More about this plant

Arctomecon humilis is an endangered flowering plant species in the family Papaveraceae. It is endemic to the Dixie Corridor in southwest Utah. A. humilis grows in a very harsh desert environment, requiring a specific soil type. The plant's common name is dwarf bear-poppy, which is indicative of the plant's jagged, three “clawed” leaves. The poppy is a perennial plant, meaning it blooms annually. The dwarf bear-poppy is protected under the Endangered Species Act as of 1979. The plant is threatened by urban development, off-road vehicle use, and mining. Although hard to estimate, its population has diminished significantly over the years. There are several plans to protect the poppy, including making the land it occurs on a protected area. Wikipedia →

Specialist native bees depend on it.

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