Native to Mexico, this plant has become a beloved favorite worldwide due to its low-maintenance nature and stunning aesthetic appeal. This article delves into the various aspects of Russelia equisetiformis, from its botanical characteristics and cultivation to its ecological significance and landscape applications.

Botanical Characteristics and Taxonomy

Stems: Long, thin, and arching, creating a fountain-like effect. These stems are typically green and wiry.

Leaves: Small, scale-like, and often inconspicuous, as the plant primarily relies on its stems for photosynthesis.

Flowers: Abundant, tubular, and bright red, though pink, orange, and white varieties exist. The flowers are typically about 1-2 inches long and are produced in profusion, creating a dazzling display.

Growth Habit: A semi-woody shrub that can reach heights of 3-5 feet and spread equally wide.
