''Dianella caerulea'', commonly known as the blue flax-lily, blueberry lily, or paroo lily, is a perennial herb of the family Xanthorrhoeaceae, subfamily Hemerocallidoideae, found across the eastern states of Australia and Tasmania. It is a herbaceous strappy perennial plant to a metre high, with dark green blade-like leaves to 70 cm long. Blue flowers in spring and summer are followed by indigo-coloured berries. It adapts readily to cultivation and is commonly seen in Australian gardens and amenities plantings. ==Taxonomy== It was first described by English taxonomist John Sims in Curtis's Botanical Magazine in 1802. Its specific name is the Latin adjective ''caerulea'' "blue". The genus name is derived from the Roman goddess Diana, with a diminutive suffix -''ella''.〔 ''Dianella caerulea'' is highly variable species, with many forms found throughout eastern Australia.〔 Six varieties are known from the Sydney district alone. The species is described as having seven varieties, having been revised by Queensland botanist Rod Henderson in 1987 for the ''Flora of Australia'': *''Dianella caerulea'' var. ''assera'' grows as a taller solitary tufted plant to 1.8 m high, and is found from Nowra north along the New South Wales coast and Blue Mountains into Queensland. *''Dianella caerulea'' var.

''petasmatodes'' is a more mat-forming variant, which reaches 2 m in diameter and 1.3 m high. It is found on the far north coast of New South Wales into Queensland. *''Dianella caerulea'' var. ''producta'' is a taller variety to 1.3 m found from Nowra and Blackheath north through New South Wales and into Queensland. It has a greenish white to blue perianth. *''Dianella caerulea'' var. ''protensa'' is a smaller variant up to 0.5 m high, which grows as a solitary tuft. It is found from Nowra northwards through New South Wales into Queensland.
