Globular blue-daisy: A genus of the monogyne order, belonging to the tetrantha clasps of plants; and in the natural method ranking under the 48th order, Aggregata. The common calyx is imbricated; the proper one tubulated inferior; the upper lip of the florets bipartite, the under one triplicate; the receptacle paleaceous. There are several species; but only one is commonly to be met with in our gardens, viz. the vulgaris, or common blue daisy. It hath broad thick radical leaves three parted at the ends, upright stalks from about six to ten or twelve inches high garnished with spear-shaped leaves, and the top crowned by a globular head of fine blue flowers composed of many florets in one cup. It flowers in June, and makes a good appearance; but thrives best in a moist shady situation. It is propagated by parting the roots in September.
