​Habitat and Ecology
​Codonanthe gracilis is a species of epiphytic subshrub native to Eastern and Southern Brazil, found primarily within the Atlantic Forest biome. As an epiphyte, it grows on the trunks and branches of trees, often in the specialised environment of "ant gardens." In this mutualistic relationship with arboreal ants, the plant's fibrous roots reinforce the ant nests, and the ants benefit from food rewards like floral and extra-floral nectar, as well as the plant's seeds, which the ants carry into the protective environment of their nests to germinate. This species thrives in the seasonally dry tropical biome, but requires consistently high ambient humidity and filtered light characteristic of the forest canopy.
​Description
​Codonanthe gracilis is a trailing or pendent perennial subshrub, highly valued for its elegant, cascading growth habit. The graceful stems can trail up to 1.8 meters (6 feet) in length. Its leaves are small, pointed, and somewhat fleshy or waxy (succulent), typically presenting a vibrant lime-green colour. The plant is a prolific bloomer, producing numerous small, white, bell-shaped (tubular-campanulate) flowers that often feature a contrasting dark or yellowish throat. Following flowering, the plant develops highly ornamental, showy, spherical berries that ripen to a vivid orange or reddish-orange colour, adding significant decorative interest.
​Cultivation
​This species is a relatively easy-to-grow tropical epiphyte. It requires bright, indirect light and must be protected from intense direct sun. The substrate should be very well-draining and porous, ideally an epiphytic mix such as orchid bark, perlite, and a small amount of synthetic peat. The medium must be kept consistently moist, though you should allow the top layer to dry slightly between waterings; avoid prolonged drought and, crucially, standing water. High humidity (over 50%, ideally 70-80%) is preferred for optimal health and blooming. Optimal daytime temperatures range from 21-25°C (70-77°F), and while it prefers a warm environment, it should not experience nighttime temperatures below 10°C (50°F). Fertilise sparingly with a highly diluted, balanced liquid fertiliser during the active growing seasons.
​Unique Features
​Codonanthe gracilis is particularly prized for its mutualistic relationship with ants, a unique ecological adaptation that makes it a fascinating addition to any collection. The showy, bright orange berries are also a standout feature, providing long-lasting colour and interest. Its cascading growth habit makes it perfect for hanging baskets or displaying on shelves where its beauty can be fully appreciated.
