Summer 2015 Low

Summer 2015 A Publication of the Maryland Native Plant Society Volume 6, Issue 2 Letter from the President A Publication of the Maryland Native Plant Society Dear Members, My first six months as your president have been quite full. As I mentioned in January, one of my goals is to reinvigorate chapters throughout Maryland, and that has already begun. Last fall we held our annual conference in Cecil County and were treated to wonderful presentations and field trips that increased our knowledge of this diverse area. Our Northeast chapter, which includes Cecil County, has recently been revived by Tracy Ripani. She has been putting together programs and field trips with the help and advice of other native plant enthusiasts in the area, www.mdflora.org and displaying at local events with an MNPS table. She is planning a canoe trip at Anita C. P.O. Box 4877 Silver Spring, MD 20914 Light Estuary in August and a trip to serpentine barrens in early October. Many of her contacts hat a wonderful plant!
