I’ll be showing you how I prune my Lantana “Dallas Red” which grows to around 4’x 5′ and my Lantana “New Gold” which is a ground cover at 1-1/2′ x 4′. Both are prolific bloomers which attract a multitude of hummingbirds and butterflies.
Lantana’s long flowering season is most likely the reason it’s widely seen growing as a perennial in California, Arizona, Texas, Louisiana, Mississippi, and Florida.
Lantana is hardy in USDA zones 8-11. It grows very fast once the weather warms up and can handle the summer heat here in Tucson just fine. Although it’s a perennial in many areas, you can most likely find it sold as an annual in winter cold climates.
I was visiting my friend in Connecticut one summer and she had it growing as an annual in a pot on her back deck. The hummingbirds were very happy!
