The glacier lily (Erythronium grandiflorum) is one of the earliest wildflowers to bloom after snowmelt in the Rocky Mountains. Its ovaries and seeds are sensitive to late-season frosts. But because the species is a perennial, it can survive occasional years of reproductive failure by blooming the following year. By avoiding the cost of producing the relatively large fruit and seeds in one year, the plant may have better survivorship and be able to produce more flowers the next year.
