Aegopodium podagraria L.
Ground elder, herb gerard, bishop’s weed, goutweed, gout wort, snow-in-the-mountain, English masterwort, wild masterwort, bishop’s goutweed
Native to Europe and Asia, ground elder is naturalized or even invasive in parts of North America. They are planted in gardens, but they spread aggressively and are difficult to control.
Plants: Up to 4–39″ (10–100 cm), with erect, hollow, grooved stems.
Leaves: Ground elder leaves somewhat resemble those of elderberries, hence the name. Upper leaves occur in triples (“ternate”), each leaf 1–3″ (2.5–7.6 cm) long, and toothed. Garden variants are often variegated, but wild leaves are all green.
Flowers: Large umbrella-shaped umbels of flowers are in turn split into secondary umbels called umbellets. Each umbel is 2–4½″ (6–12 cm) around. Each umbellet has 15 to 20 stems (“pedicels”), each topped with a tiny white flower with five petals.
Fruits: 1/16–⅛″ (3–4 mm) long.
Habitats: Disturbed habitats, floodplains, forests, meadows, and fields.
Edibility: Leaves are edible raw or cooked, with a flavor likened to celery or lemon and parsley. Like spinach, they cook down a lot, but they can be used in soups, stews, or salads.
