POPLARS

  • two main groups - willows, poplars and aspens
  • broad-leaved trees grow extremely fast, are short lives
  • seeds are adapted for wind dispersal, have tuft of white hairs enabling them to be blown
  • North American quaking aspens can survive drought and flooding
  • leaves shake and tremble even when there is no detectable wind - leaf stems are long and on right angles
  • male's have about 50 separate flowers, look like a cup holding a stem - are dark red then change to yellow from pollen
  • female's are larger than male with a similar amount of flowers, ripen to form seed pods and split in midsummer to release seeds
