March 28, 2024April 9, 2024 Agric4Profits

Alfalfa inflorescence, known scientifically as Medicago sativa, features a unique inflorescence, or flowering structure, characterized by clusters of small, purple to blue flowers. These flowers are arranged in a spiral-shaped configuration along a central stem called a raceme.

Each flower consists of five petals and forms a pea-like shape. The inflorescence of alfalfa typically emerges from the upper portion of the plant, creating a visually striking display.

This flowering pattern not only adds aesthetic appeal but also serves as a crucial stage in the plant’s reproductive cycle, attracting pollinators such as bees and other insects.
