The flowering season begins in early spring, and a huge number of seeds are produced every year. Box elder is widespread all over the world, its prevalence is observed in some parts of the USA, Europe, Canada, Asia, China, Mexico and Guatemala.

Exposure to its pollen can cause allergic respiratory symptoms such as asthma, allergic rhinitis and rhinoconjunctivitis. Analysis have revealed a link between increased concentrations of tree pollen (boxwood elder and maple pollen) and high rates of hospitalization due to severe asthma.
To date, no allergens have been identified; however, several potentially allergenic protein bands have been reported. Cross-reactivity has been found to be high with maples, walnuts and limited to pollen from other trees such as American plane tree, poplar, birch, petiolate oak and weeping willow.
