A word about the bloom time chart:

This is a multi-year chart that compares bloom times since 2005; it is ongoing.
The chart uses the standard Arboretum Locations keyed to the Map on this web site.
In the future, I hope to link the chart to annual weather reports so that one can see
the effect, if any, of spring onset times and temperatures.

I update the chart from field work once a week during the season and will post these
updates on this web site as time allows.

Early Spring 2020 data limited due to COVID-19 campus restrictions.
