Across fields and disturbed areas of Texas and the South, Balloon Vines are taking hold. Keep an eye out in sunny fields, especially along ditches and other areas where water may collect. Balloon vines are easily spotted by their small, puffy, pointed seed pods. These pods are mostly air with the fruit located in the center. If the weather stays warm these vines can produce these balloon-like seed pods all year long so you may see white flowers, young, green pods, and dried, brown pods all on the same vine.

Balloon vines are an invasive species from Asia and can quickly cover and kill native plants. This makes a good argument for eating them! The edible parts are its young leaves and vine tips. These are cooked before eating, though to be honest I don't know why. That's how they do it in Asian countries, which is a good enough reason for me.

The puffy seed pods are not eaten, nor are the seeds contained in these "balloons". However, both the leaves and seeds were used medically in India and Asia, along with the roots. Leaf poultices were used on skin wounds and infections as well as minor muscle and joint problems like strains, sprains and arthritis. Tea made from the leaves was traditionally used against stress and bronchitis. Tea from the root was applied topically to treat hemorrhoids. The seeds were crushed for a tea given to relieve fevers and joint pain.

There's a yellow-flowered invader lining the roadsides and taking over fields of Texas and the rest of North America and it's name is Bastard Cabbage! Wow, that was a lot of "and"s in that previous sentence. Oh well. These plants prefer cool weather, fall through spring, during which time they're unfortunately everywhere. On the plus side, being a member of the brassica (mustard) family, pretty much all parts of this invader from southern Europe are edible.

Starting at the top and working our way down the plant, it's flowers have the standard mustard-family structure of four petals (yellow in this case) in an "X" arrangement surrounding six stamens, four of which are long and two stamens are short. The flowers grow in bunches off the stem and before they blow the highly-packed clusters look like tiny heads of broccoli, which is also a member of the mustard family. Below the flowers are seedpods arranged in a spiral up the stem. Note the "beak" jutting out from the top of the seedpod away from the stem.

The stem itself is somewhat hairy branched. The leaves at its base are large, broad, deeply lobed, and form a rosette whereas the leaves closer to the tops of the stems will be elongated, narrow, and unloved or very shallowly lobed. Underground, bastard cabbage forms a heavy taproot, similar to that of horseradish.

How do I eat this invasive species? The flowers and green seedpods I like raw straight off the plant or added to salads. The broccoli-like flower buds are also eaten raw or cooked like broccoli florets (drizzled with cheese!) The younger, tender leaves are cooked like turnip/collard greens, sautéing them with some garlic and bacon. The younger, tender parts of the stem do well when cooked/steamed like asparagus. I have yet to experiment with the roots but suspect a low-grade "horseradish" sauce could be made from them.

Bittercress pops up when most everything else is brown. Look for it yards, flowerbeds and assorted border areas where low growing plants aren't swallowed up by taller stuff. I've been known to buy a potted plant on clearance just because it had some nice bittercress growing in the pot.

Bittercress comes up with a rosette of deeply lobed leaves and small, white flowers which twist up the stem like a spiral staircase. After the flowers come long, thin seedpods which explode open on touch once they've matured and turned brown.

Bittercress has a wonderful horseradish flavor that is great for spicing up sandwiches and salads. The young leaves can be eaten raw while older, larger leaves can be cooked like traditional mustard greens. The seeds are too small to be ground into a mustard-style condiment but the tender, young seedpods are as good or better than the young leaves for a raw blast of flavor.

The leaves and seedpods must be chewed for a bit for the full, powerful flavor to develop. Their taste doesn't come from chemicals found in the plant but rather from the product of these chemicals as they undergo a reaction initiated by chewing. Chewing smashes the cell walls, releasing the compounds so they can react with the oxygen and water in your mouth, resulting in the excellent horseradishy punch.

