[0] Mahonia/Berberis trifoliolata AGARITA [2] Large PRICKLY perennial shrub found in full sun to part shade. I have found it all over Central Texas, seeming to prefer rocky Hill Country and Blackland gumbo. Likes to grow under larger trees, like Juniperus. Wild seeded as an understory may have more success. Some species seems susceptible to fungal infections. [3] Aboveground parts harvested in spring. Berries in late spring/early summer. Roots are not necessary for potent extract. Made into powder, tea, tincture, oil [1] 
Antimicrobial bitter, contains berberine , used to treat digestive and other infections. Berries eaten and in jellies, wines. Attracts bees, insects birds and small mammals. Other species useful but one is endemic and best if cultivated, a “no pick”
