Care tips
This plant thrives in full sun for abundant flowering and prefers well-drained soil, ideally fertile and rich in organic matter. Watering should be regular, keeping the substrate moist but not waterlogged, especially during warm and dry periods. To encourage continuous blooming and maintain a compact shape, light pruning after each flush of flowers is recommended. Avoid low temperatures, as it is sensitive to frost and prefers warm climates.
