Prostrate lupine – a tiny beauty: Friday Flowers

We stopped at the Kiger Gorge overlook on Steens Mountain in August and saw tiny flowers at our feet. These are prostrate lupines, Lupinus lepidus var. lobbii. I put my hand in the picture just to give you an idea of the scale.

This native plant grows in alpine habitats. The tiny blue or purple flowers measure 1/3 inch across. The plant grows to a height of 4-6 inches. Another common name for this low profile plant is “dwarf lupine.” Lupines have distinctive leaves that are almost star-like in form. The seedpods are often covered with soft “hair.”

Prostrate lupine blooms in June, July, and August. The plants I saw in late August were growing at 9,000 feet in elevation. Everything blooms later there.

This lupine ranges north to the Cascade and Olympic mountains in Washington State, south to northern California and east to western Idaho and Nevada. Prostrate lupines grow on talus slopes and in rocky pumice soils at high elevations.

Prostrate lupine is a perennial that grows in areas with heavy snowfall in the winter and short dry summers. Like other lupines, its flowers attract pollinators.
