Plant in full sun to shade. It can tolerate fairly dry conditions (coastal) but looks best with occasional to regular irrigation. This cultivar is particularly noted as being tolerant of water-logged conditions. Hardy to 15-20 F. It is possibly root hardy below these temperatures but can suffer severe foliage damage unless protected. It has been a popular hybrid since it was popularized in New Zealand in the 1950's. It is stable. A sport of this plant is the similar cultivar 'Cream Delight' which has more cream, less green and the red edge is less pronounced. Phormium cookianum 'Tricolor' was discovered in 1888 on the banks of the Wainuiora River and is considered to be a cultivar of Phormium cookianum ssp. hookeri. This plant was sold as early as 1939 by Duncan and Davies Nursery.  The information presented on this page is based on research that we have conducted about this plant in our library and from reliable online sources. We also consider observations we have made of it growing in the nursery's garden and in other gardens we have visited, as well how it performs in our nursery crops out in the field. We will incorporate comments that we receive from others as well and welcome getting feedback from anyone who may have additional information, particularly if they have knowledge of cultural information that would aid others in growing Phormium cookianum 'Tricolor'.     [MORE INFO]
