Allium perdulce var. sperryi is a well-marked, polyploiid, geographic variant. Although both varieties of the species reach the same extremes of size, var. sperryi is, on average, considerably taller and stouter than var. perdulce. It also tends to have a larger number of flowers and longer pedicels. Distributions of the two varieties do not overlap.
