The moss Scott is growing – on a small dessert plate – was taken from a rock in Crum Creek. “It was already coming loose from the rock,” Scott promises. He is looking for the best species of moss to cover one wall of the first-floor bathroom of his home at the corner of Dartmouth and Amherst – the Detweiler house, as many in Swarthmore know it. Scott envisions the moss absorbing the room’s excess moisture and giving off oxygen. “What a great way to start the day,” he predicts.
