It offers sculptural shaggy bark, fine-textured foliage that turns yellow to bronze in fall, and hop-like seed clusters that hang on through winter for birds and beauty alike — all on a slow-growing, long-lived tree with famously hard wood. Exceptionally shade-tolerant and unfazed by clay, drought, or deep cold, it's a dependable choice for a shady Edina yard, a naturalized Woodbury woodland edge, or a tough boulevard in Plymouth.\u003c\/p\u003e\n\u003ch2\u003eIronwood Plant Details\u003c\/h2\u003e\n\u003ctable cellpadding=\"6\" border=\"1\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAttribute\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eDetail\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eScientific Name\u003c\/td\u003e\n\u003ctd\u003eOstrya virginiana\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Names\u003c\/td\u003e\n\u003ctd\u003eIronwood, American Hophornbeam, Hophornbeam\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMature Height\u003c\/td\u003e\n\u003ctd\u003e25-40 feet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMature Width\u003c\/td\u003e\n\u003ctd\u003e20-30 feet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGrowth Rate\u003c\/td\u003e\n\u003ctd\u003eSlow\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSun\u003c\/td\u003e\n\u003ctd\u003eFull sun to part shade (excellent shade tolerance)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater\u003c\/td\u003e\n\u003ctd\u003eModerate; drought-tolerant once established\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUSDA Zones\u003c\/td\u003e\n\u003ctd\u003e3-9 (Twin Cities is zone 4b-5a)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSoil\u003c\/td\u003e\n\u003ctd\u003eHighly adaptable; prefers well-drained loam, tolerates clay and dry sites\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFoliage\u003c\/td\u003e\n\u003ctd\u003eDeciduous; fine-textured, yellow to bronze fall color\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBark \u0026amp; Fruit\u003c\/td\u003e\n\u003ctd\u003eShaggy, sculptural bark; hop-like seed clusters persist into winter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWinter Hardiness\u003c\/td\u003e\n\u003ctd\u003eReliable to -40F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDeer Resistance\u003c\/td\u003e\n\u003ctd\u003eGood; rarely a deer favorite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNative Status\u003c\/td\u003e\n\u003ctd\u003eMinnesota native\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eIronwood Uses in Minnesota Landscapes\u003c\/h2\u003e\n\u003ch3\u003eNative Understory and Woodland Shade Tree\u003c\/h3\u003e\n\u003cp\u003eIronwood naturally grows beneath taller oaks and maples, which makes it one of the most shade-tolerant trees we carry. It's ideal for layering a woodland edge, filling a shady corner, or adding a native mid-story to an established yard in Minneapolis or St. Paul where sun-loving trees simply won't thrive. For native and restoration plantings, it's a quiet workhorse.\u003c\/p\u003e\n\u003ch3\u003eTough, Low-Maintenance Specimen\u003c\/h3\u003e\n\u003cp\u003eOnce established, Ironwood shrugs off drought, clay, dry soil, and harsh exposure — the same durability that gives its wood the \"iron\" name. It's slow-growing and long-lived, asking almost nothing in return, so it's a smart pick for a low-care lawn tree or a difficult dry site in Eden Prairie or Maple Grove that has defeated softer trees.\u003c\/p\u003e\n\u003ch3\u003eWildlife and Four-Season Interest\u003c\/h3\u003e\n\u003cp\u003eThe shaggy, sculptural bark and the papery hop-like seed clusters give Ironwood real winter character, and those clusters feed finches, grouse, and other birds through the cold months.

Spring planting allows a full season to establish; fall planting uses warm soil and cool air for strong rooting. Avoid the heat of midsummer when possible, and don't plant after mid-October, when frozen ground can heave new roots. Note that slow-growing Ironwood appreciates patience after transplanting.\u003c\/p\u003e\n\u003ch2\u003eHow to Plant Ironwood\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eDig wide, not deep.\u003c\/strong\u003e Make the hole 2 to 3 times the width of the root ball but no deeper — the root flare should sit slightly above grade.

During prolonged dry spells (two-plus weeks without rain), give it a deep soak every 10 to 14 days; otherwise let Minnesota's rainfall do the work. Its low-water toughness after establishment is a big part of its appeal.\u003c\/p\u003e\n\u003ch3\u003eWill Ironwood survive a Minnesota winter?\u003c\/h3\u003e\n\u003cp\u003eEasily — it's hardy to roughly -40°F (USDA zone 3), far below anything the Twin Cities' zone 4b–5a delivers, and as a local native it's perfectly adapted to our winters. The persistent hop clusters and shaggy bark even make it more interesting in winter. No special protection is needed once established.\u003c\/p\u003e\n\u003ch3\u003eIs it deer-resistant?\u003c\/h3\u003e\n\u003cp\u003eGenerally yes. Ironwood is rarely a deer favorite, so it holds up better than most young trees in high-pressure western suburbs like Minnetonka and Wayzata. A trunk guard is still wise the first winter or two to prevent buck rub, but heavy browse is uncommon.\u003c\/p\u003e\n\u003ch3\u003eHow shade-tolerant is it?\u003c\/h3\u003e\n\u003cp\u003eAmong the most of any tree we sell. Ironwood evolved as an understory species beneath taller hardwoods, so it grows well in part to fairly deep shade where other trees fail — while still performing in full sun. That flexibility makes it invaluable for shady, established yards.\u003c\/p\u003e\n\u003ch3\u003eWhy is it called Ironwood, and how fast does it grow?\u003c\/h3\u003e\n\u003cp\u003eThe name comes from its exceptionally hard, dense wood. That toughness comes with slow growth — Ironwood takes its time, which is why it's so long-lived and durable. If you want quicker height, start with a larger caliper tree; if you want a tree that will outlast you with little fuss, this is it.\u003c\/p\u003e\n\u003ch2\u003eYou May Also Like\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutumn Treasure Ironwood\u003c\/strong\u003e — an improved selection with a more uniform crown and brighter gold fall color.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKentucky Coffeetree\u003c\/strong\u003e — a bold native shade tree with dramatic winter branch structure for larger spaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNannyberry Viburnum\u003c\/strong\u003e — a native small specimen tree with spring flowers, bird berries, and burgundy fall color.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrairie Dream Birch\u003c\/strong\u003e — a hardy white-barked native birch for bright winter bark and bird value.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!-- tt-enriched --\u003e\n\u003ch2\u003eHow Many Ironwood Do I Need?\u003c\/h2\u003e\n\u003cp\u003eIronwood works as a single understory specimen or in small naturalized groves.
