Phenology: Flowering spring–summer (May–Jul).
Habitat: Roadsides, fields, sagebrush scrub, and open pine or aspen forests in valleys and foothills
Elevation: 1200-2400 m
Calif., Idaho, Mont., Oreg., Utah, native to Eurasia.
I have not seen specimens from Washington and Wyoming; Adonis aestivalis is documented from Idaho immediately across the border from those states.
Except for details of the achenes and the subtle differences in orientation of sepals and petals, Adonis aestivalis is much like A. annua. Adonis aestivalis has been divided into three variable subspecies, although only two [Adonis aestivalis subsp. aestivalis and subsp. parviflora (de Candolle) N. Busch] seem to be well delimited morphologically and geographically in Eurasia (C. C. Heyn and B. Pazy 1989). North American material is not readily assigned to either subspecies.
Petal color has been variously reported; in the flora only orange with a dark basal blotch is confirmed.
