Forming thick mats along the shores of shallow water, the invasive, foreign alligator weed has become an all too common sight on Texas shorelines and river banks. The vine-like plants start on shore and creep out to cover the surface of the water.

Cooked alligator weed has a mild, pleasant taste and is a wonderful source of minerals. Treat it like spinach but do not eat it raw. It must be cooked to kill any aquatic parasites. The stems are best chopped up so as to minimize any toughness they might have. The newest growth will be the most tender.

Warning: The water and mud in which it is growing must be free of any harmful minerals or heavy metals as the plant will gather and concentrate these toxic compounds. This accumulating power has been harnessed for bio-remediation of highly contaminated locations.

What: young leaves, seeds
How: Young leaves raw or cooked, seeds eaten raw, roasted or ground into flour
Where: sunny fields, disturbed areas
When: summer
Nutritional Value: Grains supply protein, calories, and minerals. Leaves vitamins A & C along with minerals calcium, iron, and phosphorous, and also fiber.

Leaf Arrangement: The leaves are alternately arranged along the stem.

Leaf Shape: Leaves are generally broad, lanceolate, or ovate, with lengths ranging from 2 to 6 inches and widths of 1 to 3 inches.

Leaf Venation: Pinnate venation exhibits well-defined veins extending from the midrib to the leaf margins.

Leaf Margin: The leaf margin is entire, displaying a smooth and continuous edge.

Leaf Color: The upper surface of the leaves is a vibrant green, while the underside may have a slightly lighter shade.

Flower Structure: Flowers are arranged in dense, elongated clusters called inflorescences, with each flower having a diameter of approximately 1/4 to 1/2 inch. Each flower has three to five petals and is located at the tips of the stems.

Flower Color: Flowers may be green, red, or purple, depending on the species, matching the foliage color.

A variety of amaranth species can be found across Texas and the South. Shapes range from prostrate, creeping vine-like weeds to striking, tall, cultivated forms. The most distinctive feature of all amaranths is their spikes of tiny, clustered flowers which are the same color as the rest of the plant. Amaranths are most commonly found in sunny, disturbed areas and wastelands such as abandoned lots and roadsides. Bright red versions are often included in landscaping.

Amaranth leaves can be eaten raw or used as a spinach substitute in any dish. The leaves are high in vitamin A & C, assorted necessary minerals and also fiber. The youngest leaves have the best flavor and texture, but even the large, old leaves can be chopped up and included in any food needing a vegetable.

Amaranth seeds are very rich in carbohydrates and up to 16% protein by weight. Better still, the seeds contain the amino acid lysine which is very rare for plants but vital for human health. A single plant can produce as many as 100,000 of these wonderful, slightly nutty-tasting seeds. They can be eaten raw but toasting and then grinding into flour releases the most nutrition. The ornamental varieties are just as productive as the wild one but are more attractive. Amaranth seeds have even been used to make a gluten-free beer.

Where: marshes, water
When: tubers all year, best in late fall and early winter; young leaves in early summer; flower stalks well before flower buds have opened.
Nutritional Value: carbohydrates
Dangers: Beware the similar-looking arrow arum, (Peltandra virginica) plant which has an arrowhead-shaped leaf and produces tubers same as Sagittaria species.

Leaf Arrangement: The leaves are alternately arranged along the stem, typically emerging from the water or mud.

Leaf Shape: Arrowhead-shaped (sagittate), measuring 4 to 12 inches long and 2 to 6 inches wide.

Leaf Venation: Venation is palmate, looking like a spider, starting at where the stalk meets the leaf and branching out to the edges of the leaf.

Leaf Margin: Margins are smooth and entire.

Leaf Color: The leaves are generally a glossy green, sometimes with a slightly bluish hue.

Flower Structure: The flowers are arranged in whorls on a spike, with each flower having three white petals and three green sepals.

Flower Color: White, often with a yellowish center.

Fruit: Produces small, round, green fruits that turn brown as they mature.

Seed: Seeds are small, numerous, and contained within the fruit.

Stem: Stems are long, thick, and can be either submerged or emergent, depending on the water level.

