Caltha palustris is a little-known native bog plant known as marsh marigold. A denizen of regions with minimal summer heat (Maine west into the Dakotas, and south down the spine of the Appalachian mountains), marsh marigold grows where you would expect to find a marsh. This ranunculus relative is topped with bright yellow flowers starting in April (NC). Caltha palustris can reach 18" tall x 18" wide, with the round, textured green leaves held at the end of hollow stems. If you're ever lost in a swamp, marsh marigolds can be cooked, but don't eat 'em raw. Marsh marigold can spread to make a large patch, but sadly, much of what is sold as caltha palustris is actually it's evil cousin, the highly invasive Ranunculus ficaria, so be very wary.
