The Flax lily (Dianella revoluta) belongs to Liliaceae (the Lilyfamily). It is an evergreen perennial herb that is distributed in eastern Australia, from New South Wales to Victoria and Tasmania. It grows in various environments and can reach 30-90 cm in height. The leaves are broadly linear, curled inward, upright and crowding. From spring to summer, it grows long flower stalks with sparse panicles and blooms star-shaped blue flowers. The feature is that the color of the anther is black. After flowering, berries from dark blue to bluish purple are borne. Aboriginal people used it as a dye and knitted leaves. I chose this species because the leaves do not seem to have fallen, but there is a possibility that it is a yellow anther "Dianella caerulea".
