Burr Clover

Scientific Name(s): Medicago polymorpha
Abundance: plentiful
What: seeds
How: raw or roasted, ground into flour
Where: sunny fields, lawns, and neglected areas
When: late winter through summer
Nutritional Value: starch

Leaf Arrangement: Leaves are alternate arrangement where each leaf emerges individually at different points along the stem.

Leaf Shape: The compound leaves are trifoliate, meaning each leaf is composed of three leaflets. These leaflets are obovate to oblanceolate in shape, broader at the tip and narrowing towards the base.

Venation: It exhibits pinnate venation, with a central vein in each leaflet and smaller veins branching off to the sides.

Leaf Margin: The margins of the leaflets are toothed, especially near the tip.

Leaf Color: The leaves are generally a bright green color.

Flower Structure: The flowers are small and grouped in tight clusters. Each flower is typical of the pea family, with a banner, wings, and keel.

Flower Color: The flowers are yellow.

Fruit: The fruit is a coiled pod that resembles a burr, hence the name burclover. It often has spines or hooked hairs.

Seeds: Each pod contains several small, kidney-shaped seeds.

Stem: The stems are slender, can be either prostrate or ascending, and are often branching.

Hairs: The plant, especially the fruit, may have small hairs or spines.

Height: Medicago polymorpha typically grows to a height of about 6 to 24 inches, depending on environmental conditions.

Burr Clover is often mistaken for regular clover but these leaves are coarse, rough-edged and grow off prostate runners all branching out from a central taproot. The edible seeds grow one per seedpod and can be eaten raw or roasted then ground into flour once they turn black.

Being mostly starch, it should be possible to use Burr Clover seeds to produce alcohol. The starch must be broken down into simple sugars for the yeast. The easiest way to do this to combine the crushed seeds with the amylase enzymes found in saliva…in other words, the traditional “spit beer” made by many primitive cultures where a starchy material is chewed and then spit into a large pot to ferment for several days to produce a weak alcoholic drink. Luckily, high concentrations of the necessary enzyme are also found the sprouts of barley and other grains, which can be bought from brewer supply stores.

Like most clovers, Burr Clover forms a symbiotic partnership with rhizobium bacteria which allows it to turn atmospheric nitrogen gas into a form usable by plants. This makes it a beneficial plant to let grow in your garden as it fertilizes nearby plants with this nitrogen.

Spring up uninvited just about anywhere some bare, fertile soil waits, black nightshades with its tiny white flowers, clusters of black berries, and small leaves can grow 3’ to 4’ tall and just as wide between spring and the first frost of winter.

The leaves are lanceolate or elliptic in shape with smooth edges. Looking closely at the flowers, the petals are revealed to be folded backwards, an indication you are looking at the mellow-flavored Solanum ptychanthum aka American nightshade. The berries of this plant start out green with white spots but quickly turn black and edible. Birds love these berries which is why the plant quickly gets spread far and wide via bird poop. You'll find flowers, unripe berries, and ripe berries all at the same time on a single plants as it continuously produces its tiny fruit all summer long.

The main edible portion of Solanum ptychanthum are its leaves which I love cooked in curry sauce then poured over chicken and rice. Time spent with the amazing forager, Sam Thayer, revealed the young, tender leaves are a fine, raw addition to salads. That being said, it's still safest to cook the leaves, especially if you aren't used to eating lots of wild plants. 

The very similar-looking Solanum nigrum is one of the most popular vegetables of Asia and Southern Europe yet here in North America, where it has naturalized, it is lumped in with its much more poisonous family members such as belladonna. Its green, immature berries do contain solanine but the ripe berries are safe to eat. My preferred way of preparing them is baking in muffins and pies.

Blackberry brambles seem to line every roadside, abandoned wasteland, field edge and stream bank in East, Central, and Gulf Coast region of Texas. Other Texas regions also have them if enough water is present. The thorny blackberry canes makes passing through these plants a painful experience. Even the petioles of the leaves can have these spines. The canes begin producing new leaves in late winter, followed by many white flowers in March-April. The appearance of these flowers in Houston tell me it's time to do my taxes! The berries appear 6-10 weeks after the flowers. By mid-summer the blackberry canes will be brown and dried, seemingly dead though if the summer is mild the'll last into the fall.

