Records per week from 614 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 407 dates. Latest record: November 2025.

Reported in flower

No flowering season shown here. The weeks are still too uncertain to show a season.

Reported in fruit

Usually reported in fruit early August to early November, middle week Sep 13–19.

From 165 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.

Finer identifications

Some Ohio records of this species were identified to a variety:

Ampelopsis glandulosa var. brevipedunculataporcelain-berryvariety

Every one of these records counts toward Porcelain Berry's season above.

Why some records go further than species

Many plants vary from place to place. Botanists name these groups at three levels below species: subspecies, variety and form, from the broadest difference to the smallest. Observers and experts only identify a record that far when it shows enough detail to tell them apart. Records without that detail count at the species level.
