Banksia seminuda, the river banksia, is a tree from southwest Western Australia that grows along river and creek edges and is often mistaken for swamp banksia. It is a vigorous, adaptable plant that does best with moisture and sun, and it can self-seed, so plant with care near bushland.
Banksia seminuda, commonly known as the river banksia, is a tree in the family Proteaceae. It is found in southwest Western Australia from Dwellingup (32°42′ S) to the Broke Inlet east of Denmark (34°57′ S). It is often mistaken for, and was originally considered a subspecies of, the Banksia littoralis (swamp banksia). Stephen Hopper described the subspecies remanens as a short-leaved shrubby form found in the coastal sands below granite outcrops in the Walpole-Nornalup National Park. However, George does not feel this form warrants taxonomic recognition as it lies within the normal variability of the species and there was no clear distinction between it and the other populations of B. seminuda.
Banksia seminuda is a vigorous and adaptable plant. There are reports of seedlings coming up near cultivated plants in Victoria, which suggests caution should be advised if planting near bushland.
This tree is found on the fringes of the rivers and creeks in jarrah, marri and karri forests, between Dwellingup and Denmark.
