NC State Extension Publications


All plants in this table can be found in North Carolina; those that are native to North Carolina can be used in landscaping. Some of the non-native species, such as white clover, are widely established in lawns and gardens where they do little harm and may provide useful resources. Invasive and problematic plant species are highlighted red with bolded text; we do not recommend adding or encouraging these species in a home landscape.

* Plants that are only reported to genus often include a mix of native and non-native species. Before acquiring plants from these genera, confirm that the species you have in mind is not invasive; major invasive groups or species are highlighted in red text. Where species are native to only part of the state, they are indicated with M (mountains), P (piedmont), or C (coastal plain).
