Season

When it is recorded

In Ohio

Early February to early May, middle week Mar 8–14

Show over the bars
Recording in Ohio · records of all species each week, 1,691,199 in all

Records per week from 550 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 278 dates. Latest record: May 2025.

Reported in flower

Usually reported in flower early February to late March, middle week Mar 1–7.

From 49 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

Only 9 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.

Identification

How to identify it

Telling it apart

From what Ohio’s records show. Only what the records support is shown.

Often confused with

  • yellow woodland anemone Anemone ranunculoides75 identifications worldwide named one where the other was meant
  • lesser celandine Ficaria verna68 identifications worldwide named one where the other was meant
  • marsh marigold Caltha palustris15 identifications worldwide named one where the other was meant
  • basswood Tilia americana13 identifications worldwide named one where the other was meant

From iNaturalist’s similar-species counts, refreshed monthly: confusions in Ohio first, then worldwide. Only species with an Ohio result are listed.
