Phormium prefers a rich, moist soil and a location sheltered from harsh winds, but once established, the plants really aren?t fussy about conditions.
Phormium can easily be grown in containers. Choose a rich, organic mix over traditional potting soil and keep the plants well watered in summer?s heat. Don?t allow the plants to experience frost. Phormiums can be grown indoors, either as house plants or under lights. The prefer cool temperatures in winter, but lots of sunlight.
