Cedar Elm
Ulmus crassifoliaAlso known as Texas Cedar Elm, Southern Rock Elm, Basket Elm, Olmo
Cedar elms dominate river valleys and limestone ridges across Texas and neighboring states, earning renown as exceptionally hardy shade trees. Unlike most North American elms that bloom in early spring, this species flowers and disperses winged seeds in late summer and autumn. Twigs frequently develop corky, wing-like ridges that complement its stiff, sandpaper-textured foliage.
