Brunonia Australis

 

Native cornflower

Brunonia Australis - Native Cornflower is a perennial herb. The 10 cm. leaves form a cluster at the base of the plant, from which a 50 cms stem arises bearing a 30 mm domed cluster of around 50 little deep blue flowers, usually in Spring, but can be in Autumn. It can be difficult to get these plants established, but they can easily be grown from seed, and treated as annuals.

Flowering

From Mid Spring TO Mid Autumn

Usually the flowers appear in Spring, but sometimes flower in Autumn as well

 

Planting

From Early Spring TO Mid Spring

Plant in free-draining soil in a sunny, or partially sunny, site, after the risk of frost has passed

 

Propagate by division

From Early Autumn TO Mid Autumn

After approximately three years, once herbaceous perennial varieties have become established clumps they should be divided in order to retain vigour.. The simplest method is to carefully dig around the clump and gently pull it apart into fist sized pieces and re-plant immediately. The middle of the original clump should be discarded as this will have lost vigour and become woody.
