Aspen

The Aspen Tree is a fast-growing deciduous tree admired for its fluttering, round leaves and smooth white bark. Known for forming colonies through underground roots, it creates stunning fall displays of golden yellow.
Populus Tremuloides (Quaking Aspen)
Origin: North America
USDA Hardiness Zones: 2-7
Pros:
Beautiful fall color – brilliant golden foliage in autumn
Colony-forming – spreads by root suckers to create natural groves and thickets
Cons:
Aggressive spreader – underground roots send up new shoots far from the original tree
Short-lived & pest-prone – often lives only 20–50 years and is vulnerable to cankers, borers, and leaf spots
