A gardener named Derek Ellis
decided to erect a trellis
to train his Runner Beans around
to save them lying on the ground.

He popped down to the garden store
where they had trellis by the score
and chose one with diagonal squares
intended for espalier pears.

His beans now grow in chevrons neat
(for Runner Beans, that’s quite a feat)
They grow dead straight to uniform sizes
and are always winning Derek prizes
