Eastern Cottonwood
Scientific Name: Populus deltoides
Plant Family: Salicaceae
Native Region: Central and eastern North America
Brief Description
A fast-growing, large deciduous tree known for its massive trunk, deeply furrowed gray bark, and triangular (deltoid) leaves that shimmer and rustle in the breeze.
Care Instructions
Requires full sun and ample space. Exceptionally water-demanding; thrives near riparian zones but tolerates urban settings if soil is kept moist during establishment. Minimal pruning needed except to remove brittle, fallen branches.
Medicinal Value
We do not currently provide medicinal value for plant identifications.
Sunlight
Full sun, requiring at least 6 to 8 hours of direct sunlight per day.
Watering
High water needs; prefers consistently moist soil but can tolerate occasional flooding. Drought can lead to early leaf drop.
Soil
Rich, moist, well-drained soils; adaptable to various pH levels but prefers slightly acidic to neutral (5.0-7.5).
Hardiness Zone
2 to 9
Growth Habit
Perennial tree; fast-growing (up to 6 feet per year) reaching 75-100 feet tall with a wide, spreading canopy.
Bloom Season
Spring (March to April); produces catkins before leaves emerge. Female trees produce 'cotton' seeds in early summer.
Toxicity
Low toxicity; however, the pollen is a significant allergen for humans. Horses may experience digestive issues if they consume large amounts of bark.
Propagation
Easily propagated through hardwood cuttings in winter or by seed (fresh seeds must be sown immediately).
Common Pests & Issues
Subject to leaf rust, cankers, and aphids. Known for brittle wood that breaks easily in wind or ice storms (hazard tree near structures).
Similar Species
Quaking Aspen (shorter, smoother bark) and Silver Poplar (white underside of leaves). Cottonwood leaves are larger and strictly triangular.
Interesting Facts
The 'cotton' seen in summer consists of seed hairs that help the seeds travel on the wind. It is the state tree of Kansas, Nebraska, and Wyoming.