A delicious tea can be made from blackberry flowers and/or its young leaves. I recommend using the leaves rather than flowers so as to not reduce the amount of fruit produced. For tea, pick young healthy leaves in late morning after any dew has dried but before the sun has had a chance to evaporate the volatile flavoring oils out of the leaves. Dry the leaves before use for a richer flavor. Keep the pot or mug covered so the volatile flavors stay in the tea rather than float out into your kitchen. The combination of blackberry and Yaupon holly leaves makes a most excellent and vitamin-rich tea rich.

The more sun and water the berries get the bigger and sweeter they will be. In dry or cloudy years or if growing in shady areas the berries will be small and tart. Blackberries will be at maximum ripeness when they are swollen and flat black. Shine black fruit are not quiet ripe yet and so won’t be at their maximum sweetness. These berries are fantastic raw, made into jelly, jam, or wine, boiled down into a syrup, made into cobbler or mixed into ice cream. Seriously, any dessert you have in mind can be made with blackberries!

An individual cane will only bear fruit in its second year. Once you've harvested the cane’s berries cut and dispose of the cane to make next year’s berry harvest easier. Beware of snakes and fire ant mounds hidden by the thick brambles as you pick the berries.

The technical name for this type of plant structure is a "cane" but I put it under "Vine" to make it easier to find by beginners.

Boneset is a rather unique and easily identified plant. Appearing in the summer, there stiff, straight, hairy stems grow up to about four feet tall, with some branching occurring in the last foot or so. The really distinctive feature is its leaves. These long, narrow, pointed leaves are opposite each other on the stem but their bases fuse together so as to look like the stem grew through the center of an almost canoe-shape leaf. These dark green leaves are almost shiny but wrinkly on top and their undersides are mildly hairy. The edges of the leaves are toothed and the veins are pinnate with branching of the secondary veins of the main, center vein. In late summer the ends of the stem and branches have clusters of many white, hairy flowers, each about 1/4 inch across.

Look for boneset in low, damp, sunny areas such as roadside ditches and along creeks, or next to ponds in fields. Goldenrod is often nearby. They can also be found growing along moist borders of woods, with hardwoods being a more likely companion than pines.

Boneset is used medicinally rather than as a food but is NOT okay for pregnant women. Boneset tea made from the flowers and leaves helps induce sweating, helps break fevers, and relieves respiratory problems of head colds and other illnesses, including coughing. It helps with inflammations, easing some of the pain of rheumatism and arthritis. The bitter flavor of the tea also stimulates the digestive juices, triggering hunger in someone who hasn't been wanting to eat. As mentioned in the Dangers at the top of the page, due to low concentrations of some toxic compounds, limit your intake to three cups of the tea per day, made with 1/2 teaspoon of dried boneset leaves and flowers. A tincture can also be made from boneset and 80-90 proof alcohol. Boneset tinctures should be taken 1-4mL up to three times a day.

Used often as a decorative landscaping tree, the striking red blossoms of the bottlebrush tree offer more than visual beauty. Their aroma is invigorating, somewhat minty or menthol in nature. The trees are small, rarely more than 15' tall and equally as wide. The leaves are evergreen and the blossoms also last can be found on the tree almost all year round. These flowers really explode vigorously in mid-spring and are often swarmed with bees who know a good thing when they smell it!

Both the flowers and leaves can be used to make an aromatic tea. The fresh blossoms do give a sweeter flavor than leaves. Aging the harvested leaves for two weeks helps as this breaks down the cell walls, allowing more of the flavorful compounds to escape into the tea. Flowers, being more delicate, do not benefit any from being aged and ideally are used fresh off the tree.

You can also use the leaves and flowers of the bottlebrush tree similar in manner to bay or rosemary leaves. Add several to a sauce, stew, or roasting meat to add an exotic flavor.

Mashed bottlebrush leaves rubbed on the skin is reported to keep away insects. This property may also be used to keep clothes, bedding, and houses bug free by laying sprigs of the leaves around whatever you want protected.
