Trillium grandiflorum in the foreground and the smaller Thalictrum thalictroides in the background are both spring ephemerals of North American deciduous forests. An ephemeral plant is a plant with a very short life cycle or very short period of active growth, often one that grows only during brief periods when conditions are favorable.
Plants whose life cycle is significantly less than the time of a growing season are deemed ephemeral. [37] Winter annuals, Epilobium and Senecio vulgaris are examples of ephemeral plants. [37] [38] The conditions for ephemeral plants are markedly present in deserts. [38] Animals can be ephemeral, with brine shrimp and the mayfly being examples.

All parts of the plant are poisonous when consumed by humans and other mammals, [10] because it contains cardiac glycosides similar to those present in Adonis vernalis. [ citation needed ] Glycosides of this type stimulate the heart when administered in small doses, but in very large doses may cause serious, often irreparable heart damage.

Growing to 25 cm (10 in), it is a spring ephemeral, with foliage that appears in spring and dies down to its tuberous rootstock in summer. It is cultivated for its deeply ...
Corydalis cava is a species of flowering plant in the family Papaveraceae, native to moist, shady, woodland habitats throughout most of mainland Europe, although commonest in central and southeast Europe. Its range extends from Spain in the west to Ukraine, Belarus and the Caucasus in the east and as far north as Sweden.
The plant develops very early in the spring and flowers mid-spring. In early summer, each fertilized flower produces four seeds within wrinkled nuts. The plant then goes dormant till the next spring. [3] The flowers attract long-tongued bees, such as bumblebees, butterflies, moths, skippers, hummingbird moths, flower flies, bee flies, and ...
