Banksia is a genus of around 80 species in the plant family Proteaceae. They are native to Australia, happening in all but the most arid areas. Easily recognised by their characteristic flower spikes and fruiting "cones", Banksia are a well-known Australian wildflower and a popular garden plant. They grow in forms changeable from prostrate woody shrubs to trees up to 25 metres tall. They are generally known as Banksias or Australian Honeysuckle Trees.
Banksias grow as trees or woody shrubs. The largest trees, the Coast Banksia, B. integrifolia, and the River Banksia, B. seminuda, often grow over 15 metres tall, and may be up to 25 metres tall. Banksia species that grow as shrubs are typically erect, but there are several species that are prostrate, with branches that grow on or below the soil.
