In Ohio
Late June to mid-September, middle week Aug 2–8
Records per week from 1,312 records in 10 of the 10 years from 2016 to 2025. Shows when people recorded it, not how common it is. The grey bars show how many records of all species were made here each week, so you can see when recording itself was high or low; the season is not adjusted by them.
Recorded on 593 dates. Latest record: November 2025.

Reported in flower
Usually reported in flower early July to mid-September, middle week Aug 2–8.
From 187 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
No fruiting season shown here. Most records come from a single year, so a season is not shown yet.
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.
