The long record
Each point is one year's peak of full bloom, placed on the date it fell. Higher on the page means earlier in the year. The tree does not read the calendar — but the calendar is starting to notice the tree.
The modern slice, as a calendar
Every year since 1990, one row. One square per day; the lit square is the day of full bloom. The dashed rule stands where the average bloom of 1900–1945 fell — April 14. Most of the petals no longer reach it.
* SQUARES ARE DAYS; DATES READ ON A COMMON 365-DAY CALENDAR. HOVER A YEAR TO DATE ITS BLOOM.
