About ILS

ILS Mission and Purpose:
The following is taken directly from the by-laws of the International Lilac Society:


The purposes for which the Corporation has been organized are as follows:  It is intended that the membership in this not-for-profit Corporation will be comprised of people who share n particular appreciation and fondness of the lilac. By the exchange of knowledge, experiences and facts gained by Members, it is proposed that the individual Members will increase their knowledge of the lilac and thereby help to promote a broadened public understanding and awareness of the genus Syringa L. The thrust is to be three-fold; through education, publication and research.

A lilac in every garden. . . the world over!

Welcome to the International Lilac Society (ILS). ILS was incorporated in the State of New York in 1974. Each year, we hold an annual convention at rotating sites at (we hope!) the time of lilac bloom.  

  • ILS publishes a quarterly journal titled (what else?) Lilacs. Each member receives a copy of each journal. 

  • ILS is made up of people from all over who appreciate and promote lilacs.  We include nursery staff, educators, professional and amateur gardeners, landscape architects, scientists, staff of arboreta and display gardens, anybody who appreciate lilacs--and anybody who appreciates them!

  • ILS is administered by a Board of Directors that is elected by the membership.  The 15-member board elects officers of our corporation.  We have a President, Executive Vice-President, Secretary, Treasurer, Editor, Executive Vice-Presidents for Canada and Europe, and Regional Vice-Presidents distributed around the globe. 

  • ILS also maintains committees for certain important activities, including research, publications, audits, propagation, and so on. 

  • ILS is governed as a 501c(3) (non-profit) corporation under the laws of New York State and the United States of America.


Nicole Jordan, President

Nicole was elected as our President in 2006 and has been re-elected since then.  A native of France, she resides in Virginia with lilacs and many other beautiful plants, as well as some friendly animals.

Brad Bittorf, Executive Vice-President
Brad was first elected to a five-year term as Executive Vice-President in 2005, and was most recently re-elected in 2015.  He lives near Tucson, Arizona where he has had some success in getting lilacs to bloom.  He will be happy to tell you about desert lilacs living in the shadow of citrus trees and cacti!  E-mail him at ILSExecVP@gmail.com.
