Fruit Features

The fruit of velvet centaurea is characterized by its cylindrical achenes, which are a type of dry, single-seeded fruit that does not open at maturity. These achenes facilitate efficient distribution as they are small, typically measuring just a few millimeters in length. The surface of the achenes may vary in texture but often appears somewhat roughened, aiding in dispersal by clinging to animal fur or feathers. The color can range from a muted brown to a more greyish hue, blending well with the surrounding soil. The shape and texture of these fruits are key traits which help to differentiate velvet centaurea from other species and are crucial for its successful propagation.
