Landscape covers annuals, perennials, trees, shrubs and lawn.
CAT Alerts are also available for reading in many MSU Extension offices. For office locations and availability of paper copies of CAT Alerts, call your county's MSU Extension.

They are about 4 feet high and 4 feet across with a flat top.
