In the garden
Libertia formosa belongs to the Iridaceae and is native to the Juan Fernández Islands, central and southern Chile and southern Argentina. Often called New Zealand satin flower, snowy mermaid or Chilean-iris, it is grown for its summer flowering and sits within the genus Libertia. Give Libertia formosa a site in full sun or partial shade and a soil that drains freely yet retains moisture; consistently damp, waterlogged ground should be avoided. A layer of organic mulch will help the soil hold even moisture through drier spells while still permitting free drainage. Position plants where they receive enough light to set flowers between June and August. In UK gardens it fits where soils stay reliably moist but are not stagnant, for example at the edge of perennial borders or alongside paths where soil texture allows free drainage. It adapts to a range of temperate spots provided root conditions suit its moisture needs. Expect flowering in the summer months and use that period to assess whether the siting needs altering to increase light or improve drainage.
