I originally had this lantana shrub in the plastic pot it was in when I bought it at the garden shop. Over last winter, I thought it died, but I planted it in a partial sun spot in the back flowerbed. To my surprise, it came back in the springtime and is almost two feet tall and wide today.
According to Floridata, lantana is a native to tropical regions and exists as dozens of strains and varieties. A lantana may look orange from a distance but when the flower head is examined at close range it consists of individual yellow and red flowers that blend when viewed from afar. You can see that detail in this photograph.
