wallflower A woman who does not join in the festivities at a dance or ball, either by choice or because she does not have a partner; by stereotypic implication, a shy or homely woman. In the world of plants, the wallflower (Cheiranthus cheiri) is a yellow or orange flower that grows on old walls and buildings. According to a legend recounted by the English poet Robert Herrick (1591-1674), a woman who had long been kept in captivity tried to reach her lover by climbing down a steep wall, but slipped and died. Herrick continues:

Love, in pity of the deed,
And her loving luckless speed,
Turned her to this plant we call Now the “flower of the wall.”

Thus, a girl or woman who sits along a wall at a dance is sometimes called a “wallflower,” likening her to the blossom of the same name.

[He] dances quadrilles with every wallflower in the room. (New Monthly Magazine, 1840)
