in the Thirteenth Century
discovered mathematically precise
progressions and went on to theorise
that zero, one and one and two and three
would show how rabbits breeding in a field
might multiply. Seven centuries went by,
then Turing in his garden one day spied
these self-same forms in sunflowers so revealed.
Such beauty and precision may be found
in ferns and fir-cones, flowers and all around
on land and sea – a golden ratio.
And yet for all this symmetry, we know
that sometimes flowers, like men, refuse to fit
our expectations and are finer for it.
