About this week's featured blooms

  1. Cutleaf toothwort (Cardamine concatenataWith delicate, dangly white flowers, this widespread wildflower has toothlike projections on its fleshy roots. It is sometimes called pepperroot for its spicy-flavored rhizomes.
  2. Autumn flame red maple (Acer rubrum ‘Autumn Flame’Red maple is one of the earliest trees to flower in spring. The flowers give the tree’s branches an overall red cast. The tree blooms before its leaves unfold because it depends on wind to waft pollen from male to female flowers and fertilize them. Leaves would get in the way.
  3. Mayapple (Podophyllum peltatumThe umbrellalike leaves of mayapple are a familiar sight in spring from Maine to Texas, growing in large colonies that spread by underground stems from a single plant. A white flower, borne beneath the leaves, develops into a green fruit.
  4. Bear oak (Quercus ilicifoliaMale flowers, which will develop into dangling catkins, emerge on twigs of bear oak, a shrubby plant native to the eastern United States. Oaks, like many trees, are wind-pollinated, with male and female flowers on the same plant.
  5. Virginia bluebells (Mertensia virginicaThis wildflower creates a blue carpet in May in parts of the East Woods. Native across the eastern United States, this flower  was dubbed “bluebell” by early colonists because it reminded them of the English bluebell (Hyacinthoides non-scripta), an unrelated plant that has blue flowers and grows in British woodlands in spring.
