Austral IndigoCategories » Flora and Fauna » Plants07th May 2017 | by the Friends of Nyerimilang (Indigofera australis) Austral indigo is a mid-storey plant growing up to 2 metres high. It likes full sun to semi-shade so can be grown under taller trees. It is susceptible to frost when young, but very frost tolerant after 2 or 3 years. An attractive garden plant, Austral indigo puts on a show of delicate pink flowers from August to December, that provide a pleasing contrast against its soft green leaves. Butterflies are attracted to it for its nectar and food for caterpillars.« Previous | Next »
