One reason native plants stand up to extreme temperatures – Evolution
Native plants have developed drought resistance because they evolved by surviving extreme environmental conditions. Drought, wind, and fire along with the grazing of large herbivores have made them resilient. A major part of this toughness is due to their roots. Native plants tend to have deep roots and or fibrous roots that allow them to survive. One of those hardy natives is Purple prairie clover (Dalea purpurea) that has a woody taproot that extends 5.5 to 6.5 feet. Some native plants have roots that can reach 10-15 feet.
