Phormium cookianum subsp. hookeri 'Tricolor'
New Zealand flax
- Position: full sun
- Soil: fertile, moist, well-drained soil
- Rate of growth: average
- Flowering period: July
- Hardiness: frost hardy
Spikes of tubular, yellow-green flowers emerge in summer above clumps of sword-shaped, creamy-yellow and green striped leaves, with a thin red edge. This highly-decorative mountain flax makes a great all-year feature plant for a sheltered, sunny site. In frost-prone areas, over-winter container-grown specimens in a frost-free greenhouse or conservatory. - Garden care: Requires minimal pruning. In late spring remove any dead or damaged leaves and apply a balanced fertiliser and a mulch of well-rotted organic matter to stimulate vigorous new growth.
