Divination with plants, herbs: Botanomancy is a method of fortune telling by burning the branches of vervein (now "vervain"; verbenas are said to have sacred boughs of certain medicinal plants) and brier, upon which were carved the questions of the diviner.

Variations included scattering the leaves of vervein (vervain) or heather in a high wind. Another method was by writing sentences on leaves that were exposed to the wind, and the divination would be gathered from those leaves which were left.

Interpretations were also made from the crackling sounds made when certain plants were thrown on the fire or crushed in the hands.

It is also considered a form of pyromancy or the interpretation of burned or burning tree branches and leaves.

Botanomancy is also considered a general term for divination which uses any plant or plant part.
