Rudbeckia occidentalis
Also called Western Cone Flower
Rudbeckia occidentalis, the western coneflower, is a tall native perennial of the daisy family from the northwestern United States, usually found in moist meadows. It grows best in moist, well-drained soil in sun or light shade, and its striking dark brown cone centre is its signature feature.
Rudbeckia occidentalis is a species of flowering plant in the family Asteraceae known by the common name western coneflower. It is native to the northwestern United States from Washington to northern California and east to Wyoming and Montana, where it grows in moist habitat types, such as meadows. It is an erect perennial herb growing from a thick rhizome, its mostly unbranched stem approaching two meters in maximum height. The large leaves are generally oval but pointed, and lightly to deeply toothed along the edges, growing to 30 centimeters long. The inflorescence is one or more flower heads with purplish bases up to 6 centimeters wide. There are no ray florets, just an array of reflexed phyllaries around the purple-brown center packed with disc florets. This center, containing the receptacles, lengthens to several centimeters in length as the fruits develop.
