Beetleweed Galax urceolata
Beetleweed is a perennial shrub native to the lower 48 states.
More about this plant
Galax, the wandplant, wandflower, or beetleweed, is a genus in the flowering plant family Diapensiaceae, containing a single species, Galax urceolata. It is native to the southeastern United States from Massachusetts and New York south to northern Alabama, growing mainly in the Appalachian Mountains at altitudes of up to 1,500 m, where it grows in shaded places in forests. Galax urceolata can occur at multiple ploidy levels, an individual may be a diploid (2x), triploid (3x), or autotetraploid (4x) (autopolyploid). The cytotypes are neither morphologically nor geographically distinct, though there are slight climatic differences between the diploid and autotetraploid types. Outcrossing is likely to occur among cytotypes as well. Wikipedia →

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.
