Plant stems have a variety of functions. Stems support the entire plant and have buds, leaves, flowers, and fruits. Stems are also a vital connection between leaves and roots. They conduct water and mineral nutrients through xylem tissue from roots upward, and organic compounds and some mineral nutrients through phloem tissue in any direction within the plant. Apical meristems, located at the shoot tip and axillary buds on the stem, allow plants to increase in length, surface, and mass. In some plants, such as cactus, stems are specialized for photosynthesis and water storage.
Modified stems
Typical stems are located above ground, but there are modified stems that can be found either above or below ground. Modified stems located above ground are phylloids, stolons, runners, or spurs. Modified stems located below ground are corms, rhizomes, and tubers.
The edible portion is stem tissue. The fig "fruit" is actually an inverted flower cluster with both the male and female flower parts enclosed inside the base of the inflorescence, corresponding to the peduncle.
The edible portion is a rhizome (an underground stem) that is also a tuber. The "eyes" of the potato are lateral buds. Potatoes come in white, yellow, orange, or purple-colored varieties.
The edible portion is the inner stalk (stem) whose sap is a source of sugar. In its raw form chewing or extraction through a juicer extracts its juice.
The sweet inner bark (phloem) was eaten by Native Americans.
Some wild plants with edible stems
There are also many wild edible plant stems. In North America, these include the shoots of woodsorrel (usually eaten along with the leaves), chickweeds, galinsoga, common purslane, Japanese knotweed, winter cress and other wild mustards, thistles (de-thorned), stinging nettles (cooked), bellworts, violets, amaranth and slippery elm, among many others. Also, some wild plants with edible rhizomes (underground, horizontal stems) can be found, such as arrowhead or cattail. Wild edible stems, like their domestic relatives, are usually only good when young and growing. Many of these also require preparation (as do many domestic plants, such as the potato), so it is wise to read up on the plant before experimenting with eating it.
