Calothamnus quadrifidus, commonly known as one-sided bottlebrush is a plant in the Myrtle Family, which is endemic to the south-west of Western Australia. The common name alludes to the arrangement of the flowers in the inflorescence which line up on one side of the stem. It is a shrub with grey-green, pine-like foliage covered with soft hairs and red flowers in spring. This bush is growing in my garden and was planted about three years ago. This is the first time it has flowered.
