Safety Overview
1.Lantana Montevidensis — Essential Profile
Lantana montevidensis, commonly known as trailing lantana or purple lantana, is a charming, low-growing perennial shrub belonging to the Verbenaceae family. Native to South America, specifically Uruguay and Brazil, this species is widely cultivated globally for its ornamental value and resilient nature. It typically forms a dense, sprawling groundcover, reaching heights of 1 to 2 feet (30-60 cm) but spreading outwards significantly, often cascading gracefully over walls, rockeries, or containers.
The plant's slender, often wiry stems are arching, contributing to its characteristic mounding habit. Its foliage consists of opposite or occasionally whorled, simple, ovate to elliptic leaves, measuring approximately 1-2 inches (2.5-5 cm) in length and 0.5-1 inch (1.2-2.5 cm) in width. These dark green leaves have a slightly rough, textured surface and emit a distinctive, somewhat pungent aroma when crushed, a common trait across many Lantana species.
The leaf margins are typically serrated or finely toothed.
The most striking feature of Lantana montevidensis is its exceptionally long and abundant blooming period. Small, tubular flowers are arranged in dense, flattened cymes, usually 1-2 inches (2.5-5 cm) in diameter, appearing at the terminal ends of branches. While vibrant purple or lavender-pink flowers are most common, white and other color variations exist.
Each tiny flower possesses four lobes and often a contrasting yellow or lighter-colored throat, adding to its visual appeal. This profusion of blooms extends from spring through fall, and in warmer, frost-free climates, it can flower continuously year-round, making it a significant attractor for various pollinators, particularly butterflies and bees. Following successful pollination, small, dark purple to black, berry-like drupes develop, though these are generally less noticeable than the flowers and are considered mildly toxic if ingested.
