Nastic Valentine

Where the horizon
of this flower
goes at night
is it closure
of a muscular
kind or a pre-
nerve empathic
death of molecules
resulting in a slow
pivot of petals
a corps de ballet
as night leaps
onto the stage
the audience gasps
the horizon folds up
into its original dark
stitch and itch
a vertical line
I guess which the
dance unwinds.
