Wild Weeds – Weed of the Month
Lantana is a tricky plant in natural areas. There is a Florida native lantana, L. depressa, but unfortunately it is now considered endangered. Majority of lantana found in natural landscapes in Florida is the invasive species, L. camara. This perrenial plant is often used in ornamental landscapes because of its unique clustered flowers with varying colors. The native lantana is only present with yellow flowers whereas L. camara can appear with red/orange, light/dark pink, and other color variations.
Each species of Lantana is highly prolific and can reproduce vegetatively or by seed. Each plant can produce in upwards of 12,000 seeds! These seeds are spread by animals across the state increasing the ability of the species to become invasive. It is important to note that Lantana is toxic to livestock.
Glyphosate is marginally effective as a foliar spray and regrowth is common. Fluroxypyr (Vista) plus aminopyralid (Milestone VM) at rates of 2.6 pt and 7 oz/A, respectively, applied twice within 6 months is effective, but costly. Fluroxypyr or imazapyr applied as a basal application is consistently effective. However, mowing and spraying the freshly cut stumps is the easiest application technique and requires the least amount of herbicide.
