Naked Broomrape Orobanche uniflora

Naked Broomrape, in the family Orobanchaceae, is a small, hairy plant with one to three yellow to purple flowers and scalelike leaves.

Most broomrapes are plant parasites, and the completely parasitic species lack chlorophyll. Some species are serious crop parasites.

All of these specimens occurred at 5,000 - 6,000 feet elevation in the Hurricane Ridge area and on Blue Mountain, Olympic National Park, WA. Image 4 shows Orobanche growing along with Olympic Onion, Phlox and other plants.

Later in the summer, the flowers dry and seeds form. We found the flowers staying on the stalk, and needed to peel the flower off to see the seed.
