Concepts

DOGWOOD NAME

  1. Where did the dogwood get its unique name?
  2. Long ago, it was also called 'Hound's Tree,' and its fruits 'dogberries' or 'houndberries.'
  3. One theory is that the tree was originally named 'dagwood,' because its sticks were used to make dags (daggers or sharpened rods).
  4. It may be that dagwood turned into dogwood around 1548.

An additional name for the dogwood long ago was 'whippletree.'

Recite aloud Geoffrey Chaucer's 'The Knights Tale' verse 2065, which refers to the whippletree.

  1. Maple, thorn, beech, hazel, yew, whipple tree,
  2. How they were felled, shall not be told for me;
