There is some reason to hope that these elms will preserve the genetic diversity of the original population, and that they eventually will hybridize with DED-resistant varieties that have been developed or that occur naturally. These efforts have largely been successful in saving the majority of the trees, although several are still lost each year. Young and medium-aged trees can still be found in the The trees are particularly noteworthy along the Mall and Literary Walk, where four lines of American elms stretch over the walkway forming a cathedral-like covering.

Croix', and a set of six different clones collectively known as 'American Liberty'. En savoir plus sur les navigateurs que nous supportons. [9] Ohio botanist William B. Werthner, discussing the contrast between open-grown and forest-grown American elms, noted that: In the open, with an abundance of air and light, the main trunk divides into several leading branches which leave the trunk at a sharp angle and continue to grow upward, gradually diverging, dividing and subdividing into long, flexible branchlets whose ends, at last, float lightly in the air, giving the tree a round, somewhat flattened top of beautifully regular proportions and characteristically fine twiggery.[9]. As in the closely related European White Elm Ulmus laevis, the flowers and seeds are borne on 1–3 cm long stems. Older trees sometimes develop buttresses that expand their base.
