    Nursery contributed plant descriptions

    This Australian flax is reminiscent of the New Zealand phormiums, but on a greatly reduced scale. Plants form handsome, evergreen clumps of upright, slightly arching strap-like blades to 3', and send up branching sprays of blue or violet star-shaped blooms in spring and early summer. Plant in sun or part shade in well-drained, fertile soil and provide moderate water. Hardy to 10F. Southeastern Australia, including Tasmania.
