For gardeners wanting a mass of warm summer colors, consider planting 'Landmark Citrus' Lantana. This variety mounds nicely up to 20 inches tall, and up to two feet wide, often covered with clusters of yellow and orange flowers. Somewhat drought tolerant in the ground, lantana prefers to be on the dry side rather than too wet, and loves the sun. 'Landmark Citrus' lantana works well as the centerpiece in container planters, adding color and texture all summer long.
