The International Lilac Society was formed in 1971 to stimulate interest in the genus Syringa and to promote its use in public and private landscaping. Among its goals are to assist nurseries in providing the most desirable lilac cultivars and specimens, to maintain disease-free lilac stock, and to accurately identify lilac hybrids and cultivars.
