Reported in flower
Usually reported in flower early April to late April, middle week Apr 12–18.
From 791 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-April to early May, middle week Apr 26 – May 2.
From 22 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.
Identification

Telling it apart

From 1,660 records placed within 100 m, beside all Ohio records placed the same way. People record where they go, so this shows where records come from, not where the species lives. Land cover: USGS Annual NLCD, 2025 (opens in a new tab)
Finer identifications
Some Ohio records of this species were identified to a subspecies:
Every one of these records counts toward yellow trout lily'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.
Names: Catalogue of Life.
Sources
Where these results come from
Records from iNaturalist research-grade observations and expert-identified GBIF datasets, CC0, CC BY and CC BY-NC. Sources
Seasons use the published method and its evidence thresholds. Methods
A spreadsheet (CSV) with a link to each record, on iNaturalist or GBIF. Records whose location was hidden by the observer or the source are counted but not linked.
