Hawthorn (also frequently called Whitethorn) is very common and can be found almost everywhere in the countryside. It is regularly used for fencing because it becomes almost impenetrable when kept clipped.
While the bark of the hawthorn is a featureless dark green, its heartwood is a nice reddish brown. Because of this, most of my Hawthorn sticks are de-barked before finishing.
Hawthorn makes good quality walking sticks which are attractive, strong and long lasting.
