Ripeness is not “ready for eating,” no matter what the dictionaries say. Neither is it “mature.” Have a look.
One definition is “sensuous and full”, as in “ripe lips,” and another “emitting a foul odour,” and another “vulgar.” None of these are ripeness, as they all have to do with eating. A better definition would be “full” of “completeness,” or “embodying its full opening before retraction in preparation for another opening.” This wavy-leaved thistle, for instance, will close up, and grow a flower stalk next year, in a two year cycle, before giving this fullness over to seed to open again.
Ripeness is a fullness of rhythm. It is the point where everything is potential.
It doesn’t come in spring. That is only the first hint of potential’s power to open.
