Many commonly used garden plants imported to North America have escaped into once pristine natural areas. After becoming a monoculture these species drive out the native species, thereby degrading the ecosystem and lowering species diversity. Alex Dencker will discuss some problematic plants, highlight the damage they’ve done and continue to do to our natural areas, and offer native plant alternatives to replace the invasives you may be surprised to learn you have in your garden.
