Broom

A possible alternate to Reed is Scotch Broom.

BroomThe broom is native to Great Britain and grows in abundance along the heaths, moors, and in open spaces.  It is a small tree, rarely growing above 7 feet tall, and is thick and bushy.  Its stems are long, thin, and green.  From them sprout an abundance of pod-shaped yellow flowers, which bloom in the summer.  The broom is closely related to the gorse bush. 

Broom shares the Ogham letter Ngetal with Reed.  Broom is useful in "cleaning up" spiritual or mental messes.  It is used to correct or heal damage or injury.  For instance, if you are having negative thoughts, emotions, or actions, use the broom to help you get rid of them.  Think of this tree as the herald of new beginnings.   
On the mundane level the broom has many uses.  One obvious use is in making a besom.  A decoction of broom is useful for gout, sciatica, painful joints, malaria, and fever.  Use with care.  Too large a dose can cause extreme bouts of vomiting.
