Bushy Bird's Beak Cordylanthus ramosus
Bushy Bird's Beak is an annual wildflower native to the lower 48 states. It grows to 1 ft and blooms Jul in full sun – part shade, with brown fruit. A host for pollen-specialist native bees.
More about this plant
Cordylanthus ramosus is a species of flowering plant in the family Orobanchaceae known by the common name bushy bird's beak. It is native to the western United States where it grows in mountains and plateau, including the sagebrush of the Great Basin. It is an annual herb producing an erect, branching gray-green form, often tinted with red, becoming bushy at its most robust and appearing not unlike a sagebrush. The small leaves are narrow and linear or divided into several narrow, thready lobes. The inflorescence is a small spike of a few flowers surrounded by bracts which are linear or divided into narrow, thready lobes like the leaves. The bracts are faintly woolly and occasionally bristly in texture. The flower is one to two centimeters long with a hairy yellow pouch enclosed in darker, tougher reddish sepals. This plant had a number of historical medicinal uses for the Navajo people, who used it as an emetic. Wikipedia →

✦ Bees specialist-bee host · 2 bee visitors
Specialist native bees depend on it.
Some native bees are pollen specialists (oligolectic) — they raise young only on pollen from particular plant genera. Cordylanthus is a recorded specialist-bee host, so losing it can mean losing the bee that relies on it.

How we know this (1) 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.
