Alder is the third letter in the Gaelic tree alphabet (though in some versions it’s the fifth). It is a symbol of secrecy and a place for trysting. It loves wet, dark, spooky places. It is also known as the shield tree? One old Scottish tradition was to plant alder stakes around the grave of a childless woman, to shield the community from her bad luck.
under the alder
a graveyard of roots grumbling
an ooze of wet yesterdays
a seep of longing
a wall of abandoned paintings
a secret hoard
a burying beetle
a heart looking for a shield
a world inside a ball of dung
a universe inside a blinking plankton
a canopy of clouds
a sea of darkness
a time, a place
an old woman cooking for one
a sad song (under the alder) waiting to be sung
