Part of speech: noun

Definitions

1. A type of flowering plant characterized by cylindrical clusters of bristly, brush-like flowers that resemble a bottle brush

Etymology: Bottlebrushes are named for a household tool, not for any plant feature in particular. A bottlebrush is a brush with a long, narrow head of bristles, shaped to reach down into the neck of a bottle and scrub its inside, and the plant gets its name from the resemblance between its dense cylindrical flower spikes and that cleaning implement. The shrubs of the genus Callistemon, native to Australia, bear spikes of red, yellow or pink flowers whose long stamens stick out like bristles. The plural "bottlebrushes" is simply the plural of "bottlebrush", a compound of "bottle" and "brush", so the word is built from two plain English nouns with no borrowing involved. Its meaning rests entirely on that visual comparison.
