I do not understand the data in this article.
Do all these trees bloom in unison? The scattered data seems to suggest there is variance between individual trees?
If there is variance, then how is decided what the start of spring is and at what point the tree as a collective species blooms?
- jfengel 6y agoThey all bloom within a few days to a week of each other. The variance is due to local conditions of sunlight, temperature, etc. The entire process is quite sharp: it goes from nothing to stunning blooms to empty in the space of a week or so. For normalization, they measure the "peak" bloom, the day with the most trees in blossom at once.
