Aspen (Populus tremuloides)

The quaking aspen looks best in forest or grove plantings where its Fall colors are multiplied. Specimens being collected transplant best before they leaf out. Trees in leaf have a very poor chance of survival. Controlled drought-stress brings about earlier Fall colors. Some of the faults of these trees as bonsai which some have mentioned: disease-prone, subject to insect infestations, short-lived, and can shed branches at random intervals. Protecting aspen from hard freezes is said to prevent lower branch die-back.
