Ask Mr. Smarty Plants

We have a list of Edible Native Texas Plants that lists plants found in our edible plants garden.  Not all of those are native to your area, of course, but you can determine which ones are by opening the species page for each plant and scrolling to the bottom of the page.   When you find the entry for ADDITIONAL RESOURCES there click on the USDA link.   This will take you to the USDA Plants Database page that has a distribution map for that plant.  If you click on Texas on the map, it will show you the distribution by county for the plant and you can determine if it occurs in or adjacent to Real County.  If you click on the county distribution map again, it will give you the names of the counties as well.

Below are some edible native plants that occur in or adjacent to Real County:

Allium canadense (Meadow garlic) and Allium drummondii (Drummond's onion)

Cercis canadensis var. texensis (Texas redbud).  The flowers are delicious in a salad or added to pancake batter or muffins.

Diospyros texana (Texas persimmon). According to Delena Tull in Edible and Useful Plants of Texas and the Southwest:

"When fully ripe, the sweet rich fruit has a flavor that resembles that of a prune.  The astringency of the unripe fruit makes your mouth pucker and leaves a horrid taste, so use only the soft juicy fruit."

Hedeoma drummondii (Drummond's false pennyroyal) smells and tastes like peppermint and can be used as herbal flavoring and teas.

Juglans microcarpa (Little walnut) is delicious but difficult to extract from its hard case.

Malvaviscus arboreus var. drummondii (Turk's cap or turkscap) fruits can be eaten raw or cooked.

Monarda citriodora (Lemon beebalm) makes a strong-flavored tea.

Oenothera speciosa (Pink evening primrose) young leaves are delicious in a salad or cooked as a green.

Oxalis drummondii (Drummond's woodsorrel) can be used as addition to a salad or as a flavoring in soups or vegetable dishes.

Tradescantia gigantea (Giant spiderwort) young tender stems, leaves and flower parts can be used raw in salads or added to soups, stews and sauteed vegetables.

Vitis cinerea var. helleri (Winter grape)

Vitis monticola (Sweet mountain grape)

Prosopis glandulosa (Honey mesquite) meal made from the roasted and ground beans can be used in many recipes.

Celtis laevigata (Sugar hackberry) has edible berries.

Please see the answer to a previous question about edible plants around Austin, TX.  Although not all the plants mentioned in the previous question occur in or adjacent to Real County, the description of the uses of the plants that do are relevant to your question.
