This is the only species of dogwood in the United States. It is found in nearly every state of the Union, and is from twenty to thirty feet high. It has a diameter of from ten to twelve inches. The wood is hard, strong, heavy, has a very fine grain, and is used for small panel work, and for almost anything where it is necessary to give a high polish. The flowers are small and form in clusters, surrounded by four large white leaves. It also bears a red berry, which forms a pleasant contrast to the large white leaves, and makes the dogwood one of our most ornamental trees. The seeds of the dogwood require from two to three years to make them vegetate, but Michaux gives the f ollowing method: Gather the seeds in the fall, clear them of their pulpy covering by rubbing them in water, cover them with earth in a box, and place them in the cellar till spring, care being taken to keep the earth moist.
