An independent reference archive focused on native plant species and wildflower identification across Canadian provinces and territories.
Tansybrook is a reference archive based in Ottawa, Ontario. The site collects, organizes, and presents information on native wildflowers, indigenous flora conservation, invasive species identification, and native seed sourcing as they relate to Canadian growing conditions, ecozones, and provincial regulations.
The material here draws on published botanical field guides, provincial herbarium records, government species-at-risk assessments, and publicly available observation databases. Each article reflects current consensus from these sources at the time of the last revision date shown on the page.
The archive is limited to plants native to Canada or directly affecting Canadian native flora through invasion or displacement. It does not address ornamental horticulture beyond its intersection with native species conservation, nor does it cover food gardening, lawn care, or landscape design as standalone subjects.
Content is organized around three overlapping areas:
Tansybrook is operated by Tansybrook Media Inc., a federally incorporated company registered in Ontario (Ontario Business Registry #1009274631). The editorial work is produced in Ottawa.
Content is reviewed and updated on a rolling basis. Revision dates appear on each article page. If you identify a factual error or have supplementary information from a primary source, you can reach the editorial contact at info@tansybrook.org.
Nothing on this site constitutes professional botanical, ecological, or horticultural advice. Species identification from photographs and field descriptions carries inherent uncertainty. Do not rely on this archive alone when making decisions about plant removal, collection, restoration planting, or any activity with regulatory implications. Consult a qualified botanist or your provincial natural heritage authority for decisions requiring professional assessment.
