Esteve’s Pincushion has pretty white flowers, mostly discoid. The plants bloom in early spring from February to May or June. Chaenactis stevioides Phyllaries on Esteve’s Pincushion are linear, narrowly tapered and hairy glandular, often cobwebby looking. Chaenactis stevioides Esteve’s Pincushion is an annual native forb or herb in the Sunflower Family. The florets are small but showy. Chaenactis stevioides Esteve’s Pincushion is found in the west central and southwestern United States and in Baja California and northern Sonora, Mexico. Chaenactis stevioides Esteve’s Pincushion has green or gray-green leaves, both basal and along stems. The leaves are alternate and concentrated on the lower stems. Note leaves are pinnatifid or even bi-pinnatifid. Chaenactis stevioides Esteve’s Pincushion grows up to a foot or more with 1 or multiple stems. Plants prefer elevations from100 to 6,500 feet and are found in lower and upper deserts, openings in chaparral, pinyon-juniper, mesas, plains, sandy or gravelly slopes and washes.

    Etymology:
    The genus Chaenactis is from the Greek words or root words "chaino" meaning "to gape" and also from "aktis" meaning "a ray"; thus the reference is to the enlarged outer corolla so common in the genus.

    The species epithet stevioides is named in honor of the Spanish humanist Pedro Jaime Esteve (1556) doctor and medical botanist.
