Soft corrugations in the boortree’s trunk,
Its green young shoots, its rods like freckled solder:
It was our bower as children, a greenish, dank
And snapping memory as I get older.
And elderberry I have learned to call it.
I love its blooms like saucers brimmed with meal,
Its berries a swart caviar of shot,
A buoyant spawn, a light bruised out of purple.
Elderberry? It is shires dreaming wine.
Boortree is bower tree, where I played ‘touching tongues’
And felt another’s texture quick on mine.
So, etymologist of roots and graftings,
I fall back to my tree-house and would crouch
Where small buds shoot and flourish in the hush.
