Similar species: Yellow floating heart, Yellow water-lily, White water-lily. Only forage with a confident ID. Never eat any wild plant, berry, nut or mushroom unless you are completely certain of the identification. Check every find against a reliable field guide, and when in doubt, don't.
Forage helps you discover and identify wild plants, but identification is never 100% certain. Many edible plants have toxic lookalikes. Never eat anything you find based only on what this app tells you. Always confirm with a field guide, an experienced forager or a local expert. The season score tells you where to look, too: it’s not a guarantee. Mind conservation law and property rights as well.
