Lesser celandine is a low-growing perennial herb with shiny, somewhat lustrous dark green leaves that form a rosette. Leaves are kidney to heart shaped with smooth to coarse toothed edges. Each rosette forms a single bright yellow flower that is up to one inch wide. Seeds ripen early and the entire plant dies back by early summer, but not before it has developed numerous tubers in which it has stored energy for early growth the next year.
Lesser celandine is primarily a threat to native plants and native plant diversity in lowland woods and on flood plains. It outcompetes native plants through its extremely early seasonal growth and the development of a dense network of roots and tubers in the soil. Over time it forms extensive carpets in natural areas, crowding out native plants.
Photographed in my Pennsylvania (USA) garden where it runs over everything in sight.
