Ideal Growing Conditions

Watering Needs
💧 Drought-Tolerant – Requires minimal watering once established.
- Water only when the soil is dry to avoid overwatering.
- In extended dry periods, occasional deep watering can enhance blooming.
- Avoid excessive moisture, which can lead to fungal diseases or root rot.

Care and Maintenance
