✂️ Care
Plant the stems in the background zone. Lots of light is essential for the most beautiful scarlet red leaf color. Prune regularly — cut off tops can be replanted for a fuller result. Liquid fertilizer such as Sera Florena supports healthy growth.
💡 Planter tip
The scarlet red underside of the leaf is best showcased with strong top-down lighting. Combines beautifully with light green plants for maximum color contrast in the background zone.
