Care tips
It prefers a spot with partial shade or filtered light, avoiding direct afternoon sun which can scorch its leaves. Keep the substrate consistently moist but well-drained, especially during flowering, and ensure the soil is acidic to enhance blue hues. A common mistake is over-pruning; only trim spent flowers and weak or damaged branches after blooming to avoid compromising next year's buds.
