Summary

Ruellia affinis, commonly known as Red Ruellia, is a perennial herb native to Brazil. It typically grows to a height of 2-3 feet (0.6-0.9 meters) and spreads to a similar width. Ruellia affinis has lance-shaped leaves and produces showy, trumpet-shaped red flowers throughout the warm months, which attract pollinators such as butterflies and hummingbirds.

Red Ruellia is appreciated for its vibrant flowers and is often used in borders, as ground cover, or in container gardens. It thrives in full sun to part shade and prefers well-drained soils, though it is adaptable to various soil types. This plant is drought-tolerant once established, making it a low-maintenance option for gardeners. However, it can spread aggressively by self-seeding, which is a potential problem in cultivation.CC BY-SA 4.0
