If you are thinking of replacing your lawn with drought-tolerant plantings, consider Lantana. Lantana is a popular drought-tolerant plant that can thrive with little moisture and in full sun. Lantana produces an abundance of brightly colored flowers all summer and fall, and is a magnet for butterflies and hummingbirds. While hard frosts can cause problems for Lantana, plants from local nurseries seem to do OK here once established.
