Our urban tree improvement program supplies hardy trees for future urban landscapes.
The program was established more than 40 years ago to create a supply for trees for future landscapes. The program has produced some of the hardiest, climate-adaptable tree species that are now offered through Texas Tested, Texas Tough.
Texas Tested, Texas Tough
Trees labeled Texas Tested, Texas Tough descend from genetic lines that are proven to withstand a variety of conditions, including drought, heat, and pests. Through selection and testing of local sources of native species, our program is dedicated to enhancing the health, resilience, and beauty of trees in urban environments by increasing viability, vigor, and climate adaptation.
We’ve established seed orchards for eight species:
- Baldcypress
- Bur oak
- Cedar elm
- Chinkapin oak
- Live oak
- Shumard oak
- Southern magnolia
- Sweetgum
Monitored growing
We provide performance information for each of our species and work closely with growers who use our seed to make sure that seedling production standards are met or exceeded. This helps us ensure that only the best selections go into production.
Trees are a life-long investment and growing a Texas Tested, Texas Tough tree ensures a lifetime of enjoyment from a tree tested to withstand the harshest urban environment.
Here is our brochure with information and performance data on the species in our Texas Tested, Texas Tough program and how to get seed.
