Bulletin of the American Rock Garden Society VOL. 47 WINTER 1989 NO. 1 Foreword This issue of the Bulletin has a number of changes which are worth mentioning. The size is slightly different, which comes from being printed on a small web press. The efficiencies gained by this process have allowed us to add 16 pages to the Bulletin. In addition, we have re- introduced color to the inside providing an additional 4 pages. We hope you like this expansion. Editorially, you will find three pieces on the Pine Barrens which will be an important part of the schedule for this summer's annual meeting in Wilmington, DE. The spring issue will include articles on native plants at Mt. Cuba Center and the Rock Garden at Winterthur, both scheduled for tours during the annual meeting. We hope these whet your appetite for this well-planned event. We have gone farther afield, too. In addition to articles from both coasts and points between, you will find a discussion of seed germina• tion by a seedsman from Germany and an introduction to the terrestrial Calanthe Orchids of Japan. And one man's personal viewpoint of rock gardening through the year begins with this issue — as Geoffrey Char- lesworth looks at the Rock Garden in Winter.
