Edible plant stems are one part of plants that are eaten by humans. Most plants are made up of stems, roots, leaves, flowers, and produce fruits containing seeds. Humans most commonly eat the seeds (e.g. maize, wheat, coffee), fruit (e.g. tomato, avocado, banana), flowers (e.g. dandelion, broccoli, lavender), leaves (e.g. lettuce, spinach, and cabbage), roots (e.g. carrots, ginger, beets), and stems (e.g. asparagus, rhubarb, leek) of many plants. There are also a few edible petioles (also known as leaf stems) such as celery.

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[edit]

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 crowns, stolons, runners, or spurs. Modified stems located below ground are bulbs (which are actually primarily the enlarged base of the plant's leaves), corms, rhizomes, and tubers.

Detailed description of edible plant stems[edit]

Crispy lotus stem garnished with chives
The edible portion is the rapidly emerging stems that arise from the crowns in the
The edible portion is the young shoot (culm).
Trunk sap is drunk as a tonic or rendered into birch syrup, vinegar, beer, soft drinks, and other foods.
The edible portion is stem tissue, flower buds, and some small leaves.
In addition to its edible root, its leaves and stems may also be eaten. They may be blanched to remove their bitter taste.
The edible portion is proliferated stem and flower tissue.
The whole plant is edible including the crisp petiole (leaf stalk) and the fleshy taproot.
Stems of chives have a mild flavor.
Many favor the unique sweet flavor of the inner bark of cinnamon, and it is commonly used as a spice.
The stems taste mildly bitter.
The edible portion is stem tissue. The fig "fruit" is actually an inverted flower with both the male and female flower parts enclosed inside stem tissue.
The edible portion is predominantly swollen leaves with a bit of stem.
Ginger root 
The edible portion is a branched underground compressed stem also referred to as a rhizome.
The edible portion is an enlarged (swollen) stem. It is a member of the cabbage family and is white, green, or purple in color.
Similar to other members in the onion family, the edible portion is swollen leaves with a bit of stem.
Lotus root 
The edible portion is a stem modified for underwater growth. Buds and branches are visible on the vegetable sold as lotus root.
The edible portion is stem segments.
The edible portion is swollen leaves with a bit of stem. They are bulbs which, like garlic and leeks, are modified stems in which the primary storage tissue is expanded leaf bases. They come in white, yellow, and red varieties.
The edible portion is 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 whole plant is edible, but it is commonly grown for the root.
The red or green stalks are the edible portion; the leaves are toxic.
The shoots and stem bark are sometimes used to make root beer.
Also a member of the onion family, the edible portion is mainly swollen leaves with a bit of stem.
Sugar cane 
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.
Sugar maple 
Phloem sap from the tree trunks is made into maple sugar and maple syrup.
The edible portion is the underground stem (corm).
In addition to its edible stem, the leaves and rhizomes of the plant are edible. Its unique spicy taste has led it to become a common addition to Asian cuisine.
White pine 
The sweet inner bark (phloem) was eaten by Native Americans.

Some wild plants with edible stems[edit]

There are also many wild edible plant stems. In North America, these include the shoots of common milkweed, Solomon's seal, woodsorrel (usually eaten along with the leaves), blackberry and raspberry (peeled), chickweeds, galinsoga, common purslane, Japanese knotweed, saxifrage, cleavers, wild leeks, wild onion, nodding onion, field garlic, wild garlic, winter cress and other wild mustards, thistles (de-thorned), stinging nettles and wood nettles (cooked), burdock, bellworts, jewelweed, spiderwort, violets, carrion flower, twisted-stalk, amaranth, pine and slippery elm, among many others. Also, some wild plants with edible rhizomes (underground, horizontal stems) can be found, such as cattail, ground nut, Solomon's seal and false Solomon's seal. Wild edible tubers include arrowhead, and many more. 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.
