Every plant flowers for a stretch of days, and that stretch is its window. A window is not a switch. The first flowers open thinly, the plant builds to its fullest in the middle, and the last flowers fade over the final days. The days at either end count for much less than the days in the middle.

The useful way to read a window is against the year's nectar, not on its own. Phacelia out for six weeks in May sits under a flow that is already rising; the same six weeks in August sits over almost nothing. The plant is the same and its worth to the hive is not.

In this game every planting is drawn as a bar over the curve of your year's nectar, rising and fading at each end.
