Sycamore maple (Acer pseudoplatanus)

Introduction

  • Most maples trees grow to 45 m/148 ft and live for 400 years.
  • Most species are deciduous, but a few in southern Asia and the Mediterranean region are evergreen.
  • Palm shaped (palmate) leaves measure 7-16 cm and have five lobes .
  • The distinctive fruits are called samaras (also known as maple keys, helicopters, whirlybirds, polynoses).
  • The fruits occur in distinctive pairs, each containing a seed attached to a wing; they are shaped to spin as they fall which carry the seeds a considerable distance on the wind.
  • Seeds mature in a few weeks to six months after flowering; seeds disperse shortly after maturity.
  • One tree can release hundreds of thousands of seeds at a time.
  • Not to be confused with the Norway maple (Acer plantanoides) or field maple (Acer campestre) that do not present a risk as they do not produce hypoglycin.
