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.

Leaves - stimulate healing of sprains, strains, and broken bones (poultice)

Leaf Arrangement: The leaves of Boneset are arranged in pairs along the stem in a way that makes it appear as if the stem pierces through the center of each leaf.

Leaf Shape: Boneset leaves are lance-shaped, measuring about 3 to 6 inches in length and 1 to 2 inches in width.

Leaf Venation: The venation of Boneset leaves is pinnate, with prominent central veins and smaller branching veins.

Leaf Margin: The leaf margins are serrated with toothed edges.

Leaf Color: The leaves are typically medium to dark green, with no significant color variation between the top and underside of the leaf.

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.

A large part of my childhood was spent up among the branches of the giant Box Elder tree in our backyard. Well, it seemed like a giant tree when I was a kid. These amazingly fast-growing trees max out around 70 feet tall and 30 feet wide. The wood is weak and any big winds will cause branches to drop including those greater than one foot in diameter. Never park under a Box Elder in a storm! These damaged areas quickly lead to the inner heartwood rotting away, making it popular with assorted birds, mammals, and bugs. They do not handle the full Texas sun well, preferring to grow in the partial shade of other trees. They fairly common in East Texas, much less common in the Hill Country and North Texas, and rare to non-existent in West Texas

Box Elders have thick, coarse bark when mature and compound leaves. Both these features hide the fact that they are in the maple (Acer) family. Being maples, they can be tapped for sugary sap in the late winter. Complete directions for tapping maples for syrup can be found here: Making Maple Syrup & Sugar.

Come the warmth of spring, many Box Elder seedlings will sprout up. These are tasty treats to deer, rabbits, and humans! Get them when they are still tender and under eight inches tall. It will have a green, smooth bark and three-part leaves. Actually, the young seedlings look a bit like Poison Ivy to the untrained eye so make sure you know what you are eating. The first set of side leaves of Box Elder are symmetrical whereas Poison Ivy side leaves are asymmetrical with "thumbs" pointing away from the center leaf. The second set of Box Elder leaves will have asymmetrical "thumbs", similar to Poison Ivy.

The inner bark of these trees, like other maples, are edible and contain a fair amount of carbohydrates. Finely chop this inner bark then boil it. Be sure to drink the water to get all the calories. This boiled bark will be a bit sweeter than most other non-maple barks but a flavoring agent will help improve its taste. This inner bark is available all year long though its sugar-content will be highest in the later winter when the sap is flowing.

Box Elder seeds are, in my opinion, the best part of the tree. They grow in "helicopter" shells with two joined together at the stem. Come fall, the ripe shells will break apart and fall spinning to the ground. This fluttering motion will send them a small distance from the mother tree. Treat these seeds like pumpkin seeds except they must be freed from their helicopter shell before boiling them for ten minutes in salt water then salting and roasting them at 400F for 10-20 minutes. Cooking time depends on how crisp you want the final product.

Nose and eye find this plant at nearly the same time. The large, heart-shaped leaves and yellow, 5-petaled flowers of Buffalo Gourd give off an unpleasant smell which reminds me of nasty gym socks. Starting in mid-summer the fruit appear. Looking first like small, round watermelons these fruit eventually turn more yellow as they mature but never grow bigger than a baseball. Buffalo Gourd vines can stretch many yards from a central taproot and the beings perennials, show up in the same spot year after year. It's large taproot makes the plant very drought resistant and it grows best in the drier areas of Texas, especially in the Hill country and westward.

The flowers, similar to squash blossom, can be eaten both raw and fried. They do have a bad odor and are somewhat bitter when raw.

Buffalo gourd seeds were a staple food of early Texas Native Americans. The seeds must be completely cleaned of any gourd flesh or else they will be extremely bitter. Once completely cleaned they can be boiled and mashed into a porridge or roasted like pumpkin seeds and have a similar flavor. These seeds do contain a large amount of calories in the form of oil (25-42%) as well as a significant concentration of protein (22-35%).

The large taproot of Buffalo Gourds were to be strong medicine by Native Americans. These roots were used internally as a tea and also externally in poultices. Due to the high concentration of saponins and other potent chemicals healing with this root should only be tried under the direction of a trained herbalist!

Saponins are found in both the plant's root and in the skin of the gourds and are capable of producing a lather when vigorously combined with water. Because of this they were used as a soap substitute.
