Reported in flower

Usually reported in flower mid-April to mid-May, middle week May 3–9.

From 284 records that show flowers. Not every photo of a plant in flower is marked as flowering, so this shows when people reported it in flower, not when it flowers.

Reported in fruit

Only 4 records here show fruit, too few to show a fruiting season. One needs at least 20 records from 5 different years.

What these results show

These results show when people recorded a species, not when or where it occurs. Missing weeks and low counts do not mean absence or scarcity, and counts are not abundance. Contributed records reflect where, when and what people chose to observe.
