Planting straight native species grown from seed, rather than “nativars,” optimizes genetic diversity. Native plants have the genetic diversity needed to adapt to changes in climate, including extreme fluctuations in temperature, wind, rain, and snow. Nativars are selected for specific characteristics and may not have the same ability to adapt.
