If you have planted daffodils or crocuses, then you have grown ephemerals. Bulbs and corms produce a succession of colorful blooms from January to May. Once they complete their display, they retreat and rest underground until the next spring. . . . In the United States, though, the term “spring ephemerals” usually refers to native North American wildflowers whose natural habitat is a deciduous forest.
It's the time of year when Gardeners talk enthusiastically about “Spring Ephemerals,” using this term to describe native wildflowers, such as Virginia Bluebells, Trout Lily, Toothwort, Spring Beauty, Bloodroot, Trillium and Woodland Phlox. The word 'ephemeral' often means short-lived, but in the case of native plants, transitory is more accurate.
