Aaron's rod

Aaron's rod is the popular name given to various tall flowering plants (hag taper, goldenrod, etc.).

In architecture, the term is given to an ornamental rod with sprouting leaves, or sometimes with a serpent entwined round it (from the Biblical references in Exodus vii. 10 and Numbers xvii. 8).

Based on an article from a well-known encyclopedia published in 1911.

D.H.Lawrence wrote a novel called Aaron's Rod about an amateur flautist who left his wife to pursue his dream of becoming a professional musician.
