Interpretive Summary: Lantana ornamental plants are valued by bright-colored flowers and other desired attributes including attraction to multiple species of butterflies, tolerance to drought, heat and salt, low maintenance requirement, and easy propagation. In Florida, Lantana camara is listed as a Category I invasive species and not recommended for production and landscape use because escaped L. camara plants can endanger native L. depressa through interspecific cross. To avoid the risk, a new infertile cultivar of L. camara, ‘UF-1013-1’, is released to meet the need of the industry. This cultivar possesses stable male and female infertility, typically does not produce viable seeds, does not set fruit reciprocally with L. depressa, and thus has little potential to produce viable interspecific offspring. Compared to ‘Bloomify Red’ (a sibling of ‘UF-1013-1’), ‘UF-1013-1’ shares the similar high male and female infertility and superior plant performance rating, but differs in plant and leaf morphology, nuclear DNA content, and molecular marker profile.Lantana ornamental plants are valued by bright-colored flowers and other desired attributes including attraction to multiple species of butterflies, tolerance to drought, heat and salt, low maintenance requirement, and easy propagation.

Technical Abstract: Lantana L. is a genus in the Verbenaceae family containing species for ornamental plants that are valued by bright-colored flowers and other desired attributes, including attraction to multiple species of butterflies, tolerance to drought, heat and salt, low maintenance requirement, and easy propagation. However, in Florida, L. camara is listed as a Category I invasive species by the Florida Exotic Pest Plant Council and is not recommended for production and landscape use because escaped L. camara plants can endanger native L. depressa through chance hybridization. To circumvent the risk, a new infertile cultivar of L. camara, ‘UF-1013-1’, is released to meet the need of the industry. This cultivar possesses stable male and female infertility, typically does not produce viable seeds, does not set fruit reciprocally with L. depressa, and thus has little potential to produce viable interspecific progeny. Compared to ‘Pink Caprice’, a cultivar of L. camara that is closest to the species resident taxon (wild or naturalized type), the pollen stainability of ‘UF-1013-1’ has been reduced by at least 95%. Fruit production of this triploid cultivar has been reduced by greater than 99%. ‘UF-1013-1’ is a sibling of ‘Bloomify Red’ (previously released as ‘UF-1013A-2A’). Compared to ‘Bloomify Red’, ‘UF-1013-1’ shares the similar high male and female infertility and superior plant performance rating, but differs in plant and leaf morphology, nuclear DNA content, and molecular marker profile.
