Centromadia parryi subsp. parryi

Pappose tarplant, Pappose Tarplant

Family: Asteraceae · Type: perennial · Native

Conservation status: CNPS 1B.2

Pappose tarplant is a rare (CNPS 1B.2) California native perennial found in southern North Coast Ranges, southern North Coast Interior, southern Sacramento Valley, and northern Central Coast in grasslands, coastal salt marshes, and alkaline springs at elevations below 400 meters. Flowering from June to October, this plant produces yellow flowers with ray florets 3 to 5 millimeters long and distinctively coarse, glandular texture. Growing with erect stems up to 60 centimeters tall, it develops a robust and spreading habit characteristic of tarplants. Its leaves are notably hairy with yellow sessile or short-stalked glands, creating a textured and somewhat sticky appearance. The plant's yellow anthers and lack of purple lines on paleae further distinguish this distinctive tarplant in its native grassland habitats.
