A spring ephemeral, a perennial native to eastern North America. Cutleaf Toothwort (Cardamine concatenata).

The “toothwort” of its name is thanks to the appearance of its rhizome.

The Cutleaf Toothwort likes woods with mesic soils covered with lots of leaf litter. This certainly must be the description of the woods where I live. Many of these plants greet the spring each year up here, including a few spots where colonies have formed.

Buds protected by four pale green sepals open to reveal four barely pale pink petals. At the center of each flower is a style with a sphere topped stigma which are surrounded by stamens with green filaments of varying lengths topped by yellow anthers.

Many different pollinators visit these blooms. Fruit of the Toothwort is a slender pod about an inch long containing a single row of tiny seeds.

When the invasive, Garlic Mustard (Alliaria petiolata), starts growing in the area of a population of Cutleaf Toothwort its numbers soon decline. A good reason to fight those invasives.
