Native from Labrador
to Alaska, south to Pennsylvania, Missouri, northern Mexico and California,
this species is the most widely-distributed North American tree. It is common
in eastern Iowa and found scattered along principal river valleys in southern
and western Iowa. The slender, vertically flattened leaf stalks cause the
"quaking" or "trembling" motion that gives the tree
its common names. Although this is an ornamental tree, it is not well suited
to landscaping. Root suckers form dense thickets unless controlled; the
crown produces very little shade; it is prone to pests and diseases; and
the shallow roots extend far from the trunk. |
