Description

This low and spreading shrub is one of the most popular low maintenance flowering shrubs planted throughout the Inland Empire. It has a dense mat-like habit with tightly knitted stems, growing 12-18 in. high and 5-10 ft. across. Foliage is comprised of dark green leaves, 1-2 in. long that are high pungent when cut; showy flower heads of purple and white occur from summer through fall and intermittently year round.

Native to South America, trailing lantana has proven to be widely adapted to many types of soil, exposure and moisture conditions in California and the Inland Empire. It is commonly planted in residential gardens and commercial landscapes as a slope and erosion control plant. Once established, it grows very well with reduced summer moisture and has proven to be a reliable landscape choice. One cultivar, L. m. 'Alba' is a white flowering selection that is often mixed with the purple flowering species to achieve a pleasing blend of white and purple flower character.

Water Needs

The trailing lantana thrives in Inland Empire gardens with normal winter rains and monthly summer irrigation. The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. It should be noted there are several months indicated by an asterisk (*) when winter rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water; a monthly summer irrigation schedule is sufficient to achieve good flowering character from June to October.

Maintenance

Lantanas naturally want to become very wide plants. For lantana to remain a low maintenance plant, they must be planted where they have space to become their full size or must be planned as a hedge by design (S). Prune to cut back lightly as a hedge almost any time of the year. Foliage and branches may be damaged by frost, but plants will almost always rebound once the weather warms up in spring. If possible, and depending on appearance, it is better to wait to remove frost damaged branches and foliage until all risk of additional frost has passed for the season because the damaged material protects the rest of the plant from further frost damage. Plants can be cut back as hard as desired, including almost all the way to the ground, in early spring, and most often rebound vigorously (S).
