Indigofera Australis - 10x Seeds A beautiful ornamental shrub which is also a good plant for wildlife and a good nectar and food source for butterflies, bees and insects. It will flower through spring, with spires of pink to purple blooms. Growing to around 2 metres tall and wide, it can take neglect and some frost and drought. Given regular watering, a handful of slow release fertiliser each spring, and a light prune, it will grow into a lovely garden specimen. Easily pruned into shape. The leaves and stems are often used for natural dyes, and give a soft yellow colour.
