110 Appendix A —Nonnative Invasive Plant Species Not to be Used or Recommended for Ornamental, Landscapes, Food/Herbal Plantings, or Water Gardens Most of the southern plant invasions have started from escaped ornamental plantings that have occurred over 400 years and continue today. The increasing deluge of aquatic invasive plants destroying native communities that inhabit our natural waters and wetlands are coming from those used and discarded from home water gardens. Homeowners are free to plant and “over the fence” discard a full range of commercially available plants without regard to their inva- siveness unless restricted by local, State, and Federal regulations (mainly focused on agricultural pest introductions) or community covenants. Some, like English ivy, silverthorn, Bradford pear, and silver plumegrass are even required by some subdivision covenants. Many of these escaped ornamentals are now widely recognized and listed as invasive species, but consumers are unaware or complacent of the real dangers they pose to natural communities as they replace our native plants. Invasive plant species are still frequently recommended in State horticultural extension bulletins and manuals. The threat is worsened as both traditional and new invasive plant species are mass produced by the plant industry and sold through large and small outlets that are essentially insulated from the current knowledge of the incurred societal costs. Landscape architects have been trained to select invasive plants for creating ornamental and horticultural landscapes with repeated composition and plant forms with little or no understanding of the greater consequences. Other invasive plants can be bought through the Internet, especially those used in oriental cooking and herbal mix- tures. The most aware and bothered public are those that must persistently fight back invasive plants taking over their properties and parks plagued by unwise planting choices by neighbors, communities, cities, and highway departments. This is a “do not plant” list of invasive ornamental (and some oriental food and herbal) plants recognized and listed by State and Federal Agencies and exotic pest plant councils. As a good neighbor and land steward, please do not plant these plants and remove any that already exist from your property. Even a small number of plants can cause eventual destruction to the healthy surrounding plant communities and their environment. Wind, water, birds, and mammals are perpetually transporting ornamental invasive plant parts, fruit, and seed throughout the urban, suburban, and rural landscapes. These escaped plants move outward to invade surrounding lands and waterways. With your individual invasive plant management efforts and conscientious use of noninvasive plants in your landscape, we can assure a better future for coming generations. Please ask ornamental plant growers and outlets not to grow or sell these plants. It is recognized that seed viability can vary by cultivar and populations, while hybridization can result in increased viability.
