Cardamine flexuosa aka Greater Bittercress

Cardamine flexuosa, commonly known as wavy bittercress or wood bitter-cress, is an herbaceous annual, biennial, or short-lived perennial plant in the cabbage family (Brassicaceae). It is a hardy plant that prefers moist or wet soil and can grow in semi-shade or no shade. The plant is self-fertile and is in flower from April to September, with seeds ripening from May to September. Wavy Bittercress is an incredibly rare houseplant that thrives with regular watering and long-lasting, direct light. The soil should be good at retaining moisture, and it should be less than 1 foot from a window. No additional fertilizers should be necessary for proper growth, just be sure to repot it each time it doubles in size.
