Incorporating Native Plants in Your Garden – What Defines a Native Plant? By EMG Jenn
Every Tuesday, we talk a lot about desirable native plants. But what makes a plant native or invasive, or a non-native which is not considered invasive?
Native plants are those that occur in the region in which they evolved and have adapted to the local climate and soil conditions. Native insects and wildlife have evolved along with the plants, and many can feed only on the plants with which they co-evolved.
Invasive plants are species intentionally or accidentally introduced by human activity into a region in which they did not evolve, and cause harm to natural resources, economic activity, or humans.
Some friendly garden plants are neither native nor invasive.
For example, Virginia Bluebells (Mertensia virginica) are native to Virginia. Japanese Honeysuckle (Lonicera japonica, pictured) is not native and is considered invasive. Many of the plants we grow in our gardens to produce food are neither native nor invasive. Basil, for example, is native to tropical regions of Central Africa to southeastern Asia.
Ideally, we want to aim to have about 70% native plants in our gardens, meaning that if a non-native is not considered invasive, you don’t have to feel any guilt about having it in your garden. But shoot for that 70% benchmark!
