Life histories of the perennial geophyte Erythronium grandiflorum (Liliaceae) in Colorado subalpine transplant garden from annual measurements, 1991 onward
In an outdoor garden at Irwin, Colorado, we established glacier lily plants in open-bottomed PVC pots that protected them from gopher attack. The initial cohorts were excavated from field sites as mature corms of unknown age. Later cohorts were grown from seed, so their ages are known. Each spring since 1991, we have noted fruit and flower production. In August, after the aboveground parts have died back, we exhume the plants, wash off the soil, weigh the corms, characterize their morphology, photograph them, and replant them. If a corm splits, we replant the pieces in separate pots. The study is ongoing, with 264 plants in 2019. Main findings through 2020: plants produce 0-4 flowers per year, depending on size; most plants flower each year; death is rare, with many plants having survived the entire study; setting a fruit reduces corm substantially (cost of reproduction); plants appear to regulate weight by adjusting flower production, and by splitting; genotypes vary in splitting propensity. Oddly, mortality is higher in very large corms than in mid-sized ones. Evidence for senescence is scant.

Data from: Early spring warming may hasten leaf emergence in Erythronium americanum
Premise of the study: Climate change is making spring arrive earlier than in the past, causing some species to alter the timing of their spring activities. This study addressed whether Erythronium americanum Ker Gawl. (trout lily), a common spring ephemeral, can hasten its spring emergence if exposed to early spring warming. Methods: I collected corms of E. americanum in the fall, overwintered them in soil, and exposed them to warming in either mid (early treatment) or late (late treatment) February. The timing of leaf emergence was monitored and compared between treatments. Key results: Leaves exposed to early warming emerged earlier than those in the late treatment. Bud break happened closer to date of exposure to warming in the late treatment than in the early treatment. Conclusions: Spring ephemerals may be able to produce leaves early in response to early spring warming induced by climate change. Risk of late frost and eventual shading by the canopy may limit the duration of a potentially extended growing season.
