Three-leaved lantana comes from the tropical regions of South and Central America and Mexico, growing 2 to 5 feet tall as a loose, upright shrub with foliage arranged in characteristic whorls of three. In North Carolina and similar climates it functions as an annual or can be carried through winter indoors, with cuttings taken in fall to start fresh plants for the following season. The lavender flowers appear through the growing season and are attractive to bees and other pollinators, but the plant's most distinctive contribution comes after the flowers: elongated, popcorn-like fruiting spikes in soft lavender-purple that persist and develop through fall.

This ornamental fruit is the reason many gardeners seek it out. In borders or tropical-themed plantings, the fruiting spikes add a textural element unlike most common annuals, extending visual interest well beyond the bloom period. Average, well-drained soil suits it well and it tolerates poor conditions, asking mainly for warmth and sun to perform at its best. Deer resistance and the usual lantana toughness make it a low-maintenance choice for summer through fall interest in gardens where the unusual is welcome.
