Spring ephemerals come in a stunning variety of shapes and colors. They begin the season with the early-season cutleaf toothwort, Cardamine concatenata , notable for its spray of small white flowers, and its finely cut foliage with toothlike projections on its leaves. Mayapples, Podophyllum peltatum , also bear white flowers, large nodding blooms carried under their umbrella-shaped leaves. These earliest bloomers are followed by Virginia bluebells, Mertensia virginica ,a big-leafed beauty with pink buds that open into baby blue, bell-shaped flowers.
