Phenology observation

Flowers
LATE MIDDLE EARLY FIRST BUD BURST NONE
Late Flowering
Most flowers have wilted or fallen off (over 95%) or most pollen has fallen.
Notes
We had a hard frost on the evening and night of April 17. Most of the flowers on this shrub had already started to wilt, but there were some that hadn't. Now they are all brown, wilting, or frost-bit but still white (only a few in this category).
