I live about a mile from the boundary of the Southern Appalachian and Ridge & Valley geological/eco systems, and at least once a week drive over the "border," almost perfectly demarcated by Mabe Stanleytown Road, which follows a stream valley. It's fun to see the changes (and similarities) in flora - different Hexastylis, Trillium and Asplenium species grow up the mountains on opposite sides of the road, and their hybrids grow in the floodplain where the basic and acidic soils mix. A friend who lives off Mabe Stanleytown heard from a neighbor that rattlesnakes live on one side of the road, and copperheads on the other. I'll take rattlesnakes any day! -joe, Scott Co., VA z6b confused by a z8b winter. _______________________________________________ pbs mailing list pbs@lists.pacificbulbsociety.net http://lists.pacificbulbsociety.net/cgi-bin/…
