At some sites it grows in exposed patches of quartz or quartzite chips and colonises disturbed sites such as track margins, old quarries and gravel scrapes. In New Zealand it grows in litter and moss under shrubs near geothermally active ground.
