Troubleshooting
Plant is wilting or rotting at the base
Check soil drainage; the plant is likely suffering from waterlogged roots in heavy soil.
Flowers are bending or falling over
Ensure the plant is receiving enough sunlight. If it is too shaded, it will stretch excessively to find light, becoming weak.
Plant is spreading too aggressively
Deadhead the spent flower spikes before the seeds have a chance to drop and scatter across the garden bed.

Setup, Compatibility & Care
Planting: Dig a hole twice the size of the 9cm pot and plant in a sunny location with neutral to alkaline soil.
Soil: Ensure the site has excellent drainage; the plant will not survive in heavy, wet clay.
Watering: Provide regular moisture until the plant is established, after which it becomes highly drought-tolerant.
Feeding: Minimal feeding is required; too much fertilizer can lead to weak, floppy growth.
Maintenance: Leave the seed heads if you want the plant to spread, or remove them immediately after flowering to prevent excessive self-seeding.
Care: Cut the plant back to the base after the foliage dies down in autumn or spring.
