LSA English professor Cody Walker’s rhythmic poem “A Mad Gardener’s Murmur” is an example of what type of formal verse?
A ballad
Correct. More specifically, Walker’s ballad (a pastiche of Lewis Caroll) is a set of six sestets written in common meter, or alternating iambic tetrameter and iambic trimeter . . . but you probably don’t need to know that.
