Care
Watering
Keep the substrate moist but not saturated, especially during active growth. In winter or dry periods, reduce watering but don't let it dry out completely. Regular watering encourages generous flowering.
Light Exposure
Place it in bright light, ideally in partial shade in hot climates. It tolerates morning sun exposure, but protect it from harsh afternoon rays in very hot regions. Good light stimulates flowering.
Soil and Potting Mix
Use a substrate rich in organic matter, well-draining and slightly acidic. A mix based on forest soil, compost and perlite works well. Ensure good drainage to prevent root asphyxiation.
Fertilizing
Apply a balanced or potassium-rich fertilizer from March to September, every 2 to 3 weeks. Reduce applications in autumn and winter. Favor formulas designed for flowering plants to stimulate flower production.
Pruning and Shaping
Perform light pruning in late winter or early spring to maintain a harmonious shape. Remove dead or misplaced branches. Moderate pruning encourages branching and flower production.
Pests and Diseases
Watch for red spider mites and mealybugs, especially indoors or in dry climates. Excess stagnant moisture can promote fungal rot. Ensure good air circulation and monitor humidity levels.
Did you know?
Palicourea pyramidalis is highly prized in South American gardens for its striking yellow flower spikes, which spectacularly attract hummingbirds and pollinators. Its name 'pyramidalis' refers to the characteristic shape of its inflorescence, which is upright and dense. This plant embodies the botanical richness of humid tropical regions, where it flowers almost year-round.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
