Heat and humidity-loving lantana thrives in the well-drained soil of containers and carpets the ground with rich green foliage and an abundance of butterfly-attracting flowers. However, it can be invasive when grown as a groundcover in warm winter areas where it is perennial. Pinch when setting out to encourage branching. Deadhead any developing seed heads throughout summer and fertilize with low nitrogen flower fertilizer midseason for continued full bloom. A good choice for beachfront plantings, as they tolerate salt. Caution: Mild toxic effects may occur if berries are ingested.
