Oxalis magellanica It is indigenous to New Zealand (North, South, Stewart, and Chatham Islands), Australia and South America. It is found from coastal to montane areas where it is mainly confined to indigenous forested habitats, though sometimes extending into the alpine zone. A species of riparian habitats, usually found within the flood zone of streams and rivers, and around the plunge pools of waterfalls. Provided its habitat is permanently moist it may be found growing in full sun but it is more usually seen in semi-shaded situations. Easily recognised by the preference for moist riparian habitats in indigenous forest; lack of bulbils; rhizomatous or stoloniferous habit, with shortly erect stems; glaucescent to dark green leaves and large solitary white flowers from September - March (sometimes year round). Does best in semi-shade in a permanently moist soil. It does not cope with drying out. An attractive, non-invasive species that forms patches of up to 70cm across.
