Lantana's aromatic flower clusters (called umbels) are a mix of red, orange, yellow, or blue and white florets. Other colors exist as new varieties are being selected. The flowers typically change color as they mature, resulting in inflorescences that are two- or three-colored.
"Wild lantanas" are plants of the unrelated genus Abronia, usually called "sand-verbenas".
Biological control of introduced lantanas has been attempted, without robust success. In Australia, about 30 insects have been introduced in an attempt to control the spread of lantanas, and this has caused problems of its own. The lantana bug (Aconophora compressa) for example is a polyphagous species introduced in 1995 that feeds on dozens of plants, and not only has it failed to have a noticeable impact on the lantana population, it has even become a pest in horticulture, parasitizing the related fiddlewoods (Citharexylum). The small Lantana-feeding mothsEpinotia lantana and Lantanophaga pusillidactyla, while not becoming pests, have nonetheless failed to stem the spread of the invasive weed, as has the lantana scrub-hairstreak butterfly (Strymon bazochii) which was introduced to control lantanas on the Hawaiian Islands.
Lantanas are useful as honey plants, and Spanish flag (L. camara), L. lilacina and L. trifolia are sometimes planted for this purpose, or in butterfly gardening. Butterflies which are attracted to lantana flowers are most notably Papilioninae (swallowtail and birdwing butterflies). Hesperiidae (skippers) and certain brush-footed butterflies (namely Danainae and Heliconiinae), as well as some Pieridae (e.g. cloudless sulphur, Phoebis sennae), Lycaenidae (e.g. the aforementioned lantana scrub-hairstreak), and Nymphalidae (e.g. Greta oto) also like to visit the plants' flowers. Consequently, as total eradication of Lantana seems often impossible, it may in many cases be better to simply remove plants with immature (green) fruit to prevent them from spreading.
Some weaverbirds such as the black-throated weaver (Ploceus benghalensis) and the streaked weaver (P. manyar) highly value Lantana flowers for decorating their nests. An ability to procure spectacular and innovative decorations appears to be desired by females, and consequently is an indicator of the males' fitness.
In Australia it has been found that removing Lantana from urban greenspaces can have negative impacts on bird diversity locally, as it provides refuge for species like the superb fairy (Malurus cyaneus) and silvereye (Zosterops lateralis) in the absence of native plant equivalents.[5] There seems to be a density threshold in which too much Lantana (thus homogeneity in vegetation cover) can lead to a decrease in bird species richness or abundance.[6]
Most of the plants sold as lantana are either Spanish flag (species of section Lantana and their hybrids, including L. camara, L. depressa, L. hirsuta, L. horrida, L. splendens, L. strigocamara, etc.), or trailing lantana (L. montevidensis).[10] Numerous cultivars of the Spanish flag exist, including 'Irene', 'Christine' and 'Dallas Red' (all tall-growing cultivars) and several recently introduced shorter ones. The shorter cultivars may flower more prolifically than the taller ones. Lantana montevidensis gives blue (or white) flowers all year round. Its foliage is dark green and has a distinct odor.
Although lantanas are generally hardy and, being somewhat toxic, usually rejected by herbivores, they may still become infested with pests.
The edibility of Lantana berries is contested. Some experts claim Lantanaberries are edible when ripe[11][12][13] though like many other kinds of fruit, they are mildly poisonous if eaten while still green. Other experts claim that experimental research indicates that both unripe and ripe Lantana berries are potentially lethal, despite the claims by others that ripe berries are not poisonous.[14]
Tribal people of the MM Hills in southern Karnataka, India, produce roughly 50 different types of furniture from lantana. It is considered a "near match" to the more highly-priced cane and bamboo, while being resistant to sun, rain, and termite damage.[16]
