Seven predictions (#263-269) for flower colour, transparency, bioluminescence, acoustic resonance, and longevity from OHC Bessel geometry. Blue-banded bees sonicate at 350 Hz — the OHC fundamental. This frequency selects for blue flowers. Skeleton flower transparency arises from n = 4/3. Dedicated to Jules. Zero free parameters. Three inputs. One geometry.
