Reported in flower
Usually reported in flower early May to late May, middle week May 17–23.
From 62 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 early August to mid-October, middle week early September. An earlier season is not shown: most records are from one year.
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:
Every one of these records counts toward Solomon's plume'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.
