Shirley and Lee, Re. Cosmos atrosanguineus, Appropriately, the first place where I collected seed of this Cosmos was in meadows of herbs under tall pines on a hillside in Jalisco, Mexico. I believe, in my field notes I remarked how the site reminded me of the pine woods of Pebble Beach and the Monterey Peninsula. They have a good home with you Shirley. Another geophytic Cosmos which I once collected and grew at the Huntington, but which we lost, was C. seemannii. This was a small grower with almost dahlia-like tubers. As I recall it was from well drained slopes. Leaves were very divided and fern-like. I don't recall if it was fragrant. Fred Boutin Tuolumne, CA
