Native

Pinyon Gilia is an annual wildflower native to the lower 48 states. It blooms Jun.

More about this plant

Aliciella subacaulis is a species of flowering plant in the phlox family known by the common name pinyon gilia. It is native to the western United States from California to Wyoming, where it grows in several types of habitat, such as sagebrush and desert woodlands. This herb produces a glandular stem up to about 30 centimeters tall, surrounded at the base by an erect cluster of lobed leaves each up to 7 centimeters long. There are also smaller, unlobed leaves along the stem. The inflorescence is a loose cluster of purple-washed white flowers with yellow-spotted throats. Wikipedia →

How we know this (1) Methods & honest limits
Climate niche (heat tolerance & native rainfall) Derived

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.

Realized-niche / climate-envelope approach (Pearson & Dawson 2003; Soberón 2007). Climate: NOAA NCEI nClimDiv county normals (1991–2020).
Derived values are computed from open data by a published method — labelled, cited, and never shown as a direct observation. Full methodology →
