kolonnekruid

Kolonnekruid, scientifically known as Salsola kali, is an annual plant belonging to the Amaranthaceae family. It is native to Europe and Asia but has been introduced to many other parts of the world, where it can sometimes be considered an invasive species. The common name "kolonnekruid" refers to its upright, somewhat columnar growth habit.

The plant typically grows to a height of 30 to 120 centimeters. Its leaves are linear to needle-like, often sharp, and arranged spirally along the stems. During the summer months, small, inconspicuous flowers with greenish or reddish bracts appear. The fruit is a small, hard seed encased in a persistent calyx.

Kolonnekruid is well-adapted to dry, sandy, and disturbed soils, often found in coastal areas, roadsides, and waste ground. It is known for its drought tolerance. As the plant matures and dies, its brittle stems can break off at the base, and the wind can tumble the entire plant, acting as a tumbleweed. This dispersal mechanism is a characteristic feature of the species. In its native range, it plays a role in the ecosystem, but its introduction elsewhere can disrupt native plant communities and agricultural interests.
