I am looking for plants and/or seed of Erigenia bulbosa.

Blue Cohosh, Bunchberry, Eastern False Rue Anemone -- I think mine are above ground all summer. Trout lilies, Virginia Bluebells, Dodecatheon -- really seem ephemeral, though the shooting stars may linger through most of the year, with the candelabra of seed pods still there till next spring. Dicentra -- my Dicentra eximia is not ephemeral, but not sure about your species. Wild Leek -- leaves disappear, but round onion flower and seeds are there in the last summer-fall.

Harbinger-of-Spring or Erigenia bulbosa is a favorite of botanical field trips in late March or early April because it is the first such plant to bloom. I have never seen one more than 2" in height. You are describing a plant similar to Cardamine with one exception, Cardamine like all crucifers has only 4 petals. Sam
