Lantana

Asergio - perfect ID. Pretty plant. They will get black seeds that birds love to drop all over your yard.

Thank you, HeatherMiller. I found another name for this species in the Internet, and it seems more suited to this case:

Hummingbirds, butterflies and bees LOVE my lantana. This is a pretty color and I'm sure attracts different set of critters because of the different color.
