Invasive plants are plants that are not from a place and take over habitat to such an extent that they cause harm to the abiity of plants which are from the area to grow and exist. Control of these plants is important because native plants support native insects and native animals. The destruction of habitat through the growth of invasive plants has significantly contributed to the crash in songbird populations for example. Invasive plants also threaten crops and fisheries and block waterways. There are also some native plants that are weedy. Below is a slide show of all the invasive species as listed by the Rhode Island Invasive Species Council.

These are native plants that grow aggressively or do not have particularly attractive flowers or cause rashes (poison ivy) that make them a little more challenging to have in the garden. That said some of them are fine garden plants if used wisely.
