tuber, specialized storage stem of certain seed plants. Tubers are usually short and thickened and typically grow below the soil. Largely composed of starch-storing parenchyma tissue, they constitute the resting stage of various plants and enable overwintering in many species.
What are examples of tubers?
Common examples edible of tubers include potatoes, jicama, sunchokes, and yams. Root tubers (like sweet potatoes or cassava) are often mistakenly classified within this category, but because they have swollen roots (rather than stems) they don't fit the technical bill for what a true tuber is.
What is a tuber and how does it grow?
Tuber. Tubers are formed from a stem or root. They store nutrients that allow the plant to grow the following season. Shoots grow upwards from many different places on the tuber. Examples of tubers are Dahlias, Begonias, Anemones and Potatoes.
What's the difference between a bulb and a tuber?
Bulbs generally have layers or scales of dormant leaves, like onions. Corms oftentimes have a rough, husk-like layer of protection around them, such as crocus. Tubers, on the other hand, may have a thin skin protecting them, as potatoes do, but they will also be covered with nodes, buds or “eyes.”
What is a tuber flower?
Tubers are also underground stems. They differ from corms in that they are not the base of the stem. Common flowering tubers include anemones, begonia and cyclamen. Tubers have nodes (on potatoes, we call them eyes) that can appear anywhere on the tuber and sprout both new shoots and new roots.
