Chaenactis stevioides, Esteve’s Pincushion

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 from 100 to 6,500 feet (30 – 1,800) and are found in lower and upper deserts, openings in chaparral, pinyon-juniper, mesas, plains, sandy or gravelly slopes and washes.

Importance to Wildlife, Birds and Livestock

Special Value to Native Bees, Butterflies and Insects
Insects may feed from the florets.

The genus Chaenactis is derived from the Greek word chaino "to gape" and aktis "a ray"; the references because several species the ray florets are enlarged to a wide-open "gaping ray like mouth". The genus Chaenactis was published in 1836 by Augustin Pyramus de Candolle.

The species epithet stevioides is named in honor of the Spanish botanist, physician and humanist Pedro Jaime Esteve (1,500-1,556).
