Populus hosts caterpillars of 367 species
of butterflies and moths, in some areas.   This plant is also known to be a host for (in areas where invasive) 🐝︎ spotted lanternfly (SLF)  Lycorma delicatula.

Can form a hybrid with balsam poplar  Populus balsamifera (also part of the aspen/cottonwood/poplar  genus Populus ), forming balm of Gilead  Populus × jackii.   The hybrid occurs occasionally in nature.

Often grows in clonal colonies [1] —look around for other stems!
