How do different plants of the same kind know to bloom all at the same time,

no matter at what stage of development they happen to be? This happens regardless of whether plants are in close proximity and subject to direct communication through pollen exchange or something similar. There must be some kind of genetic memory intrinsic to organic reproduction. If a plant that I’ve transplanted loses leaves so that it’s out of balance, it’ll shut back, still producing new leaves and branches, but keeping them very close to the trunk, lest it accelerate its own demise. There may be more to Platonic forms than verbal plateaus, something like visual programming.
