Körbchenblüte

Körbchenblüte is a German term that translates to "basket flower" and refers to a specific type of inflorescence, or flower cluster, found in certain plants. This arrangement is characterized by many small, sessile flowers that are tightly clustered together, often appearing as a single, large flower head. The individual flowers within the Körbchenblüte are typically inconspicuous on their own, but their collective arrangement creates a visually prominent structure.

This type of inflorescence is most famously seen in the family Asteraceae, which includes plants like daisies, sunflowers, and dandelions. In these plants, the Körbchenblüte is often referred to as a capitulum or head. The bracts, which are modified leaves, often surround the base of the cluster, forming an involucre that resembles a cup or basket, hence the name Körbchenblüte. This protective structure encloses and supports the developing flowers.

The function of the Körbchenblüte is to enhance pollination. The aggregated flowers present a larger, more attractive target for pollinators like insects. Different types of flowers can be present within the same Körbchenblüte; for example, in many Asteraceae, there are ray florets on the periphery, which are often brightly colored and petal-like, and disc florets in the center, which are typically smaller and tubular. This differentiation helps in attracting specific pollinators and facilitating pollen transfer. The term Körbchenblüte emphasizes the structural resemblance to a small basket, highlighting the way the individual florets are held together.