Standing up to 125’ tall with a rounded crown, black walnut trees cut an impressive figure across the fields of Texas. They prefer open, sunny locations but can also be found in forests. Black walnut leaves are compound with an even number of leaflets and being deciduous, drop off in the fall. The bark is grayish, dark and deeply furrowed/rough. The round nuts of this tree are contained in a thick, green cover which begins to splits open when ripe. The juice of this green coat smells like iodine and will stain skin and cotton fabric brown. Black walnut tree leaves, bark, and nut husks contain a poison which kills most other non-grass plants so do not add these materials to compost piles. The wood of black walnut trees is treasured by woodworkers and commands a premium price. This has led to many incidents of “tree rustling” where huge, old trees are cut down and stolen.

The nuts become ripe in the fall. Peeling the green husk is staining so wear gloves and avoid letting the peels come in contact with anything you don’t want turned brown. The thick shell of the walnut is very hard and most standard nut crackers can’t crack them. Waiting a few weeks after removing the husk allows the nuts to dry some, making shelling them slightly easier. The usual method of shelling black walnuts is to run over the nuts with a car followed by picking apart the shell with a nutpick. If you only have a few nuts they can be broken open with a hammer. If you have a lot of nuts it may be worthwhile to invest in a manual cracker specifically designed for black walnuts. Black walnuts have a stronger flavor than English walnuts so most people reduce the amount of nut meat used by one half in recipes.

The crushed green husks were used by Native Americans as a fish poison. Several large, woven bags of these husks were placed in a still pond or weir and the chemical juglones would seep out and stun the fish, causing them to float to the surface.

When the nuts are still green and soft enough to cut in half with a knife they can be pickled and then blended not a ketchup-substitute. As they get bigger the still-unripe notes can be soaked in vodka with a bit of lemon peel, cinnamon, star anise, and sugar syrup to create the Italian liquor "Nocino". Black walnut trees grow farther south than maples and though they produce only about 1/4 as much sap as maples, the resulting syrup made by boiling the sap down is quite delicious.

Never plants a Black Walnut near a garden as the roots, twigs, and leaves all produce a toxin which kills many other plants. Native grasses seem to resist this poison better than domesticated, decorative or food plants. My mom still nags me about the black walnut seedling I planted at the edge of her garden which eventually grew tall and wiped out a quarter of her crops even though this happens 30 years ago.

Holy crap!!

Usually found in sunny, loose-soiled fields and other disturbed areas, these small, leggy bushes rarely grow more than two feet tall. The stinging hairs which cover bull nettle stems, leaves, and fruit offer a great protection against man and beast. While the pain they inflict is fierce, it often lasts less than an hour. The white blooms begin appearing in early spring and continue on through mid-summer. The green seed pods track the flowers by about a month.

Strangely enough, bull nettles are often commonly found growing near sassafras trees in Central and East Texas woods such as the Sam Houston National Forest. Bull nettles prefer full sun so finding them in the woods is odd, especially only in the presence of sassafras. Perhaps the sassafras root system both loosens the soil and releases some chemical which aids the bull nettles growth.

This plant, though armed with a similar defensive mechanism, is not related to stinging nettle. It's leaves are not edible in any way.

Harvesting the delicious seeds is best done using BBQ tongs or thick leather gloves to remove the seed pods from the plant. Then place these pods in a brown paper bag and wait a while (days). The pods will dry and then rupture, releasing the seeds which can then be toasted for a wonderful treat. The roasted seeds can also be pounded/ground into something similar to cornmeal and used in the same manner.

Digging up the taproot can be tricky. First, carefully cut away the top part of the plant with a machete or other long blade, then dig a hole 18" deep approximately one foot away from the stem of the plant. Carefully shave away the soil on the plant-side of the hole until you see the earth-colored root. At this point carefully remove the dirt from around the fragile root until you can lift it from the soil. Peel the root and then either roast or boil it like a potato. It will retain a bit of firmness rather than turning as soft as a potato. Through the root’s center runs a strong fiber core which needs to be discarded.

Carolina Geranium

Scientific Name(s): Geranium carolinianum
Abundance: common
What: roots
How: medicinal
Where: yards, fields
When: winter, spring
Nutritional Value: none (not edible)
Dangers: Carolina geraniums are NOT edible but are only used externally medicinally in wounds and gargles, do not swallow.

