The rowan (mountain ash) is a ubiquitous bush to medium sized tree found throughout Europe and eastern North America. It even occurs west of the Mississippi. An important winter/spring food source for small wildlife, especially birds, it has some uses for human foragers, too. Among other things, its berries make a wonderful bitter-tart jelly or sauce that is excellent on red meat.
