Alternatives to Invasive Plants Commonly Found in Central Florida Landscapes1

Gary W. Knox, Sandra B. Wilson, Zhanao Deng, and Rosanna Freyre2

Invasive plants are non-native plants that form expanding populations in natural areas and other plant communities with which they were not previously associated (Langeland 2012). Invasive plants can cause ecological impacts, such as displacing native plants and associated wildlife or altering natural water flow and fire patterns.

Some ornamentals listed as invasive by the University of Florida IFAS Assessment of Non-Native Plants in Florida's Natural Areas or by the Florida Exotic Pest Plant Council are still in commercial production and widely found in Florida landscapes. Homeowners might replace invasive plants if non-invasive alternatives are researched, publicized, and made readily available. By shifting production and use from invasive ornamentals to native or non-invasive cultivars, the nursery and landscape industry could benefit from potential revenue while fostering greater collaboration with state agencies and environmental groups.

University of Florida research and Extension efforts over the last 10 years have focused on identifying non-invasive alternatives by assessing the invasive traits of popular non-native ornamentals, related genera, and their cultivars. In more recent years, University of Florida breeding efforts have focused on producing and trialing new non-invasive cultivars. Table 1 lists native and non-invasive, non-native ornamentals as alternatives to invasive plants commonly used in Florida landscapes. Only plants considered to be generally available in the nursery trade are listed. Alternative plants are similar to respective invasive plants as much as possible in terms of size, habit, texture, and flower color. Non-native, non-invasive plants in Table 1 were determined to be non-invasive by the IFAS Assessment of Non-Native Plants in Florida’s Natural Areas (IFAS Invasive Plant Working Group 2008) or have not yet been evaluated.

zAs listed by the University of Florida/IFAS Status Assessment. The initial component of the IFAS Assessment of Non-Native Plants in Florida’s Natural Areas (IFAS Invasive Plant Working Group 2008) is the Status Assessment (Fox, Gordon, Dusky, Tyson, and Stocker 2009), in which evidence is reviewed concerning ecological impacts, potential for expansion, difficulty of management, and economic value of non-native species.

yNon-invasive cultivar derived from the invasive species as determined by the University of Florida/IFAS Infraspecific Taxon Protocol (Fox, Gordon, Gantz, Knox, and Wilson 2007). The Status Assessment is generally applied at the species level. It is only applied independently to infraspecific taxa (e.g., cultivars, varieties, or subspecies) if these taxa can be clearly distinguished in the field and are not likely to revert. Other infraspecific taxa (those indicated by this footnote) may be assessed using the Infraspecific Taxon Protocol (Fox, Gordon, Gantz, Knox, and Wilson 2007).
