Yes, it is definitely lantana. While they are perennials in Florida, Kate, I've often seen them used in planters and hanging baskets up north so you could at least enjoy the flowers from now through your first frost.
Fox Hollow Cottage, thank you for that website. They sure are BEAUTIFUL little flowers. I just love LANTANAS. I have the yellow one for about 10 years now.
This is multi-colored Lantana...A native, here in Texas. Grows wild in the ranch country. There is also a yellow variety that is very drought resistant and is lovely in beds.
Are there different varieites? My Lantana has single blossoms, not clusters like this plant
