More Information
Botanical PronunciationFOR-mee-um
LoreNew Zealand flax plants were used extensively by the indigenous Maori people of that region. The fibers inside the leaves led to the common name, flax, referring to the European fiber plant that is totally unrelated. Maori harvested the fibers and used the to weave cloth, mats and baskets.
Average Size at MaturityModerate growing; reaches 3 to 4 ft. tall and wide.
Bloom TimeOccasionally blooms in summer; prized for foliage.
Design IdeasThis vibrant colored flax is well suited to mid-century modern and post modern compositions for dramatic high contrast color and texture. A natural in tropical landscaping with large leaf exotics and hot colored flowers. Use to soften building edges and as foundation planting. Smaller stature makes this one suited to urban and tight suburban settings. It's a powerful way to highlight important places in the garden. In a more naturalistic setting in sizeable landscapes, plant in groups for massive effect. Works particularly well around pools, ponds and rock waterfalls. Makes a striking potted specimen.
