When flowers are chewed they produce a peppery sensation on the tongue. Var. medium is distinguished from var. virginicum by a hairless inflorescence and a slightly flattened pedicel, while var. virginicum has a hairy inflorescence and a round pedicle.
Seeds require light to germinate (Toole and Toole 1940). Gibberellic acid enabled these seeds to germinate in darkness.
Martin et al. (1951) report that both Canada geese and white-tail deer eat the foliage of pepperweed.
