Dahlia Roots Edible?—According to the Scientific American the dahlia was originally grown in Europe for its roots which were used as food. Roasted they are said to be both toothsome and wholesome. Further observations along this line would be desirable.

Edible Arums.The Gardening World, referring to a recent note in this journal regarding the edible qualities of the elephant's ear (Caladium esculentum) a member of the arum family, notes that an English species Arum Italicum known as Portland sago has been used as food. Both these species are regarded as more or less poisonous in the raw state, but cooking drives out the noxious qualities. The arum family contains numerous plants of importance to man, some being used for food or medicine and others valued for their striking flowers. The skunk's cabbage, jack-in-the-pulpit and green dragon belong to this family and so does the sweet flag or calamus-root (Acorus calamus). It is reported that the American Indian formerly made great use of the seeds of the golden club (Oronticum aquaticum) boiling and eating them as we do peas. Certain lakes in the Eastern States are thickly bordered with these plants which it is believed were originally planted there by the Aborigines.
