Flowering Cordyline from back garden

Cordyline is a genus of about 15 species of woody monocotyledonous flowering plants in family Asparagaceae, subfamily Lomandroideae. The subfamily has previously been treated as a separate family Laxmanniaceae,^[2] or Lomandraceae. Other authors have placed the genus in the Agavaceae (now Agavoideae). Cordyline is native to the western Pacific Ocean region, from New Zealand, eastern Australia, southeastern Asia, Polynesia and Hawaii.
The name Cordyline comes from the Greek word kordyle, meaning "club," a reference to the enlarged underground stems or rhizomes.^{[3]http://en.wikipedia.org/wiki/Cordyline}
