to me the fact that they are of one clone doesn't address the mystery.
how does the plant know? what is the trigger, given that it can't be,
say, the 15th spring if plants are blooming at the same time in the
northern and southern hemisphere? to me, it's an extreme example of a
more common mystery. many plants continue to flower in the spring of
their country of origin even when moved to the opposite hemishere.

even when they are grown from seed and even, in many cases, when the
seed has been dormant for years. how can a seed keep track of time?
