Flower: The stem tip puts out many flower buds. Each flower is on a stalk and has a cup of green sepals with pink tips. The flower stays in a tube to the top of the sepals then the four white to pink petals flare open. Five or six stamens surrounding a pistil stick out of the central tube.

Cut-Leaved Toothwort

toothwort plant

Toothwort is one of the earliest spring wildflowers to bloom. The plants form little green forests on the forest floor The green turns to pink as the flowers open.

At one time many of the plants didn’t make it to blooming as they became potherbs. The roots were used as a horseradish substitute and toothache remedy.

Although the leaves have teeth, the name toothwort did not refer to these teeth. There are tooth-like projections on the rhizomes and these gave the plant its common name.

In early spring places in the woods and ravines seem to be covered with toothwort. The sunny forest floor turns pink when the plants bloom. The trees leaf out as the plants are finishing making seeds. A short time later the plants have vanished even though summer has barely begun.

The plant has scattered seeds to start new plants and replaced the starch in its roots and rhizomes so it can bloom in the next spring. So the plant goes dormant avoiding heat and drought and being in deep shade under summer trees full of leaves.
