Recording in Ohio · records of all species each week, 1,691,199 in all

Records per week from 4,905 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 1,350 dates. Latest record: December 2025.

Reported in flower

Usually reported in flower late June to mid-October, middle week Aug 2–8.

From 101 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

Usually reported in fruit mid-July to late October, middle week Sep 6–12.

From 428 records that show fruit. Not every photo of a plant in fruit is marked as fruiting, so this shows when people reported it in fruit, not when it fruits.

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.
