Folded Calicoflower Downingia ornatissima
Folded Calicoflower is an annual wildflower native to the lower 48 states. It blooms Apr – May.
More about this plant
Downingia ornatissima is a species of flowering plant in the bellflower family known by the common name folded calicoflower. This showy wildflower is endemic to California, where it is a resident of vernal pools and other wet places in the Central Valley. This annual grows an erect, branching stem with usually one tubular flower at the top of each branch. The flower has an upper lip made up of two narrow, pointed lobes in shades of light purple, and a lower lip made up of three lobes fused into one surface, which is the same color as the upper lip and has a central field of white with two prominent yellow projections. The flower is similar to those of other downingias, except it is lightly crinkled, with the upper lobes often curled back and the edges of the lower lobes uneven. The dark blue anther just emerges from where it is tucked between the upper lobes. Wikipedia →

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.
