Ruellia geminiflora, commonly known as ipecacuanha-da-flor-roxa, is a perennial herb native to diverse ecosystems from Mexico to South America. This species thrives in well-drained soils and is adapted to both full sun and partial shade conditions. It typically exhibits a fast growth rate and can reach heights of 2-3 feet with a similar spread. Ruellia geminiflora is characterized by its lance-shaped leaves and tubular, purple flowers that bloom in the warm months, providing a showy display that attracts pollinators such as bees and hummingbirds.

In cultivation, ipecacuanha-da-flor-roxa is valued for its vibrant flowers and ability to adapt to various soil types, although it prefers those that are well-drained. It is often used in borders, as a ground cover, or in naturalized areas where its spreading habit is desired. Regular watering is necessary, especially in dry conditions, but once established, it can tolerate short periods of drought. There are no widely known cultivars of this species in the horticultural trade. Gardeners should be aware that Ruellia geminiflora can become invasive outside its native range due to its vigorous growth and self-seeding habit, so caution is advised when planting it in suitable climates.CC BY-SA 4.0
