Care essentials
Amethyst Flower thrives in partial shade and tolerates full shade in NE Florida — one of few flowering annuals that performs reliably where sunlight is limited. Protect from harsh afternoon sun to prevent leaf scorch and extend bloom.
Keep soil evenly moist but well-drained; avoid overwatering, which reduces flowering and encourages foliage at the expense of blooms. In NE Florida's warm season, check soil moisture every 2–3 days and water when the top inch is dry.
Plant in well-drained sandy or loamy soil amended with compost to retain some moisture. Apply a balanced slow-release fertilizer at planting; avoid excess nitrogen. In containers, feed with a diluted balanced liquid fertilizer every 4–6 weeks during the growing season.
