Description
Berlandiera species are perennial herbaceous plants to subshrubs, which means sometimes woody at the base of the plant something. You can reach stature heights from 8 to 120 cm. They often form taproots. Green plant parts are usually hairy. The stems are erect to creeping and often branched. The change-constant leaves are petiolate or sessile. The leaf blades are depending on the type simple to pinnately lobed.
Individually or in branched inflorescences total basket- like inflorescences are formed. The flower heads have a diameter 12 to 30 mm. Most 14 to 22 bracts are in two to more than three rows. The inflorescence ground is cylindrical. There are chaff leaves present. Each flower head usually contains eight ( two to 13) tongue and 80 to more than 200 florets. The female and fertile florets ( = ray florets ) are yellow to orange - yellow; green on the bottom or red to chestnut -colored or with only nine to twelve nerves in these colors. The functionally male florets ( = disc florets ) are yellow or red to maroon color.
The black, hairy achenes possess only an annular Pappus he or missing entirely.
