Meadow Foxtail is not a foxtail at all. It has a seed head similar to timothy but is much smaller. Normally found in the northern part of the state it is not a serious problem except in some nurseries. A related plant, blackgrass (Alopecurus myosuroides), is a serious weed problem in some states but is not yet present in New Jersey.
