Growing New Zealand Flax (Phormium) for Dramatic Foliage

Pronunciation: form'-ee-um

This genus of two species is adapted to New Zealand's extremes—torrential rains, violent winds, seasonal drought, and scorching sun. Leaf fibers provide strength and flexibility; a tough coating conserves moisture and sheds water. Use in containers in cold areas, or as a hardy perennial in Zones 8–10. Striking foliage provides season-long color.

Plant in moist but well-drained soil. Forms large clumps over time, attractive in containers, beds, or borders. Divide older plants in spring as needed. In cold areas, pot up before first hard frost and overwinter indoors in an east or north window in a cool room. Keep on the dry side (but not so dry foliage withers) and withhold fertilizer in winter.
