What does bottlebrush mean?
A bottlebrush is a household cleaning tool consisting of a cylindrical head of bristles mounted on a long handle, designed to reach inside bottles, flasks, and other vessels whose narrow necks make ordinary washing difficult. The word also names a group of flowering plants: Callistemon species, native to Australia and widely grown in warm-climate gardens, whose dense, upright clusters of red flowers strikingly resemble the bristles of the cleaning implement — indeed, the plant was named after the tool rather than the reverse. In everyday use, "bottlebrush" most commonly refers to the cleaning brush, an unglamorous but essential item found wherever reusable glassware is washed by hand. The botanical sense carries a brighter connotation, evoking vivid colour and native wildlife such as nectar-feeding birds. The two senses are distinguished easily by context: one appears in kitchens and laboratories, the other in gardens, parks, and horticultural writing.

"He rinsed the decanter thoroughly after giving it a good scrub with the bottlebrush."
Any of various Australian shrubs or small trees of the genus Callistemon, bearing dense spikes of red flowers that resemble the cleaning brush of the same name.
"A bottlebrush planted near the veranda attracted lorikeets all summer."
Standard plural formation; applies to both the tool and the plant.
"The cupboard held several bottlebrushes of different sizes."
The bottlebrush tree earned its name because its crimson flower spikes look so much like the kitchen tool that gardeners often mistake one for the other at a glance.

Etymology of bottlebrush
The word bottlebrush is a transparent compound of "bottle" and "brush," both long-established English words, formed to describe a brush shaped for use in bottles. It arose as a descriptive coinage in English, likely during the nineteenth century when the tool became widespread in households. The plant genus Callistemon received its common name "bottlebrush" in the nineteenth century as well, named for the visual resemblance between its flower spikes and the cleaning tool. No deep classical root underlies the term; it is a straightforward English compound.
How bottlebrush is actually used
Both senses are standard in British and American English. The botanical sense is common in Australian English and in gardening contexts worldwide, while the domestic sense is the more familiar everyday usage elsewhere.
