Care tips
This plant thrives in partial or dappled shade, especially in warmer climates, to protect its leaves from direct sun. The soil must be acidic (pH 4.5-5.5), well-drained, and rich in organic matter, kept consistently moist but not waterlogged. Avoid planting in alkaline or poorly draining soils, as this can lead to chlorosis and root rot. Protect from strong winds and late frosts that can damage flower buds.
