Phormium cookianum ‘Licorice & Lime’
Mountain Flax (Phormium cookianum) is generally hardier, smaller and softer leafed than the better know New Zealand Flax (Phormium tenax) but as all gardeners know, sports (different forms of a plant) where coloured pigments mask the chlorophyll in a leaf make somewhat less frost hardy plants.
This plant is relatively new to cultivation and although little tried is unlikely to be an exception so probably best near coasts and in large metropolitan gardens – London is always a good bet.
They need a reasonable amount of light and reasonably well drained soil.
To 3ft x 3ft after 3 years with exotic yellow flower spikes in mid summer.
Propagated by division or micropropagation.
Hardiness level Amber
