Other forms: bushiest; bushier; bushily
Bushy things have the rounded shape and thick texture of a bush. You could describe your grandfather as having thick gray hair and bushy black eyebrows.
You can use the adjective bushy to describe all kinds of things — you might wake up with your curly hair looking quite bushy, or adopt a particularly bushy old cat from the animal shelter. Shrubs are usually bushy, of course, while other plants may grow tall and spindly or spread in a squat and bushy shape. In the 14th century, bushy meant "overgrown with bushes."
