Gahanna was declared the Herb Capital of Ohio by the state legislature in 1972. Jane “Bunnie” Geroux spearheaded the effort and later founded the Ohio Herb Education Center. In celebration of this great distinction, the Gahanna Municipal Gardens were installed next to city hall at 206 S. Hamilton Road, in 1975. They were officially dedicated and named the Geroux Herb Garden in 2002. The gardens are open to the public.
