The good news about leatherleaf mahonia, no matter where you’re reading this, is that this plant is well adapted to almost any part of Texas. As long as it has shade from the afternoon sun in the summer, this plant just wants a chance to perform.
It’s a cousin to nandinas, barberries, and native beauty of Southwest Texas, the prickly agarita. Like many of its relatives, it showcases its dramatic stems. Its bold leaves are borne off rarely branching stalks that grow to be 4 to 6 ft. tall.
And, yes, the flower clusters are very showy when they’re produced in mid- to late winter each year. They’re a treat for the honeybees, since nothing else is blooming this early.
And the bees do their jobs, because the flowers are soon followed by showy clusters of blue-green fruit that ripen in spring. Many years the fruit are ready by the time ravenous cedar waxwings migrate through town, and then, two hours later, no more fruit on the mahonias.
From that point on through the rest of the growing season they’re standing like proud sentinels toward the backs of my shade beds, behind the dwarf hollies, alongside the Oakleaf hydrangeas and in front of several Japanese maples. Just as they’ve been for 40 years or longer.

Note: North Carolina State University lists this plant as being invasive in the Southeastern United States. Technically I’m sure that is true since birds do favor its fruit, however, I can count on one hand the number of seedlings that have shown up in my gardens in the 40-plus years that I’ve been growing it. I’d rather have it in my landscape than two of our native plants: hackberries or cottonwoods.
