Adenophora
(from aden, a gland, and phoreo, to bear; in reference to the cylindrical nectary which girds the base of the style). ORD. Campanulaceae. A genus of elegant hardy border perennials, very similar in habit, shape of flower, &c., to Campanula, from which genus Adenophora differs in having the style surrounded by a cylindrical gland. Flowers stalked, drooping, spicate. Leaves broad, stalked, somewhat whorled. They grow best in light rich garden soil, with a warm sunny position, and should be increased by seeds, as dividing the roots is the sure way to lose them. They are easily raised from seeds, which may be sown as soon as ripe, or in spring, in pots placed in a cold frame.
