The Red Maple Built for Brilliant Minnesota Fall Color Red Sunset Red Maple (Acer rubrum 'Franksred') is widely considered the most reliable red maple cultivar for dependable fall color in the Upper Midwest. It grows fast, forms a clean upright-oval canopy, and adapts to a wide range of soils — including the heavier, wetter spots where many shade trees struggle. Cold-hardy to USDA zone 3, it shrugs off Minnesota winters once established. Whether you're planting a fast-growing shade tree in Maple Grove, a boulevard street tree in St. Paul, or a single brilliant lawn specimen in Edina, Red Sunset gets the job done. Red Sunset Red Maple Plant Details Attribute Detail Scientific Name Acer rubrum 'Franksred' (RED SUNSET) Common Names Red Sunset Red Maple, Red Sunset Maple, Swamp Maple Mature Height 45–60 feet Mature Width 35–45 feet Growth Rate Fast — 2–3 feet per year in Minnesota once established Sun Full sun (6+ hrs); tolerates light afternoon shade Water Moderate. Tolerates average rainfall and handles wet or poorly drained sites better than most shade trees. USDA Zones 3–9 (Twin Cities is zone 4b–5a) — exceptionally cold-hardy Soil Highly adaptable. Prefers slightly acidic, moist loam but tolerates Minnesota clay-loam and wet ground. Can show leaf yellowing (chlorosis) in very high-pH soils. Foliage Deciduous — drops in fall after a brilliant orange-red display Fall Color Reliable, brilliant orange-red — earlier and more dependable than seedling red maples Winter Hardiness Reliable well below -30°F once established — one of the hardiest shade trees we sell Deer Resistance Moderately deer-resistant; protect the trunk from buck rub the first 2 winters Native Status Red maple (Acer rubrum) is native to eastern and southeastern Minnesota and across eastern North America Red Sunset Red Maple Uses in Minnesota Landscapes Fast-Growing Shade Tree Red Sunset is one of the quickest ways to put real shade over a Twin Cities yard, adding 2–3 feet a year and forming a broad oval canopy 45–60 feet tall. It is an excellent replacement for ash trees lost to emerald ash borer, filling the gap far faster than an oak. Pair it with shade-tolerant underplantings once the canopy matures. Boulevard and Street Tree Its strong central leader, clean branching, and tolerance of compacted urban soil make Red Sunset a go-to boulevard tree in Minneapolis and St. Paul. It handles the tougher growing conditions of a street strip better than sugar maple, though it is best kept back from the heaviest road-salt spray. Brilliant Fall-Color Specimen Planted alone in a front lawn, Red Sunset becomes the centerpiece of the block every October, turning a uniform, brilliant orange-red weeks before many other maples color up. The reliable, grafted color is the whole reason this cultivar exists. Wet and Low-Lying Sites Also called swamp maple, Acer rubrum naturally grows in wet bottomlands, so Red Sunset thrives in the soggy, poorly drained corners of a property where most shade trees sulk — a useful trait for rain-garden edges and low spots in Woodbury and Maple Grove. Best Time to Plant Red Sunset Red 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. Aim to get it in the ground at least six weeks before the ground freezes — typically mid-November in the Twin Cities. Avoid mid-summer planting during heat and humidity. Hardy deciduous trees and shrubs, including balled-and-burlapped stock, plant successfully through the end of October, and in spring once the ground thaws in late April. How to Plant Red Sunset Red 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 — Red Sunset 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 25–35 feet of clearance from buildings and other large trees; space a row or allee 30–40 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 Red Sunset Red 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 Red Sunset largely takes care of itself, needing supplemental water only during extended droughts (two-plus weeks with no rain and temps above 80°F). When you do water, soak deeply to 8–12 inches every 7–14 days and let natural rainfall do the rest. Will Red Sunset Red Maple survive a Minnesota winter? Yes — easily. It's rated to USDA zone 3 and is reliably hardy well below -30°F once established, making it one of the toughest shade trees for the Twin Cities. In the first winter, wrap the young trunk to prevent sunscald and buck rub. How fast does it grow here? Fast for a shade tree — about 2–3 feet per year in good Minnesota soil with adequate moisture. Growth is naturally a bit slower than in southern climates because of our shorter season, but Red Sunset is among the quickest large maples you can plant. Is it native to Minnesota? Red maple (Acer rubrum) is native to eastern and southeastern Minnesota and throughout eastern North America. 'Franksred' is a selected cultivar bred for more reliable, brilliant fall color than wild seedlings. Does it handle clay and wet soil? Yes. Red Sunset is more tolerant of heavy clay-loam and wet, poorly drained ground than most shade trees — its wild ancestor grows in swampy bottomlands. In very alkaline (high-pH) soil it can show leaf yellowing, which a slightly acidic amendment helps prevent. Can I plant it near the road or driveway? It makes a fine boulevard tree and tolerates urban soil, but keep it back from the heaviest direct road-salt spray, which red maples don't love.

How Many Red Sunset Red Maples Do I Need? Red Sunset is a full-size shade tree — one is usually enough to anchor a typical Twin Cities front yard. Give a single specimen 25–35 feet of clearance from the house, driveway, and other large trees. For a property-line row or driveway allee on acreage, space trees 30–40 feet on center (a 120-foot line takes 4 trees at 40-foot spacing). Don't crowd it — the 35–45 foot canopy needs room to develop its full oval form. Red Sunset Red Maple Season-by-Season in Minnesota Spring: Clusters of small red flowers line the bare branches in early April — among the first pollen sources for emerging native bees — followed by red-tinted samaras and fresh green leaves. Summer: A dense, broad oval canopy of clean green foliage grows 2–3 feet a year and throws real, picnic-worthy shade. Fall: The signature show — a uniform blaze of brilliant orange-red that colors up weeks before most other maples and holds for a long stretch of October. Winter: Smooth silver-gray bark and a strong, symmetrical branch structure stand out handsomely against the snow.

Red Sunset thrives in full sun and moist, slightly acidic soil, handles heavy clay and wet low spots better than nearly any other shade tree, and laughs at zone 4 winters. You need real space — plan for a 45–60 foot tree with a 35–45 foot spread, well clear of wires and foundations. It's not a fit if your yard is small, your soil is strongly alkaline (chlorosis risk), or the site takes heavy direct road-salt spray — a honeylocust or hackberry handles salt better. Show more
