Know before you buy
This plant is best suited for the margins of your pond. It thrives in moist, boggy soil or shallow water up to two inches deep, rather than being fully submerged.
The Caltha Polypetala is hardy in zones 4 through 7. It is a perennial that will go dormant in the winter and return with its signature yellow blooms each spring.
It prefers full sun to part shade. While it can handle some shade, providing at least a few hours of direct sunlight will encourage the most vibrant flower production.
Since this plant can reach up to two feet in height and spread, it is best to space them about 18 to 24 inches apart to allow for proper airflow and growth.
Unlike some other spring ephemerals that die back quickly, the Giant Marsh Marigold is known for holding its glossy, dark green foliage well into the summer months, keeping your pond edge looking lush.
