About Royal purple allamanda
Brunfelsia grandiflora, commonly known as chiricsanango, is an ornamental shrub belonging to the Solanaceae family, native to South America. It is notable for its large, showy tubular flowers that change color, opening in deep purple hues before fading to lavender and white. It is ideal for tropical and subtropical gardens, or as a potted plant on patios and terraces, where its abundant blooms create a visual and aromatic spectacle.
Native range
Tropical South America, especially in the Amazon basin of Peru, Ecuador, Bolivia, and Brazil.
Care tips
It requires bright indirect sunlight or partial shade, especially in warm climates to protect its blooms. Watering should be regular, keeping the substrate moist but not waterlogged, reducing frequency in winter. It prefers rich, well-draining, slightly acidic soil. A common mistake is neglecting pruning, which can limit flowering and compact growth; prune lightly after the main bloom to encourage new branches and more flowers.
