It is a tufted Perennial plant, perennial Herbaceous plant, herb with sword-shaped leaves and blue-violet flowers.

Pink Lake (Western Australia)
Pink Lake (previously known as Lake Spencer) is a salt lake in the Goldfields-Esperance region of Western Australia. Although historically the water in the lake was visibly pink, as of 2017 it had not been pink for over ten years. Salt concentration is vital to Pink Lake's pink hue, and Pink Lake may turn pink again as conditions change. It lies about west of Esperance and is bounded to the east by the South Coast Highway. The dynamics of why a lake turns pink are very complex. External changes and weather conditions can affect the colour of the lake. Esperance's Pink Lake has lost its pink colour due to salinity changes caused by human activity. Description The distinctive colour of the water changes is a result of green alga ''Dunaliella salina'', halobacterium ''Halobacterium cutirubrum'', and/or high concentration of brine prawn. Once the lake water reaches a salinity level greater than that of sea water, the temperature is high enough and adequate light conditions ...
