Libertia ixioides is naturally found throughout New Zealand from coastal lowlands to low mountain forests at an altitude of 600m (2,000ft) growing along the banks of water courses. 

It prefers a well drained moderately fertile sandy to light clay loam that is moist to dry and grows in an open sunny to semi shaded position and is drought and light frost tolerant.  

The New Zealand Iris is grown for its flowers and its clumping habit. It is planted in parks and small gardens along borders or in group plantings on embankments. It is suitable for coastal and low mountain regions establishing in 2 to 3 years from division. It is also planted in courtyards, commercial sites, rockeries, roof gardens and on embankments.

Note:
This plant is very simular to Libertia grandiflora differing with flowers that appear amongst the foliage and the seeds are not released immediately when the fruit is ripe and generally it is a smaller plant.
