Stuck on Perennial Peanut’s Beauty
By Cynthia Hight
“Peanut is amazing. My horses love it and it’s highly nutritive for them.” I was talking with a student working alongside me in the Agronomy Department at the University of Florida. She explained that the annual rhizome variety, arachis glabrata, does not produce on its roots the peanuts we eat. It was often planted with pasture grass to benefit grazing animals. She lit up as she added, “It adds nitrogen to the soil, thrives in poor soil conditions, and is drought resistant.”
I was hooked.
Around the campus, perennial peanut was planted in multiple places of low foot traffic to replace turf grass. The tiny, orchid-like yellow flowers bloomed nearly year-round. When mowed, the flexible flower stem pops back up, creating a gorgeous carpet of yellow.
After moving to East Texas, and becoming a Certified Master Gardener, my quest was to establish perennial peanut. But I was warned by my Texas A&M instructors that our zone is too cold for perennial peanut, and they redirected me to alternative ground covers.
I wanted to prove them wrong.
In one yard section, I planted 24 one-gallon plants in late Spring 2023, 18 inches apart to allow spread. In the bare areas, I cast clover seed to help choke out weeds and add nitrogen to the soil. The area is in part shade and the house acts as a block against winter wind.
I figured that since peanut grows in poor soil, thus great for erosion control, that I could skip a few steps shared during Master Gardener training. I did not first kill the weeds and ignored the soil test.
Half of the plants became established. The shade inhibited the spread, and weeds were everywhere. I transplanted the plants in full shade to full sun, and discovered tap roots longer than two feet. Impressive! The peanut and clover attracted foraging deer, which eliminated the need to mow.
A second area was planted with 40 plugs on July 1, 2024 in full sun. You are correct to exclaim, “Bad timing!” To explain, I was trying to improve the yard’s appearance before party guests arrived. Vanity was fleeting, and the plants struggled that summer.
I blame my alter ego, which I refer to as Ben Stuck, for all the failures. “Just experiment,” Stuck goaded. “Try the Shortcuts.”
Frost came and everything died back. Stuck heckled, “Dead or dormant?” Less than half the plants reemerged in Spring.
Seeking to blame someone other than me, I pointed to my grandfather. He affectionately called me “Gober,” and thus began my fondness for peanut. When I worked in the Agronomy Department and learned peanuts, mostly the consumable legume, offered food security on a global stage, it gave me a sense of purpose.
The yellow flowers bring terrestrial sunshine. But maintaining perennial peanut is higher maintenance with a short growing season. When will I learn to follow the science? I’m too stuck on its beauty.

Perennial peanut, arachis glabrata, can be established in East Texas as a landscaping ornamental ground cover. The flowers are edible, for those without peanut allergies, and provide a beautiful garnish. Cooler soil creates long periods of dormancy. Although low maintenance when temperatures are warm temperatures, expect to cover in winter to prevent dying.
