Planting & Care

For aquarium use, sow seeds in a nutrient-rich substrate or fine gravel and keep them consistently moist or lightly submerged during germination. Provide bright, intense lighting to encourage strong growth and red coloration. Maintain stable water conditions and avoid sudden temperature swings. Once seedlings develop roots and several leaf pairs, they can be carefully transplanted to their final position.

For water gardens or paludariums, sow seeds in moist, boggy soil at the water's edge or in shallow water. Keep the substrate consistently wet and provide full sun for best color development. Thin or space seedlings as they grow to prevent overcrowding. Regular pruning of taller stems encourages bushier growth and helps maintain an attractive shape.
