A University of Minnesota Maple Bred for Fast Growth and Fiery Fall Firefall Maple (Acer × freemanii 'Firefall') is a University of Minnesota introduction — a Freeman maple (red maple × silver maple) selected for fast growth, a tidy upright-oval crown, and brilliant red-orange fall color. Best of all, it's a seedless male clone, so there's no messy seed cleanup. Bred right here for our climate, it's reliably hardy to USDA zone 3. Whether you want quick shade over a Burnsville backyard, a clean boulevard tree in St. Paul, or a bold fall-color specimen in Eden Prairie, Firefall combines speed, toughness, and a spectacular autumn show. Firefall Maple Plant Details Attribute Detail Scientific Name Acer × freemanii 'Firefall' Common Names Firefall Maple, Freeman Maple, Hybrid Maple Mature Height 40–50 feet Mature Width 30–35 feet Growth Rate Fast — about 2–3 feet per year in Minnesota once established Sun Full sun (6+ hrs); tolerates light shade Water Moderate. Tolerates average rainfall and handles wetter sites well, like its red and silver maple parents. USDA Zones 3–7 (Twin Cities is zone 4b–5a) — exceptionally cold-hardy Soil Highly adaptable. Tolerates Minnesota clay-loam and wet ground; prefers moist, slightly acidic loam. Can show leaf yellowing in very high-pH soils. Foliage Deciduous — classic maple leaves; seedless (no messy samaras) Fall Color Brilliant red-orange Winter Hardiness Reliable to USDA zone 3 — bred at the U of M for the Upper Midwest Deer Resistance Moderately deer-resistant; protect the trunk from buck rub the first 2 winters Native Status A hybrid of native red maple and native silver maple; 'Firefall' is a University of Minnesota selection Firefall Maple Uses in Minnesota Landscapes Fast Shade Tree Like other Freeman maples, Firefall grows quickly — 2–3 feet a year — making it one of the fastest ways to put real shade over a Twin Cities yard. It's an excellent, quick-establishing replacement for ash trees lost to emerald ash borer. Clean, Seedless Specimen and Boulevard Tree Because Firefall is a seedless male selection, it skips the messy seed drop of silver maples and seedling red maples — a real plus over patios, drives, and boulevards. Its strong upright-oval form lines a street cleanly. Brilliant Fall-Color Focal Point The reliable red-orange fall display makes Firefall a standout lawn specimen, lighting up in October weeks of dependable color thanks to its grafted consistency. Wet and Low-Lying Sites With both red and silver maple in its parentage, Firefall tolerates the soggy, poorly drained corners of a property better than most shade trees — handy for low spots and rain-garden edges. Best Time to Plant Firefall Maple in Minnesota Plant in spring (late April–May, after the ground thaws) for a full growing season of root establishment, or in early fall (late August–early October) while the soil is still warm. Get it in the ground at least six weeks before the ground freezes — typically mid-November in the Twin Cities. Avoid mid-summer planting in heat and humidity, and never plant after mid-October or before spring thaw. How to Plant Firefall Maple Dig wide, not deep — 2–3x the root ball width but only as deep as the ball is tall, so the root flare sits at or slightly above grade. Check drainage — Firefall tolerates wet soil, but if water pools and never drains, break through any clay hardpan or mound-plant slightly. Backfill with the native soil mixed with 20–30% compost; don't create a pure-compost "container" the roots won't leave. Spacing — give a single specimen 25–30 feet of clearance; space a row or allee 30–35 feet apart. Build a 3–4 inch watering ring to direct water to the roots, then flatten it before winter so it doesn't trap ice. Mulch with 2–3 inches of shredded bark or wood chips in a wide ring, kept 2 inches off the trunk. Never use gravel mulch in Minnesota — it doesn't insulate roots. Watering Firefall Maple in Minnesota First Year Watering Schedule Weeks 1–2: water deeply and slowly every 1–2 days. Month 1–2: every 3–4 days. Month 3–6: every 5–7 days during active growth, easing off when rainfall is adequate (the Twin Cities average about 3 inches a month from June through August). Stop watering 2–3 weeks before the ground freezes — usually late October — so the tree doesn't push tender growth heading into winter. After Year One An established Firefall largely cares for itself, needing supplemental water only during extended droughts (two-plus weeks with no rain and temps above 80°F). Soak deeply to 8–12 inches every 7–14 days during dry spells and let natural rainfall do the rest. Will Firefall Maple survive a Minnesota winter? Yes — better than most. It's rated to USDA zone 3 and was bred at the University of Minnesota for our cold winters. Wrap the young trunk the first winter to prevent sunscald and buck rub. How fast does it grow here? Fast — about 2–3 feet per year in good Minnesota soil, one of the quicker large maples you can plant. Does it make a mess of seeds? No. Firefall is a seedless male selection, so it skips the heavy samara (helicopter) drop of silver maples and many red maples — a big plus near patios and drives. Is it native to Minnesota? It's a hybrid of two natives — red maple and silver maple — selected at the University of Minnesota. It carries the toughness and wet-soil tolerance of both parents. Does it handle clay and wet soil? Yes — very well. Both parent species grow in heavy, wet ground, so Firefall tolerates clay-loam and low, soggy spots better than most shade trees.

Firefall is a large shade tree, so one specimen anchors a typical Twin Cities yard. Give a single tree 25–30 feet of clearance from your house, garage, and other large trees so its 30–35-foot crown develops evenly. Lining a driveway or property edge? Plant a row at 30–35 feet on center. For faster visual impact on acreage, group three in a loose triangle 30 feet apart. Firefall Maple Season-by-Season in Minnesota Spring: Small red flowers tint the bare branches in early April, then clean green foliage leafs out quickly — and because it's a seedless male, there's no helicopter-samara drop afterward. Summer: Fast-growing upright-oval canopy adds 2–3 feet a year and casts dense, cooling shade; foliage stays clean even in wet, heavy soils. Fall: Brilliant red-orange color, dependable every October thanks to its grafted consistency — among the most vivid Freeman maples for zone 4. Winter: Tidy upright-oval silhouette with smooth gray young bark; U of M zone-3 breeding shrugs off the coldest Twin Cities winters.

Is Firefall Maple Right for Your Yard? Choose Firefall if you want fast shade and reliable red-orange fall color in full sun — it thrives in average to wet soils, tolerates clay, and is one of the best EAB-era ash replacements for zone 4. It's not a fit if your soil is very high-pH (chlorosis risk) or you're planting a tight urban courtyard — this tree needs room for a 40–50-foot canopy.