Found in marshes, rivers, lakes and ponds, the arrowhead plant’s distinctive leaf and flowers are easy to spot. Most arrowhead plants have three-pointed leaves shape like an arrowhead, with either the top point bigger and broader than or the same as the two downward pointing points. The vein pattern in the leaves of Sagittaria species is palmate, which means the leaves have numerous thick veins running from the stem out to the tips and sides. This pamate venation is important to distinguish the edible Sagittaria from toxic Arum species.

Traditionally arrowroot tubers are freed from the mud by tearing them from the roots while walking barefoot in the water. The tubers float to the surface where the can be collected. They are prepared for eating by first peeling the bitter outer skin, followed by cooking any way you would cook a potato. The young leaves are harvested and boiled before they've had a chance to unroll/unfurl. The flower stalk is cooked like asparagus but it must be harvested before its flower buds have opened. Note, any plants harvested from water must be cooked to avoid imbibing any toxic pathogens.

Note that arrowhead tubers do not store very well, unlike traditional potatoes. If you want to keep them make sure you are storing only perfect, undamaged tubers and place them in moist, clean sand in a cool, dark place.

Young, still curled leaves that are either above or below the surface of the water make an excellent cooked green. Treat them like spinach. The young flower stalk before the flower buds appear can be used in the same manner as the leaves.

TOXIC MIMIC: ARROW ARUM PLANT
Arrow arum plants (Peltandra virginica) grow in wetlands, and have a leaves-with the same arrowhead-shape as the edible Sagittaria, as well as similar tubers. All parts of the arum plants are filled with calcium oxalate which will cause painful burning sensations in the lips, mouth, and throat if eaten. To tell the difference between arrowhead plants and Arum arrowhead plants look at the pattern of veins in the leaves. Toxic arrow Arum leaves have only three main veins, one each running out from the center out to the points of its leaf. From these three main veins branch out smaller veins, much like you see in a "normal" leaf of other plants. The edible arrowhead leaf has many veins radiating out from the center of the leaf where it connects to the stem, making it kind of look like a spider. These veins meet up again at the tips/points of the Sagittaria leaf.

Bamboo/River Cane

Scientific name: Arundinaria gigantea
Abundance: uncommon
What: seeds, young shoots
How: cooked/steamed
Where: river banks above high-water level
When: early spring through summer
Nutritional Value: small amounts of carbohydrates, protein, and vitamin C
Other uses: fishing poles, lattice structures, blow guns
Dangers: beware of deadly purple Ergot fungus.

Leaf Arrangement: Alternate, with each leaf spaced out along the culm (stem), which is characteristic of many grass species.

Leaf Shape: Lanceolate and elongated, typically 8 to 12 inches long and 1 to 2 inches wide.

Leaf Venation: Parallel venation is prominent, running the length of the leaf from base to tip.

Leaf Margin: Margins are serrulate, with fine teeth along the edge that are perceptible to touch.

Leaf Color: The foliage is a deep green, often turning yellow-green in fall.

Flower Structure: Inflorescences are panicles, branched and open, appearing terminal on the culms.

Flower Color: The small, individual flowers within the panicles are not showy, usually green or brownish.

Fruit: Produces a caryopsis, a grain typical of the Poaceae family, though fruiting is infrequent.

Seed: Seeds are small, enclosed within the dry fruit, and not commonly harvested or seen.

Stem: Known as culms in grasses, they are hollow, erect, and can reach heights of up to 25 feet. Interior is hollow between leaf nodes. Young sections of the culm will be green whereas older parts will be yellowish or brown.

Hairs: Young shoots may have a coating of fine hairs, which becomes less noticeable as the plant matures.

Height: Mature stands can range from 10 to 25 feet in height.

Once thick canebrakes used to be found along many Texas streams where they formed their own distinctive ecosystems. Over-grazing by cattle, who love the leaves, along with other habitat destruction has greatly reduced these canebrakes, leading to the loss of certain species of warblers which nested exclusively in the safety of these bamboo stands. Their scientific name suggests that this bamboo can grow to gigantic sizes but in truth they rarely get over ¾” thick and more than 9’ tall.

