California Coneflower, with the botanical name
Rudbeckia californica
, is a deciduous perennial species in the Sunflower or Aster Family (Asteraceae). It is a large showy flowering plant, that grows in seeps, meadows and wetlands, at elevations of 400-7,800 feet, in Red Fir Forest and Mountain Meadow habitats from the central Sierra Nevada and in the Klamath Mountains into into southwestern Oregon
The Klamath Coneflower, a former variety of this species named
Rudbeckia californica
var. intermedia and endemic to northwestern California in the Klamath Mountains, has been reclassified as the species
Rudbeckia klamathensis
.
California Coneflower grows from a thick rhizome, reaching 3 to 6 feet (1-2 m) tall. It has large leaves that can be up to 1 foot (30 cm) long, and are lance-shaped to oval, smooth-edged or lobed. Most of these large leaves are basal, with a few alternately arranged along the bloom stems.
The yellow flower has an inflorescence that is a usually solitary sunflower-like flower head with a base up to 2.5 inches (6 cm) wide lined with several ray florets, each of which are 0.75 to 2.5 inches (2-6 cm) long. The yellow ray florets extend outwards and then become reflexed, pointing back down along the stem. It blooms in July and August. The disc florets filling the button-shaped to conical to cylindrical center of the head are greenish yellow. The fruits are achenes tipped with a pappus of scales.
California Coneflower prefers partially shaded, cool, and seasonally to always moist garden conditions.
