Anise is an herbaceous annual plant that grows to 3 ft (0.9 m) or more tall.
The leaves at the base of the plant are simple, between 1–5 cm long and shallowly lobed, while leaves higher on the stems are feathery pinnate, divided into numerous small leaflets.
The flowers are white, approximately 3 mm in diameter, produced in dense umbels.
Western cuisines have long used anise to flavor dishes, drinks, and candies.
The word is used for both the species of herb and its licorice-like flavor.
It is often wrongly attributed as fennel. (source)
So can rabbits eat anise?
Unfortunately they can’t eat it. Anise is not a good food for rabbits to eat and may make them sick if they eat it.
