Summary

Cardamine amara, commonly known as Large Bitter-Cress, is a perennial evergreen herb native to a variety of habitats in Eurasia, including damp woodlands, stream banks, and moist meadows. This species reaches up to 70 cm (28 in) tall with upright, mostly unbranched stems. The leaves are pinnate with three to 13 leaflets, and the plant produces showy clusters of white flowers, occasionally tinged with pink or purple, each petal measuring 8–14 mm (0.3–0.6 in) long. Flowering occurs from late spring to early summer.

Large Bitter-Cress is valued for its early spring blooms and its ability to thrive in moist, shady garden spots. It is often used in naturalistic plantings, around ponds, and in woodland gardens. It prefers consistently moist soil with medium drainage and can tolerate full sun to part shade conditions. While it is not a common culinary herb, it is edible and has a peppery flavor similar to watercress. Gardeners should be aware that it can self-seed prolifically under ideal conditions, potentially becoming weedy.CC BY-SA 4.0
