This adorable plant needs to keep its feet WET. Hence the common name of Marsh Marigold, heavy emphasis on the Marsh. This would work well in swales, alongside ponds, and low, wet areas in the landscape.
Vibrant green cupped leaves are punctuated with bright yellow buttercup flowers on elongated stems. The Marsh Marigold is a mounding plant that will spread to fill a space, use other water loving plants to help keep it in check.
Be careful not to confuse this native with an invasive look-a-like, Lesser celandine. Our native celandine (Caltha palustris) typically appears later than Lesser celandine (Ficaria verna) but their leaves and flowers look near identical. If you see the leaves and blossoms in March or Early April, you are looking at Lesser celandine and should get to pulling! Lesser celandine has yellow blossoms of 7-12 narrow petals while the native will begin blooming in Late April and will have rounder blossoms of 5-9 petals. Finally, if flowers are not present, look for bulblets forming at the stem nodes. If you see them, you have Lesser celandine, get pulling! This article from Lower Hudson PRISM contains excellent details regarding these two look-a-likes.
