"Monarch way stations"

After reading this recent feature about monarch butterflies (NYT; 3 October 2006; byline Donald G. McNeil, Jr.), we're happy to see more milkweed seeds germinating and many of those that survived the summer now showing a spurt of growth and reinvigoration, with some blooming for the first time. At least a couple are the handsome orange-and-yellow version that is more susceptible to killing frosts (the majority are the sturdier all-yellow ones).
