Columnea sanguinea, known commonly as the "Flying Goldfish Plant" due to its vibrant, tubular flowers, is a striking epiphyte. It has cascading stems, making it well-suited for hanging baskets or ledges where it can trail. Its glossy green leaves serve as a backdrop to red to orange flowers, which attract hummingbirds in its native habitats but offer visual interest in indoor settings. With the right conditions, this plant can produce flowers throughout the year, although its heaviest blooming period is typically in spring and summer.
This tropical species requires a warm, humid environment to mimic its natural habitat. As an epiphyte, it appreciates a well-draining medium and good airflow around its roots. When placed in indirect light and maintained at the proper humidity levels, Columnea sanguinea can thrive indoors, displaying consistent growth and vibrant blooms.
Native to
Columnea sanguinea is native to the cloud forests of Central and South America, including Colombia and Ecuador. It typically grows as an epiphyte in the understory, attached to trees where it receives dappled sunlight and high humidity. The natural environment gives it some shade tolerance but also requires it to adapt well to lower light indoors.
Water
This plant prefers consistently moist soil but is prone to root rot if waterlogged. Allow the top layer of soil to dry slightly between waterings, particularly in the winter months when it may experience a slower growth period. During active growth and blooming periods, it may require more frequent watering, but always ensure drainage is effective.
Light
Bright, indirect light is ideal for Columnea sanguinea, though it can tolerate lower light levels. Avoid direct sunlight, as it may scorch the leaves, but provide ample filtered light to support blooming. South or east-facing windows are typically well-suited for this plant.
Humidity
This species thrives in high humidity, ideally around 60–80%, which can be challenging in standard indoor conditions. Regular misting or a pebble tray can help raise humidity, though a humidifier is most effective. Because of its high humidity needs, it is also well-suited for terrarium environments if grown in smaller sizes.
Temperature
Keep Columnea sanguinea in a warm environment with a range between 18–24°C. It does not tolerate temperatures below 10°C, so avoid placing it near draughty windows or doors during colder months. A stable temperature within the suggested range encourages consistent growth and flowering.
