Native Plants
Large white trillium is Ontario's provincial flower and a reliable signal of old-growth forest health — spotting it in Leeds and Grenville helps naturalists and restoration gardeners map where intact spring ephemeral communities still survive.
Someone found and photographed a large white trillium in Leeds and Grenville, Ontario, and the observation was verified as research-grade on iNaturalist. Large white trillium is a beloved spring wildflower that only grows in healthy, undisturbed forests — it takes years to establish and won't survive in degraded soil. Each confirmed sighting like this adds a real data point to the map of where these special woodland communities still exist.
