Red tubes, commonly referred to as Redstem Filaree or Erodium cicutarium, are a type of flowering plant that belongs to the Geraniaceae family. Native to Europe, Western Asia, and North Africa, this plant has become naturalized in many parts of the world, including North America.

The maturation of red tubes is a complex process that involves multiple stages of growth and development. Understanding these stages and the factors that influence them can help gardeners, farmers, and researchers optimize the cultivation and management of this plant species.

Red tubes are annual or biennial plants that grow up to 30-60 cm (12-24 inches) in height. They have slender stems with small, delicate leaves that are typically divided into narrow segments. The plant produces small, pink or red flowers that are arranged in clusters, which eventually develop into long, tube-shaped seed pods.
