The Universiy of Illinios Extension Service defines aggressive plants as those that have the ability to "spread fast enough within the garden as to cause issues to other garden areas where the plant is not wanted or is intended to be growing." This is not the same as being identified as being invasive. It's also important to note that there is a difference between a plant being considered invasive and one that grows aggressively. So, although some of the plants above are noted as being invasive in certain regions, they are fine to grow in others. Keep in mind that a plant may be invasive in one environment, but okay to grow in another. From the USDA website: "An invasive species is non-native to the ecosystem under consideration, and whose introduction causes or is likely to cause economic or environmental harm or harm to human health." When learning about plants, it's important to understand what it means for a plant to be invasive.
