Reproduction
Research suggests that E. propullans rarely reproduces from seed on its own, but is highly dependent on vegetative reproduction, or limited cross pollination with Erythronium albidum, thus limiting population growth and spread of the species.
Erythronium propullans produces one stolon below the soil surface on the midway point of the stem on blooming plants; that stolon then produces a new bulb. On non-blooming plants, 1 to 3 stolons are produced directly from the bulbs, each ending in a new clone.

—Joanna Cole (20th century)
“The chief function of the city is to convert power into form, energy into culture, dead matter into the living symbols of art, biological reproduction into social creativity.”
—Lewis Mumford (1895–1990)
“It is so characteristic, that just when the mechanics of reproduction are so vastly improved, there are fewer and fewer people who know how the music should be played.”
