The phytoplasma is native to New Zealand flax, and early last century caused massive epidemics of yellow leaf disease in flax, destroying the once extensive flax swamps of Manawatu and contributing to the eventual collapse of the once flourishing flax fibre industry. [60], A tough fibre was extracted from the leaves of C. australis, and was valued for its strength and durability especially in seawater. [15], In spring and early summer, sweetly perfumed flowers are produced in large, dense panicles (flower spikes) 60 to 100 cm (24 to 39 in) long, bearing well-spaced to somewhat crowded, almost sessile to sessile flowers and axes. Cordyline australis flowers, commonly known as the cabbage tree, cabbage-palm or tī kōuka, is a widely branched monocot tree Flowering spikes of Cordyline australis in Cornwall, UK.
