knollenpflanzen

Knollenpflanzen are plants that store nutrients in underground swollen stems or roots, known as tubers. These tubers serve as a food reserve for the plant, allowing it to survive unfavorable conditions such as drought or cold and to produce new shoots when conditions improve. Common examples include potatoes, yams, and dahlias.

The formation of tubers is a form of vegetative reproduction, enabling the plant to propagate itself without relying on seeds. When a tuber is planted or falls to the ground, it can sprout and grow into a new, independent plant. This method of reproduction is often more reliable and faster than seed propagation for certain species.

Many knollenpflanzen are important food crops for humans and animals worldwide. Potatoes, for instance, are a staple food in many cultures, providing carbohydrates, vitamins, and minerals. Sweet potatoes and yams are also significant food sources, particularly in tropical and subtropical regions. Ornamental plants like dahlias are cultivated for their visually appealing flowers, with their tubers also serving as a means of propagation for gardeners. The diversity of knollenpflanzen is vast, encompassing a wide range of species with varying adaptations and uses.
