Origin and Breeding<br />

Spontaneous mutation: ‘PHOS2’ in 2007. The seed parent is characterised by a brown<br />

leaf colour and weak secondary colour expression. In 2007 a single whole plant<br />

mutation was identified within a production batch of ‘PHOS2’. It was isolated and<br />

subsequently asexually reproduced and found to be uniform and stable. This selection<br />

was later named ‘PHOS4’. Selection took place in Carabooda, WA. Selection criteria:<br />

presence of prominent leaf blade variegation. Propagation: vegetative,<br />

micropropagation is found to be uniform and stable. Breeder: Gavin James,<br />

Carabooda, WA.<br />
