Reported in flower
Usually reported in flower mid-June to mid-August, middle week late July, and again late August to mid-September, middle week mid-September.
Reported in fruit
Only 2 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.

Finer identifications
Some Ohio records of this species were identified to a subspecies:
- Convolvulus sepium subsp. sepiumsubspecies
A few other records were identified to other subspecies.
Every one of these records counts toward Convolvulus sepium'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.
