One-sided bottlebrush

One-sided Bottlebrush (Calothamnus quadrifidus)

One-sided bottlebrush is common on the coastal plain and the Darling range, growing up to 2.5 m tall. Dark red flowers occur in spring and are grouped together on one side of the stems. ¬†They arise from a green base in four shoots – quadrifidus from Latin means “split into four parts”.
