Stately oak trees can grow over 100’ tall and hundreds of feet in diameter under ideal conditions. Their bark ranges from smooth to deeply fissured. Branches tend to give oak trees a round or oblong shape. They usually prefer full sun and loose, well drain soils but with fifteen different species to choose from in Texas along, there’s a good chance you’ll find an oak somewhere nearby.

The calorie-laden acorns of oaks have supplied fats, oils, and protein to mankind for thousands of years. A one ounce (28.3g) serving of shelled acorn meat contains about 110 calories in the form of 6.8g of fats and 1.7g of protein, plus a small amount of calcium. Acorns can be ground into a gluten-free, high-protein flour good for making flat breads and batter-style baked goods as well as to thicken stews and to make gravy. Roasted acorns have been used as a substitute for coffee grounds, but all that can be said about that is the resulting liquid is brown and bitter, any similarity to it and coffee is strictly due to the desperation of the brewer.

Acorn must have their tannic acid leached out before consumption. Luckily tannic acid is very water-soluble and easy leach out by placing the shelled, crushed nuts in a mesh bag then submersing them in running water for several days. An easier method is to coarsely chop them in a blender or food processor then repeatedly running them through a coffee maker until they no longer taste bitter. The hot water will extract the tannins but do not allow the acorns to cool between flushes or the tannic acid will bind more tightly to the acorn meat. Also, do not grind the acorns finely before leach them as a flour-sized particles will clog the filter.

Unfortunately, the fats and oils in acorns turn rancid fairly quickly. Fresh ground acorn flour will go bad in as little as four weeks if exposed to air and warm temperatures. Freezing the flour, especially if vacuum-packed (a messy process) can stretch its usable life to six months. You are better off freezing the un-shelled acorn and just leaching and grinding as you need it. Frozen, vacuum-packed acorns still in their shell can last up to a year.

White oaks (Quercus alba) produce the least bitter nuts, followed by Red oaks (Quercus rubra) but even both of these need the tannins leached from their acorns. White oak acorns mature in one year while Red oak acorns take two years to complete their growth. Pin oaks (Quercus palustris) are related to Red oaks while Bur oaks (Quercus macrocarpa) are related to White oaks. Live Oaks (Quercus fusiformis) produce the least desirable acorns as they are hard to remove from their shells and are very bitter.

To use acorns as a caffeine-free coffee substitute coarse-grind them then roast them at 400F in an oven to a dark brown color. At this point you can use them just like ground coffee.

The oak gall wasp likes to lay its eggs under the tender bark of new oak twigs. Doing so somehow triggers the formation of a round oak gall. The oak tree doesn't like this much and starts pumping assorted chemicals into the gall to try and kill the wasp larva. The end result is a small, hard ball loaded with medicinal properties. These galls were crushed and then used to make ointments, tinctures, medicated oils, and teas to fight infections inside and outside of the body. The crushed oak galls were also combined with iron salts in vinegar to create a very dark, non-fading ink.

The evergreen agarita is a common 2’-6’ shrub found across Texas, New Mexico, and Arizona. Its unusual, three-part leaves are grey-green, very stiff and pointy so harvesting their fruit can be a bit painful. The yellow flowers appear in late winter followed by red, edible fruit in the spring. Agaritas prefer dry areas with well-drained and somewhat alkaline soil along with full sun to partial shade. The shrubs usually gather around mesquite and other small trees. I haven't seen any out standing alone.

In Spring agarita shrubs are loaded with small, bright red berries. These sweet, slightly tart berries can be eaten raw or cooked in any manner one would prepare any berry such as jam, jelly, or wine. The juice from these berries has a pleasingly complex sweet and sour flavor. The small seeds can be roasted then ground for a caffeine-free coffee substitute.

Agaritas have multiple medicinal uses. The leaves can be chewed fresh or dried to help relieve nausea, especial that accompanying hangovers and motion sickness. A tea made from dried leaves will also offer relief. The yellow wood of the roots contain anti-bacterial and anti-viral compound berberine along with bitter components to help with digestion and other stomach issues such as diarrhea. The root wood is usually finely shaved and then made into a tincture with vodka.

Berberine may inhibit the shortening of chromosomal telomeres during cellular replication, which in turn prevents the physical aspects of aging. For this reason, I've started including it in my Immortality Elixir

Dangers: nut husks are very prickly

Leaf Arrangement: The Chinkapin tree typically exhibits alternate leaf arrangement along the branches.

Leaf Shape: Leaves are generally long, narrow, and sharply toothed, with lengths ranging from 3 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 multiple-trunked. Exact measurements can vary, but diameters may range from 0.5 to 2 inches.

