Lilacia Park, an 8.5 acres (34,000 m2) garden, is located at 150 South Park Avenue, Lombard, Illinois. It specializes in lilacs and tulips. It is open to the public daily.
The garden was established by Colonel William Plum and his wife, Helen, who visited the lilac gardens of famous breeder Victor Lemoine (1823-1911), in Nancy, France. They returned with two cuttings (Mme. Casimir Perier, a double white, and Michel Buchner, a double light purple), which formed the basis of today's collection. After the Colonel's death in 1927 the grounds were left to the city as a public park.
The park now features more than 200 varieties of lilacs and 50 varieties of tulips, as well as a greenhouse, historical building, picnic areas, and drinking fountains.
