Flowers have maintained a partnership with insect pollinators from the beginning. They are masters at attracting these love messengers and perpetuating the species through pollination. They use countless ways to accomplish this goal.
Definitions of native plants abound.
None is entirely satisfactory in all circumstances but each may serve a
specific function. Some strive for scientific accuracy; others serve
practical purposes. Moreover, in some instances the nativity of a plant
may not matter to the native-plant gardener. None of us is about to give
up growing tomatoes regardless of their non-native status.
Some important concepts lack a perfect definition. We need to name them, nonetheless. Biologists would be lost if they couldn’t use the concept of “species” just because no definition fits all the circumstances. This word is not only important but absolutely necessary. One may need to use different definitions of “species” depending on the discipline; but that is no reason to give up the word. The concept of “native” organisms is equally necessary. It is here to stay, regardless of the difficulties that may arise at times.
