A key benefit of growing native plants from seed is it’s the best way to preserve the genetic diversity within a species. In the wild, most plants reproduce by seed. Seeds develop when flowers are pollinated (usually by insects, sometimes by the wind) mixing the genes of multiple individuals. This results in genetically diverse individuals. This variation is a wild plant’s best strategy to adapting to future environmental conditions as individuals differ in their ability to deal with drought, heat, flooding, cold, and pollution.
