Illustrated Flora of Prince Edward Island
The Flora of Prince Edward Island project (2017-2022) was initiated by the Atlantic Canada Conservation Data Centre in partnership with the PEI Museum and Heritage Foundation and Nature PEI. This work expands upon Erskine (1960), Catling et al. (1985), and Day & Catling (1991). It includes dozens of new species records, modern taxonomy, and refined understanding of conservation statuses. The project features fully-illustrated online keys to all the vascular plants of Prince Edward Island.
The illustrated key below is designed to make identification accessible by providing visual examples of the characters in each couplet. Begin the key by clicking on the picture that most resembles the plant you are trying to identify. Shortcuts to families and technical text-only keys are available by clicking the 'Family Keys' and "Technical Key" links at the bottom of this page. A periodically updated checklist of PEI flora can be found here.
