The following represents a list of non-native (alien or exotic) plant species that are established in the state of Delaware. A species which occurred in Delaware prior to European settlement, or which has migrated into the state independent of human activity, is considered "native and indigenous." Native indigenous species in Delaware have evolved in specific habitat types and have become, over time, genetically adapted to the local environmental conditions of the area.
A plant species not native to North America is thought to have been introduced by humans, primarily through agricultural or horticultural practices. These species have become established in Delaware and are reproducing as if native (i.e., naturalized). Many alien plant species (e.g., Lythrum salicaria, purple loosestrife; Microstegium vimineum, Japanese stilt grass) are often very aggressive and out-compete and displace native vegetation; others (e.g., Daucus carota, Queen Anne’s lace) are less invasive and are thought to pose no, or little threat to native flora and ecosystems.
A species native to North America, but not to Delaware, which is now found growing in Delaware outside of its natural range is considered to be adventive. Adventive species are not part of Delaware’s native flora. These species usually arrive due to the human-caused breakdown of natural barriers to dispersal. In most cases, adventive species usually have not yet become widely or well established and may or may not be a threat to indigenous plant communities in the state. Adventive species also include native plants that have been introduced, or intentionally planted in Delaware and are now escaping and surviving without cultivation; such species usually do not become widespread. There are 70 adventive plant species listed, indicated by: ü .
Phragmites australis (common reed) is a grass native to North America and Delaware, but is included on this list due to its aggressive, invasive nature. Phragmites australis is well established in wetlands throughout the state and often forms pure stands that will displace other native vegetation. It is thought that the aggressive monotypic populations that we see today in Delaware are a result of hybridization between North American and European genotypes.
Taxa found on this list are based on the literature, collections, field observations and knowledgeable individuals (sources are available on request). To date, there are 610 species and varieties of non-native vascular plants known to occur in Delaware, which represents 28% of the state’s known flora (there are 1565 native vascular plants known to occur in Delaware). Taxa found on this list are arranged alphabetically by scientific name. For the convenience of the user, a supplemental list (Appendix I) is also provided that is arranged alphabetically by common name. Please be aware that common names are not standardized and a particular plant may have more than one common name. Nomenclature for scientific and common names follows: McAvoy and Bennett, The Flora of Delaware, an Annotated Checklist, published by the Delaware Natural Heritage Program, 2001. Growth form (herb, grass, sedge, fern, vine, shrub, tree, deciduous, evergreen, annual, perennial, biennial) for each species listed is also provided. Species highlighted in bold (64 species) are, or have the potential to be invasive in Delaware. This list does not include horticultural varieties maintained only through cultivation.
