I am a terrible gardener. I try with my perennial garden beds, but the ecologist in me always wants to leave the plants to their own. Let them fend for themselves. Survival of the fittest is the theme. Needless to say, it’s the native plants that don’t need much water and the weedy species that persist. Anyone who has read my previous columns knows that I am not a fan of non-native invasive plants. However, the term “weedy” can be used for a number of plants that may be 1) native, but with fast growing, invasive tendencies (think poison ivy) or 2) non-native species that grow well in ruderal habitats such as roadsides, parking lots, and bike paths.
