Also known as “yellow cups,” this plant is limited in its range to the
Mohave-Colorado Desert. Having smaller blossoms than the goldpoppy with
which it might be confused, this showy annual blooms March to May in dry
washes and on stony hills below 4,500 feet. The foot-high plants
sometimes form massed displays accented by splashes of bright red where
clumps of beavertail pricklypear mark small, rocky islands, or where
patches of ocotillos wave their scarlet-tipped wands in the spring
breeze.
