Teazles

Out in the vacant lot to gather weeds
I found these teazles – their ovoid heads
delicately armoured with crowns of thorns.
Arthur, from whom I haven’t heard a word
in thirty years, who must be ninety if
he’s a day, told me they were used to raise
the nap on the green felt of billiards tables
and, since Roman times, for combing woollen stuff.
He also said their seeds were caviar
to the goldfinch. And then I lost the knife
he’d lent me to cut some – the loss of which
was the cause of grief. In honour of gruff Arthur
I shake the seeds out in our small green patch
and stick the spiky seed heads in a jar.
