The low shrubs known as New Jersey Tea, belonging to the Genus Ceanothus, were once very abundant throughout Iowa, occurring chiefly on the prairies, and sometimes in dry, open woods and along the borders of drier thickets. On account of their long, tough roots they interfered with the breaking of the prairie, and the commoner species, C. americanus, known as "shoestring" or "red-root," was by no means popular with the pioneers. Perhaps for this reason, and because they were so common, these attractive shrubs were seldom cultivated in this state.
