NEW ILS Coloring Books - Hot off the Press! 
Kudos to the ILS Youth Committee which has developed a lilac inspired coloring book. The idea behind the book is to use it as an educational and promotional tool for the society, hoping to encourage kids to get involved, generate awareness of the society and ultimately increase our membership. 

To help offset the price of producing and shipping the book we are asking for a minimum donation of $1.00 per copy. If you would like to order more than 10 copies the price will be $.50 apiece. Members residing outside the US and Canada will need to contact Karen McCauley for pricing. 

To order please email or call: 
Karen McCauley, Treasurer

Let’s Talk Lilacs 2018 ILS New England - Spring Thing
10:00 AM to 4:00 PM - Saturday June 2 at Carol's Collectibles Nursery in Swanville, Maine.
Syringa Plus is now co-located with Carol's Collectibles Nursery. 

Swanville is next door to Belfast a busy tourist stop in the summertime, but not so busy in the spring and yet it has all the amenities required to serve folks from "away".

We hope for an informal gathering, to spend some time chatting about lilacs and to arrange for visits to the private gardens of ILS members in that area of the state.

Other places to visit:
Coastal Maine Botanical Gardens
Univ. of Maine Lyle Littlefield  Garden - nearly 2,500 cold hardy plants, including lilacs (of course.) 

We will be sharing info for beginners and for the advanced lilac enthusiast. Come to share and add to your lilac experiences. We are all students, learning to better grow our beloved lilacs.

Free and open to the public. You need not be an ILS member nor a resident of New England, all are welcome.

Auction: Lilac and garden related donations are welcome. This income helps to pay for the event.
Please reserve your space; your RSVP is welcome, but not required.
We will order sandwiches and have drinks available, or you can bring your own picnic.
For more information and directions call Evie King 978-352-3301; or email oJack Alexander, ILS New England VP

Support scientific research while enjoying lilacs in your yard!

You are invited to join forces with the USA National Phenology Network and track the timing of flower and leaf events in a cloned lilac, thereby contributing to a historical data set 6 decades long. Individuals such as yourself have been tracking the timing (or phenology) of cloned lilacs across the country since the 1950's.
