Our friend and former Oklahoma Gardening show host, Ray Campbell shared this reliably perennial Lantana with us after growing it for number of years in his Stillwater garden. Carnival Lantana lives up to its name. Its flowers are definitely not subtle, with their festive mixture of yellow, pink and lavender. You see the different colors as each individual flower changes as it ages. Since new buds continue to open in the center of the cluster, you always have this lively mix. As with all perennial Lantanas, cut it back hard before growth begins in spring to keep it tidy and compact.
