Australian Native Wildflower as Garden Specimen

 

Comment

Dianella tarda occurs in New South Wales and Victoria where it is classified as vulnerable and South Australia where it is extinct or endangered. The plant opens its flowers only in the late afternoon when the native Amegilla or Blue-banded Bee appears (see second reference below). The stamens are ‘buzz-tuned’ to the frequency of the bee’s wings to facilitate maximum pollen transfer.
