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.

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.

AlligatorWeed

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.

Alyssum

Scientific Name(s): Lobularia maritima
Abundance: common
What: seeds, flowers
How: raw
Where: flower beds, landscaping
When: Fall, Winter, Spring
Nutritional Value: Vitamins, minerals, phyto-compounds,
Dangers: beware of pesticides

Alyssum

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.

Arrowhead/Wapato

Scientific Name(s): Maranta spp. and Sagittaria spp.
Abundance: uncommon
What: tubers, young leaves, young flower stalks
How: boiled, roasted
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.

Arrowhead

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.

Basswood

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.
