Shoots grow upwards from many different places on the tuber. Examples of tubers are Dahlias, Begonias, Anemones and Potatoes. Corms are actually enlarged underground stems that store nutrients, surrounded by papery outer layers. After stems sprout from the corm, buds form on top of the stem. Corms at their center are solid tissue, whereas Bulbs are immature layers of leaves. At the end of the growing season, a new corm typically grows on the base of the spent one, and plants regrow from new corms each season.
Examples of corms are Gladiolus and Crocus. Rhizomes are stem-like structures that grow horizontally across the ground, forming roots from the bottom while sending shoots upward.
Buds form at different parts along the structure, not necessarily at the top. Rhizomes store nutrients for newly growing plants. A bulb is comprised of a plant's stem and leaves. The bottom of the bulb is a compacted stem, and roots grow from this part of the bulb.
Layers of nutrient-filled leaves sit at the bottom of the bulb and surround a bud that eventually becomes the flower. Examples of bulbs are Tulips, Lilies , and Daf fodils. Whether your plants are growing from a Tuber, Corm, Rhizome, or Bulb, all of these plant structures are sure to produce a spectacular show in the spring and summer months. Happy Gardening!

Borneo Giant Elephant Ear is a monumental cultivar that can reach up to 8 feet tall in its first year and matures to up to 12 feet tall. You can cut off individual hunks that have buds and plant them to get new plants, which is something you can't do with corms and bulbs. An example of a landscape plant that grows from tubers is the Dahlia. Tubers, unlike corms, bulbs, and rhizomes, do not multiply. Still, other plants grow from rhizomes. Rhizomes are modified, swollen stems that grow horizontally.
They often appear as nothing more than roots. Like tubers, rhizomes have buds from which new plants sprout. But tubers do not grow horizontally.
Powerhouse weeds such as Japanese knotweed Polygonum cuspidatum use rhizomes to full advantage, spreading to form monocultures that dominate a landscape. Leave just the smallest scrap of rhizome behind in the soil when trying to dig out such a weed, and it will defiantly return. Lily-of-the-valley Convallaria majalis , Chinese lantern Physalis alkekengi , and Canna lily are examples of landscape plants that grow from rhizomes.

Surrounding the bud are white, fleshy scales that contain all the food the bulb needs. Many true bulbs are protected by a tunic, a thin outer skin.
Onions, tulips, narcissus and lilies are examples of true bulbs. While tubers are a food and energy storage structure like true bulbs, they are very different in appearance.
Tubers are basically enlarged stem tissue and do not have a basal plate or papery tunic. They also come in a variety of shapes and may be flat or cylindrical.
Tubers may also come in clusters. The University of California points out that potatoes, begonias and dahlias are examples of tuber crops. New bulbs often form around the original bulb. These are called offsets and develop from buds within the base of the original bulb to produce new plants. Tubers do not grow from a single point. Instead, the buds — sometimes referred to as eyes — develop over the surface of the tuber, so stems can appear from the sides as well as the ends.
New plants can be grown from tuber cuttings containing buds or eyes, or from seeds.