Tender river cane shoots of any size can be eaten raw or used in stir-fries and other Asian-style dishes. Firmly grab the top of the cane and pull. Usually whatever comes off is tender enough to eat but nibble the bottom end to make sure it isn’t too hard or fibrous. Peel off and discard the leaves or use them to weave tiny baskets. I like the youngest shoots, less than three inches tall growing from what looks like clumps of grass.

River cane makes excellent fishing poles. They were also used by Native Americans to make baskets, arrows and blowguns. Some of you more mature plants probably received a whack or two from a rivercane after misbehaving.

River cane is slightly susceptible to ergot fungal infections. Closely examine any river cane for signs of a purple powdery substance before harvesting, especially during rainy summers following very cold winters. Ergot poisoning can lead to hallucinations followed by death. I have yet to find any river cane infected with ergot, but I still keep an eye out for this fungus.

Basswood/Linden

Scientific name: Tilia americana
Abundance: rare
What: flowers, leaves, buds, inner bark
How: leaves raw in salad, buds to nibble, flowers for tea, cambium (inner bark) raw or boiled for calories
Where: Sunny edges of woods
When: buds in late winter, young leaves spring/summer, flowers summer, cambium all year
Nutritional Value: Leaves contain vitamins and minerals, inner bark has carbohydrates
Other uses: cordage from bark, not a good firewood

Leaf Arrangement: Basswood trees typically have alternate leaf arrangement along the branches.

Leaf Shape: Leaves are generally large, heart-shaped, with lengths ranging from 4 to 6 inches.

Leaf Venation: Prominent veins are visible on the leaves, contributing to their overall structure.

Stem Characteristics: The stems are usually slender, and the trunk can reach diameters of 2 to 4 feet.

Flower Cluster: Basswood trees produce fragrant, pendulous clusters of small, pale-yellow to cream-colored flowers in late spring or early summer.

Flower Structure: Individual flowers are small and have five petals. Flowers can be around 0.2 to 0.3 inches in size.

Seed: The seed is enclosed in a papery wing, forming a structure known as a samara. The wings can measure around 1 to 2 inches in length, looking like a leaf. A several seed capsule pairs, all branching from a single stem, dangle down from the leaf-like wing.

Seed Characteristics: Seeds are small and brown, typically located at the center of the samara.

Height: Basswood trees can reach heights of 60 to 80 feet, with variations based on age and growing conditions.

Bark: The bark of young trees is smooth and light gray, becoming more furrowed and darker with age. Bark color can range from light gray to dark gray-brown.

Hairs: Young shoots and leaves may have fine hairs, but mature leaves are generally smooth. Inspect young shoots and leaf undersides for pubescence.

Fruit: The fruit consists of the winged samaras, which are produced in clusters as described above, and become tan to light brown as they mature.

Stately basswood trees range from 60 to 120 feet tall with shallowly-furrowed, somewhat greyish bark and round crowns. There are thirty species in North America with Tilia Americana and Tilia caroliniana being the most common in Texas. Basswoods prefer loose, well-drained soil with access to moisture, in particular river flood-plains and in low areas of woods.

The sweet sap, running in the spring before the leaf buds open, can be boiled down into a syrup or just drank as-is. Be sure to sterilize your tools before using them to cut or drill into the tree to collect sap or inner bark. This reduces the chance of a fungal infection striking the basswood.

A very delicious, spicy tea is made from the small flowers of basswood trees, which appear in the spring. The flowers can also be eaten raw. Bees love these flowers and often the tree can be found just by listening for the buzz of the hundreds of bees collecting its nectar. The resulting honey has a flavor imparted from the basswood nectar.

The young leaf buds and leaves can be eaten raw and have a slightly sweet flavor similar to the flowers. These parts can also be cooked like pot-herbs.

In the fall the nuts make a good trailside nibble while hiking, but only eat the inner meat, not the nuts’ outer shells.

The calorie-rich cambium layer, just under the bark, is stripped, finely diced, and boiled into a porridge-like mush to eat any time of the year. In Europe towards the end of World War II basswood sawdust was added to bread to try and produce enough loaves to fill everyone’s belly.

This cambium layer can be used to make strong fibers that can be woven into rope, containers and crude cloth. This inner bark must be soaked for up to two weeks to rot away the majority of the plant’s cells, leaving behind just the fibers. The wood itself is great for carving and for making the body of guitars.
