Description:
  • small- to medium-sized deciduous tree
  • etymology: Acer is the classical name; Acer means sharp, probably from Roman spears with sharp tips, made from the wood of a maple species; negundo from resemblance to leaves of Vitex negundo (chastetree)
  • leaf compound (unusual for a maple), with 3-5 (7) leaflets; also called ash-leaved maple
  • dioecious (separate male and female trees); flowers small, lacking petals
  • fruit = 2 joined samaras (winged achenes)
  • wood soft; used to make cheap furniture and boxes, hence the common name “box-elder”; but not related to true elders (Sambucus)
  • native habitat moist soils; does well in sun or shade, wet or dry soils
