Wallflower, Or Gilliflower. There has been a curious confusion with respect to the clove-pink and the wallflower. The former belongs to the natural order Caryophyllce. the latter to Cruciferce. The clove-pink (not the cultivated double flower of the garden) grows upon old walls and ruins, as at Norwich, and on the castles of Deal, Sandown, and Rochester, flowering in July; hence it was said to be a "wallflower," and a " July-flower." Chaucer calls it " clove-gilofre," or, " clove-gilli-fiower." Thus the clove-pink, Dianthus caryophyllus, came to be named " gilli-flower" (July-flower), and "wallflower." The true wallflower belongs to the same tribe of plants as the stock, mustard, cress, etc, which have their petals arranged in the form of a cross, and hence named Cruciferce (cross-bearers). It grows on old walls, and begins flowering in April, having a delicious scent. It has been improperly called "gilli-flower," and "sweet-william," neither of which it resembles.
