Fryingpans Eschscholzia lobbii
Fryingpans is an annual wildflower native to the lower 48 states. It blooms Mar – May. A host for pollen-specialist native bees.
More about this plant
Eschscholzia lobbii is a species of poppy known by the common name frying pans. It is endemic to California, where it grows in the Central Valley and adjacent Sierra Nevada foothills. The frying pans is a small annual herb growing from a patch of segmented leaves with pointed leaflets. It produces erect stalks up to 15 centimeters in height each bearing a single poppy flower. The petals are about a centimeter long and bright yellow to somewhat orange. The fruit is a capsule 3 to 7 centimeters long containing tiny brown seeds. Wikipedia →

How pollinator value is scored →❧ Caterpillar hosts ~2 caterpillar species
Eschscholzia supports ~2 caterpillar species.
Native butterfly & moth caterpillars are the base of the terrestrial food web — most songbirds rear their young almost entirely on them. As a host for native Lepidoptera this is a modest genus.

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

How we know this (3) Methods & honest limits
A recorded categorical fact: each species is tagged C3 (standard), C4 (heat/water-efficient) or CAM (succulent, night-time CO₂ uptake) — or a facultative combination. We only show a trait card for the noteworthy C4/CAM cases; C3 is the unremarkable majority, kept in the data but not surfaced as a card.
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.