Flower Spike: In the spring, the tree produces long clusters of small, tan-yellow flowers, adding visual appeal. Flowers can be around 0.2 to 0.4 inches in size.

Flower Structure: Individual flowers are small and lack showy petals. Colors can include tan-yellow.

Seed Head: The Chinkapin tree forms sharp, spikey pods containing small acorn-like nuts in the fall. The length of the seed head can range from 2 to 4 inches.

Seed Characteristics: Nuts are small, round, and lack tannins, providing a sweet, nutty flavor. Diameter may range from 0.5 to 1 inch. Colors can include brown.

To stumble upon a stand of Allegheny Chinkapins is to stumble upon treasure. These large, usually multi-trunked bushes/small trees suffered from Chestnut Blight leading to reduced numbers across much of North America. A rare stand can still be found growing under larger trees in the sandy soil of tall banks overlooking water. The sandy soil gives them the drainage they need to avoid root-rot while the larger trees partially protects them from the fierce Texas sun. The long, narrow, sharply-toothed leaves, deep green on top and pale underneath, are arranged in an alternate pattern along the branches. In the spring long clusters of small, tan-yellow flowers hang from the tree. By fall these clusters have been replaced with sharp, spikey pods, each containing what looks like a small acorn.

Harvesting these nuts takes some work as they cling to the tree and are protected by the sharp, spiny remains of their outer husks. One usually has to carefully pick nuts off the shrub/tree one by one. You are likely to find some of the nuts have already germinated while still attached to the tree. Don't eat these but instead carefully plant them nearby.

Allegheny Chinkapin nuts lack tannins or other bitter compounds and so have a sweet, nutty flavor when eaten raw. Being so rare, limit yourself to just a nut or three. Take a few more to plant in similar locations so as to try and bring back this amazingly delicious treat. Animals love these nuts so getting them before squirrels, raccoons, possums and the such is tricky.

Like chestnuts, Allegheny Chinkapin nuts can be roasted to give almost a chocolatey sort of flavor. Place the uncracked nuts on a cookie sheet in an oven at 350F. After five minutes pull out a nut, crack it open and taste it. The roasting time is a personal preference but if the nuts' shells begin cracking it's definitely time to pull them out.

If you do over-roast the nuts they can still be used to make a caffeine-free coffee substitute. Grind the shelled nuts in a coffee grinder then either use them as is or combine them with real coffee to make a pot of brown, somewhat bitter fluid.

People are surprised to learn sweet alyssum is actually a mustard (Brassica family). It's "fairy spiral" arrangement of seed pods and the four-petaled, six-stamened (4 tall, 2 short) flower are the clue. Generally considered to be a cool-weather plant, sweet alyssum is found in many flowerbeds fall to spring. Come summer’s heat they wilt and are usually removed.

While the flowers have a wonderful sweet aroma, the name "Sweet Alyssum" is somewhat misleading when it comes to flavor of raw, young, green seed pods which have the same spicy bite of other mustards. This makes them a funky replacement for radishes in a salad. They also go well with meats where one would normally add a dash of horseradish. The flowers can be eaten any time but the seed pods have the best texture/mouth-feel when still soft and green. The flavor of the leaves is unpleasant to most people but can still be cooked in the same manner as traditional mustard greens.

Warning: Beware of pesticides when harvesting sweet alyssum from flower beds, though if you are following the law you will have already talked to the owner and he/she can tell you if the bed had been sprayed.

North American distribution, attributed to U. S. Department of Agriculture.


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.

Barbados cherries originally come from the Caribbean. When it was discovered a single berry contains the daily recommended dose of vitamin C it was quickly adopted by navies to help against scurvy and so planted in many places. The plant doesn't handle cold well, though it does fine in normal Southern winters if only a few hard frosts occur. They are evergreen, which increases their appeal in landscapes.

The flowers can be eaten raw or used to make tea. However, it is best to leave the flowers alone so as to maximize fruit production.
The fruit starts appearing in May and will continue to appear waves through the winter if the weather is mild. These berries range in flavor from somewhat sweet to very acidic, with the higher acid content also having the higher vitamin C. Eat the berries raw if they aren't too sour/acidic, otherwise use them in jelly, jam, juice or wine.

Many plant nurseries have Barbados cherries for sale. Plant in sunny, well-drained soil but do keep them watered. A layer of mulch will help prevent the roots from drying out. Single plants will produce berries but the fruit production will be much higher if two or more Barbados cherries of different varieties are planted within 4-16 feet of each other for cross-pollination.
