Trompettia cardenasiana Plant Care

Trompettia cardenasiana (Trompettia cardenasiana) belongs to the Solanaceae family within the Trompettia genus. Trompettia cardenasiana is native to Bolivia, growing in dry, Andean valleys at elevations of 2,000–2,500 m (6,600–8,200 ft) and 3,000–3,500 m (9,800–11,500 ft) and has been collected near the town of Cotagaita in Potosí Department.

Trompettia cardenasiana displays a vining, trailing growth habit, reaching up to 1.5 ft tall with a spread of approximately 2 ft. Trompettia cardenasiana produces tubular flowers in shades of purple and white.

Leaf size: approximately 4 inches.

Trompettia cardenasiana requires watering every 7–10 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Trompettia cardenasiana thrives in bright indirect light. Avoid placing Trompettia cardenasiana in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Trompettia cardenasiana grows best at temperatures of 65–80°F. Trompettia cardenasiana prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining loamy soil with added compost for nutrients. Good drainage is essential for Trompettia cardenasiana to prevent waterlogging, which leads to root rot and fungal issues.

Feed Trompettia cardenasiana every 6 months during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.

Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.
