Wildflowers & Herbaceous Plants of Schuylkill County

746 documented taxa of the herbaceous flowering plants — wildflowers and forbs recorded in Schuylkill County, Pennsylvania — by iNaturalist research-grade, herbarium / USDA specimen records as of 2026-06-18 — with detailed accounts of the most notable, signature, and introduced species.

How this list is sourced. County presence is anchored to records filtered to Schuylkill County — iNaturalist research-grade observations (place 1470), with herbarium-voucher and USDA PLANTS records shown as a separate, specimen-documented tier. Observation counts are an effort-biased signal of recording activity as of 2026-06-18, not a census. Biology and identification draw on state and museum authorities; per-species links go to Wikipedia for cross-reference only.

Conservation ranks here are relayed from NatureServe / iNaturalist and are not definitive Pennsylvania ranks — confirm against the Pennsylvania Natural Heritage Program (PNHP) before relying on them.

Detailed accounts

38 of the 746 documented taxa are profiled in detail below — the most-recorded, signature, introduced, and notable species. The complete checklist follows.
