Naked broomrape is an attractive perennial wildflower with single,erect floral pedicels from 5-15 cm high. The main stem is 0.5-2 cm long and is typically buried under the soil. The herbage is typically finely glandular-hairy.
The inflorescence consists of 1-3 flowers on long pedicels. The calyx is 6-12 mm long with the calyx tube from 2-4 mm long and the subequal lobes from 4-9 mm long. The corolla is 15-25 mm long and yellowish to purplish in color. The tube is curved with the lobes measuring 2-7 mm long with rounded, finely fringed tips. The anthers are 0.9-12 mm long, ranging from glabrous to woolly-pubescent.
Naked broomrape is parasitic on many saxifrages, sedums and members of the Asteraceae.

variety purpurea: Flowers purplish with the throat fairly expanded and spreading. The limb is large and expands widely. The corolla measures 2-3.5 cm long. The anthers are woolly.
Naked broomrape may be found in open, moist grasslands or occasionally in moist woodlands from the lowlands to moderate elevations in the mountains.
Naked broomrape may be found from the Yukon south to southern California and east to Newfoundland and hence south to Florida.
In the Columbia River Gorge it may be found between the elevations of 100'-3000' between Stevenson, WA and Biggs, OR.
