Rarity Notes
Globally secure (G5) and secure in both Ontario (S5) and Quebec (S5). Not listed under SARA or COSEWIC (S26). Despite provincial security, the species is considered Rare in the Ottawa-Hull region (S63) and has a restricted distribution in Ottawa with only 3 documented sites (S62), indicating local scarcity at the northern edge of its core range.

Ecological Context
Zizia aurea occupies moist meadows, fens, sedge meadows, and open floodplain forests across the Great Lakes-St. Lawrence lowlands. In Michigan it is common in swamps, low woodlands, and wet prairies (S7). Quebec herbarium specimens document it in sugar maple understory and along the St. Lawrence corridor (S54). Listed as Rare in the Ottawa-Hull flora (S63), with only 3 sites in Ottawa proper (S62), suggesting locally uncommon despite broad provincial security.

Permaculture & Companion Planting

Roles
Fortress/Barrier, Insectary Plant, Pollinator Attractor

S73/S29/S72 Evidence: Fortress/Barrier: S61 keyword match: thorns? (supporting signal only)] | Insectary Plant: S64 NPPBI 'beneficial insects' flag] | Pollinator Attractor: S73 [HIGH]: S64 Xerces listed (source-classified)]

Notes
PFAF recommends Zizia for woodland garden sunny edges and food forest plantings (S29). Its early bloom (Apr-Jun) fills a critical pollinator gap before most summer-flowering perennials, making it valuable paired with later-blooming prairie species. The flat-topped umbels support short-tongued bees, wasps, flies, and beetles (S61), serving as a biological control attractor.

S28 Meskwaki Drug=Analgesic+Febrifuge; S29 Febrifuge, Vulnerary, Hypnotic

Notes
The Meskwaki used a compound containing flower stalks as snuff for sick headache (analgesic) and the root for fevers (febrifuge) (S28). PFAF reports root tea as febrifuge, with the root also believed to be vulnerary and hypnotic (S29). Health Canada NHPID lists Zizia aurea as a homeopathic substance prepared from the root (S36).

❌ Not Edible   

Foraging Notes
PFAF rates edibility 2/5. Flowers with main stem removed can be added to tossed green salads or cooked like broccoli (S29). However, Moerman (S28) records no food use among Indigenous peoples, and OWSL (S3) flags the plant as toxic to mammals if ingested. Caution is warranted given the Apiaceae family includes deadly look-alikes.
