Sunlight: Requires full sun (at least 6 hours of direct sunlight daily)
Watering: Water moderately while young. Once established, it is drought-tolerant and only needs water when the soil dries out deeply; it strongly dislikes "wet feet" (especially in winter).
Pruning & Maintenance: Cut back faded flower stems after the first flush to encourage a second round of blooms. For perennials, trim back to ground level over winter dormancy. Taller varieties may need light staking or support netting so they don't flop over.
Placement: Choose a permanent home when planting so you do not disturb the taproot later
