Fagaceae (Beech Family)

Synonyms: Quercus acuminata, Quercus alexanderi, Quercus prinoides, Quercus prinoides var. acuminata

USDA Symbol: QUMU

USDA Native Status: Native to U.S.

A tree with light gray platy or scaly bark and smooth, gray twigs changing to brown on the current year’s leaf-bearing growth. Leaves up to 8 inches long and 4 1/2 inches wide with their widest part nearer the apex than the base. Larger leaves broadly rounded from the widest part to the apex and tapered to the base, the smaller ones narrower, leaf margins shallowly lobed or coarsely toothed, each lobe or tooth with a minute tip; the upper surface smooth, with a sheen, the lower surface dull. Flowers inconspicuous in narrow clusters. Fruit an acorn up to 1 inch long and 3/4 inch wide.

The common name refers to the resemblance of the foliage to chinkapins (Castanea), while the Latin species name honors Henry Ernst Muehlenberg (1753-1815), a Pennsylvania botanist.

Benefit

Use Wildlife: Hummingbirds
Use Food: EDIBLE PARTS: Acorns (nuts) are edible after tannins are leached or boiled out. Gather nuts during the fall from September to October. Only gather the ripe tan-to-brown acorns, rather than the unripe green ones. remove bitterness, shell the brown, ripe acorns and remove any corky skin layers, dice the meat, and boil the chunks in water from 15 to 30 minutes until the water turns brown. Then pour off the water and repeat the process until the water clears, indicating that the tannic acid has been removed. During the last boiling, salt water can be added; then the acorns can be deep fried or mixed in a soup. Finely chopped acorn meats can be added to bread doughs and muffin batters. After the leaching process, acorn meat can be frozen. To make flour, the boiled acorn meat can be split in two and dried by slowly baking in a 200 degree oven with the door cracked to allow moisture to escape. Crush or grind and use as a thickener or a flour. Another method is to roast the fresh acorn to work well in a grinder or blender. After grinding, place the flour into a cloth bag and boil to leach out bitterness. Leached acorns, after they are roasted until brittle, can be ground and used as a marginal coffee substitute.

Use Other: Liquid merchandise was commonly rolled onto the boat in barrels made of this oak, for though its pores look large, they are admirably plugged by nature and so proof against leakage. (Peattie)
Warning: POISONOUS PARTS: Acorns (seeds of nuts) and young leaves. Low toxicity if eaten. Symptoms include stomach pain, constipation and later bloody diarrhea, excessive thirst and urination.
Attracts: Birds , Hummingbirds , Butterflies

Mr. Smarty Plants says

Question: We recently added a deck in our backyard which faces west, we live in Circle C (southwest Austin). The afternoon sun is intense so we're looking to plant something along our fence line to provide shade and privacy. We want something quick growing that will grow tall (20 or so feet) but not wide, since we don't want it to take up valuable yard space, maybe a tree? Also, can you recommend a flowering vine that can grow from the ground and climb to cover our brick patio columns. I'd love something fragrant, but nothing poisonous or that would attract bees.

Question: We live in Kempner Texas, our land has mostly cedar trees. We would like to make a wildlife habitat on the back side of our property. Can you recommend plants that will grow in shade to partial sun, compatible with cedar and wildlife friendly? Also we want a good shade tree for our front.
