Yellow Marshcress is native to parts of Africa, and much of Asia, Europe and Eurasia, North America and the Caribbean. Yellow Marshcress is also known as Marsh Yellowcress, Bog Yellowcress, Watercress.

Yellow Marshcress displays an upright, spreading perennial growth habit, reaching up to 1.5 ft tall with a spread of approximately 1 ft. Yellow Marshcress produces small clusters of white or yellow flowers.

Leaf size: approximately 3 inches.

Rorippa palustris requires watering every 2–3 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Yellow Marshcress thrives in full sun to part shade.

Rorippa palustris grows best at temperatures of 50–75°F. Yellow Marshcress prefers humidity levels of 40–70%.

Moist, fertile soil with good drainage. Good drainage is essential for Yellow Marshcress to prevent waterlogging, which leads to root rot and fungal issues.

Feed Yellow Marshcress every 6 months during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.

Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.
