Growth is the quietest form of change. It does not announce itself with sound or event. It does not arrive on a date you can mark. It accumulates — a fraction today, a fraction tomorrow, a fraction through weeks of weather you experience but do not connect to the shrub's progress. By the time growth becomes visible in the sense of "something is different," it has already been underway for longer than you imagine.

There is a shrub near the back fence that I have watched, intermittently, for three seasons. I say "watched," but what I mean is "walked past while thinking about other things." During that time it has roughly doubled in width. I know this because an old photograph from the first month shows a narrower plant with more visible fence behind it. The photograph is evidence of change my daily perception failed to capture.

Why is growth so easy to miss? Partly because it is continuous rather than discrete. We notice thresholds — the first flower, the first frost, the branch that finally touches the path — but not the steady approach to those thresholds. Partly because we normalize each day's version as the current truth. Yesterday's shrub and today's shrub differ slightly; the mind merges them into a single category called "the shrub" and discards the delta.

I tried an experiment: looking at the same plant at the same time each week, standing in the same spot, noting whatever I could without measuring. The changes I caught were subtle — a new shoot, a shift in color, a slight encroachment on the neighboring space. The changes I missed were probably larger. Without instruments, without photographs, without the discipline of a scientist, I was a poor witness to growth. Most of us are.

Growth also hides in familiarity. The shrub belongs to the yard the way a word belongs to a sentence — present, functional, not requiring examination. We do not reread every word each time we encounter a paragraph. We do not remeasure every plant each time we cross the lawn. Efficiency demands summary. Growth demands comparison. The two impulses conflict, and summary usually wins.

What remains interesting to me is not the shrub's size but the gap between its growth and my awareness. That gap feels like a metaphor for other slow changes — in places, in relationships, in oneself — that proceed below the threshold of daily notice until something forces comparison. A photograph. A season. A return after absence.

The shrub continues to grow. I continue to walk past it. Occasionally I stop and look with the modest intention of seeing rather than confirming. The growth has not slowed. My perception has not caught up. I no longer expect it to. I find something honest in the lag — a reminder that living things revise themselves on schedules indifferent to our attention, and that noticing is always, in some measure, retrospective.

Autumn will strip the shrub bare again, and I will see its structure as if for the first time — the same illusion winter always offers. I know this cycle now. I still fall into it. Perhaps falling into it is part of the rhythm, the necessary forgetting that makes each spring's surprise possible.
