In the Scifres-Maier Woods in Celery Bog Park, a toothwort (Cardamine concatenata) and a Spring Beauty (Claytonia virginica) are just about ready to flower. These are two of our commonest spring wildflowers. Rust fungus is growing on the Spring Beauty, adding some color to the natural world close to the ground. The rust that lives on Spring Beauty is called Puccinia mariae-wilsoniae. Picture taken April 5, 2011.
