Tubers help plants perennate (survive winter or dry months), provide energy and nutrients, and are a means of asexual reproduction. [1] Stem tubers manifest as thickened rhizomes (underground stems) or stolons (horizontal connections between organisms); examples include the potato and yam.

Tuber is a genus in the fungal family Tuberaceae, with estimated molecular dating to the end of the Jurassic period (156 Mya). [2] It includes several species of truffles that are highly valued as delicacies.
A geophyte (earth+plant) is a plant with an underground storage organ including true bulbs, corms, tubers, tuberous roots, enlarged hypocotyls, and rhizomes. Most plants with underground stems are geophytes but not all plants that are geophytes have underground stems. Geophytes are often physiologically active even when they lack leaves.
The plants often grow together in crowded colonies and spread by runners at or just under the soil surface. In late summer the plants produce tubers that are twice as long as wide, [9] each typically measuring 0.5 to 5 cm (1 ⁄ 4 to 2 in) in diameter. [8] The plant produces rosettes of leaves and an inflorescence on a long rigid scape.
Dioscorea alata – also called ube (/ ˈ uː b ɛ,-b eɪ /), ubi, purple yam, or greater yam, among many other names – is a species of yam (a tuber).The tubers are usually a vivid violet-purple to bright lavender in color (hence the common name), but some range in color from cream to plain white.
The selection of species to plant depends on various factors, such as the soil type, the position (sunny or shady location), the colour or effect that is required and the season of the year when the plants are required to flower. Border of tulips planted among pansies. Some examples of bulbous plant genera and their flowering season are given ...
The plant produces one or more spindle-shaped [5] or cylindrical [11] tubers. The largest may weigh 10 pounds (4.5 kg) and grow one meter (3 ft 3 in) underground. [ 11 ] Dioscorea polystachya is more tolerant to frost and cooler climates than other yams, which is attributed to its successful introductions and establishment on many continents.
