On our growing list Native Plants is Caltha palustris, Marsh Marigold. It’s a pretty buttercup flower on hollow stems and has glossy leaves that will reach 7″ by summer. This is a plant that is site specific, requiring wet feet so it’s great for bog gardens and the very edges of ponds. Grow in full sun to partial shade. The more sun the better the flowering, but appreciate shade from the hot summer sun. Native of northern North America, you can be assured it’s cold hardy since its growing range includes all of Canada!
