the.com/rose bush

means A woody, thorny shrub of the genus Rosa, cultivated for its fragrant, showy flowers.

from "Rose" traces back through Old English and Latin 'rosa' to a Mediterranean source word probably borrowed from Greek 'rhodon', which itself likely came from an older Iranian or Semitic root — the flower's name, like the flower trade, moved along ancient trade routes. "Bush," from Old English 'busc' and its Germanic kin, simply meant a shrub or thicket. Jam them together and you get a plain compound: the shrub that grows the rose — poetry doing none of the naming, botany doing all of it.