Medicinal Summary:
Root - astringent; antibacterial; anti-fungal; soothes sore throat/mouth; anti-diarrheal (poultice, powder, tisane)
Whole plant - pain reliever, fever reducer, anti-inflammatory (tisane, tincture)

Leaf Arrangement: The leaves of Geranium carolinianum are arranged in a basal rosette. This means the leaves primarily grow at the base of the plant, close to the ground.

Leaf Shape: The leaves are deeply lobed, giving them a somewhat cut or dissected appearance. Each leaf typically has 5 to 7 lobes.

Venation: The venation is palmate, meaning the veins radiate outward from a single point like the fingers on a hand.

Leaf Margin: The margins of the leaves are crenate, meaning they have rounded teeth.

Leaf Color: The leaves are generally green, but they may have a hint of red or purple, especially in cooler temperatures.

Flower Structure: The flowers have five petals and are arranged in loose clusters. Each petal has a small, rounded notch at the tip. Individual flowers are about 1/5" across.

Flower Color: The flowers are usually light purple to pink, sometimes with darker veins.

Fruits: The fruit is a beaked capsule, which when mature, splits open to release seeds. The 'beak' of the capsule resembles a crane's bill, hence the common name 'Cranesbill.'

Seeds: The seeds are small, oblong, and generally have a reticulated surface.

Stems: The stems are erect to ascending, and can be hairy. They are typically green, but like the leaves, may have reddish to purplish tinges.

Plant Height: This plant usually grows to a height of about 10 to 18 inches.

Hairs: The stems and sometimes the leaves are covered in small hairs, which can give the plant a slightly fuzzy appearance.

Many a yard, flowerbed and garden see this low, creeping weed show up in the Texas "winter". Left unpacked, it'll turn into a leggy, small bush around one foot tall and two feet across. The leaves are deeply lobed with rounded, toothed edges. Stems are hairy. The pink flowers eventually turn into a long, pointed seedpod thingy. The plant grows outwards from a single taproot and that taproot is the medicinal part that you'll want. The bigger the aboveground plant the bigger this root so put off harvesting it as long as possible.

The root of Carolina geranium is very astringent which makes it excellent for stopping bleeding. Astringent compounds cause capillaries to constrict, thereby shutting down minor bleeding. If you're spraying arterial blood or have a deep slash through several medium-to-large veins you're out of luck. Think nosebleed level of bleeding or smaller. Dry/dehydrate the plant, grind it into powder, then keep stored in an airtight container. Apply this power to a cut/slash to control bleeding.

These astringent molecules will also give some relief to a sore throat if gargled but don't swallow the decoction made from the root. After a minute of swishing/gargling spit it out. To use this root as a gargle/mouthwash, simply pull it out of the ground and rub/rip away the small, side roots from the main taproot. You can use it fresh if you chop it up really finely then boil 1-2 teaspoons full in 1 cup water for ten minutes. My lawyer says I need to remind people to let this solution cool before using. Native Americans would dry the root, grind it into a fine powder, then sprinkle this powder into wounds to stop bleeding. Personally, I've never tried this powdered root method but hey, it might be good to know when the zombies come.

Two mimics of this plant are the poisonous Creeping Buttercup (Ranunculus repens) and edible Carolina Bristle Mallow (Modiola caroliniana).

Poisonous mimic Creeping Buttercup (Ranunculus repens).


You can see the leaves of the creeping buttercup are much less deeply lobed, shinier, and smoother. The stems are smooth and the entire plant hugs the ground more closely than Carolina geraniums. Creeping buttercups contain a chemical that, when consumed, makes mammals hypersensitive to sunlight. Skin hit by sunlight almost immediately starts to blister...basically, creeping buttercups turn you into a redhead!

Edible Carolina Bristle Mallow (Modiola caroliniana).


Carolina bristle mallow has very coarse leaves and stems. It creeps along the ground and puts down roots wherever the stem touches the ground. It is used to make a cooling tea.
