Silver Maple — Acer saccharinum

Overview: Very fast-growing native shade tree with a broad crown and deeply cut, five-lobed leaves that flash silver-white undersides in the wind. Early spring flowers, abundant samaras, and strong site adaptability.

Size & habit: 50–80′ tall × 40–60′ wide (larger with age). Broad-oval canopy; long, arching branches.

Growth rate: Fast (often 2–3+ ft/yr on good sites).

Hardiness: USDA Zones 3–9.

Light: Full sun (6+ hrs/day).

Soil & water: Highly adaptable. Prefers moist, well-drained soils; tolerates periodic flooding, clay, and compacted urban soils. Handles a range of pH better than many maples. Provide moisture while establishing.

Leaves, flowers, fruit & bark:

• Leaves: Deeply lobed, medium green with bright silver undersides; fall color typically yellow (variable).

• Flowers: Small red to yellow clusters very early spring (often before leaf-out).

• Fruit: Large paired samaras maturing late spring.

• Bark: Smooth gray when young, becoming shaggy and scaly.

Tolerance / concerns:

• Pros: Rapid shade, flood tolerance, tough on difficult sites.

• Cons: Brittle wood and weak branch unions → prone to storm damage; surface roots can heave pavements; abundant seedlings; moderate sensitivity to de-icing salt. Common pests include aphids (honeydew/sooty mold) and leafhoppers; susceptible to Verticillium wilt on stressed trees.

Pruning: Prioritize early structural training—establish a single dominant leader and wide branch angles; remove codominant stems and weak, narrow crotches. Best timing mid-winter or mid-summer; avoid heavy spring cuts (sap “bleed”). Do not top.

Transplanting: Moves easily from container or B&B when young; water deeply the first 2–3 seasons.

Landscape uses: Large shade tree for expansive lawns, parks, and riparian/low sites; quick canopy for reclamation and windbreak edges. Not recommended for tight spaces, near sidewalks, or beneath overhead lines.

Spacing / clearance: Plant 35–50 ft from buildings; keep 10–12 ft from pavements; avoid conflicts with overhead utilities and keep well away from septic fields and drain tiles.
