Redstem Springbeauty Claytonia rubra
Redstem Springbeauty is an annual wildflower native to Canada and the lower 48 states. It blooms Mar – Jul. A host for pollen-specialist native bees.
More about this plant
Claytonia rubra is a species of wildflower in the springbeauty family known by the common names redstem springbeauty and red miner's lettuce. It is native to western North America from southwestern Canada to the United States of America extending from The Black Hills and western slopes of the Rocky Mountains to the Cascade and Coast Range, Ochoco and Wallowa Mountains south to the Warner Mountains, Yolla Bolly Mountains, and Sierra Nevada and Transverse Ranges [Mt. Pinos and Mt. San Gorgonio], where it is found in coniferous forests and shrublands. Wikipedia →

Specialist native bees depend on it.
Some native bees are pollen specialists (oligolectic) — they raise young only on pollen from particular plant genera. Claytonia is a recorded specialist-bee host, so losing it can mean losing the bee that relies on it.

How we know this (2) Methods & honest limits
We take the plant’s U.S. county range and look up each county’s long-term climate, then summarise: native rainfall = the median annual rainfall across its counties; heat tolerance = the warm end (90th percentile) of average temperature across its range (mirroring how our cold-hardiness floor uses an extreme). Counties + medians blunt the roadside/observer bias that makes point-level climate unreliable. Needs at least five placeable counties.
Honest limits: A realized, sampling-biased niche (where it has been recorded, not its physiological optimum), and county climate is coarse — large Western counties span deserts and mountains. Derived guide, never a measured fact.
McKenzie et al. assigned each species a flower colour with a GPT-4V vision model over iNaturalist photos. We use the confident tier plus a separately-labelled lower-confidence top-up (mostly inconspicuous green/brown flowers), and render it as a small tint — never as an asserted fact, and kept out of the written synopsis.
Honest limits: AI image inference (~87% expert agreement on the confident tier); a decorative, confidence-tiered indicator, not a measured trait.
