Care tips

This plant thrives in full sun and well-drained soils, even poor or sandy ones, as it is native to dry regions. It requires very moderate watering once established, being susceptible to root rot if overwatered or if the soil retains too much moisture. Avoid transplanting once established, as its deep taproot does not tolerate disturbance well, which can lead to its decline. A common mistake is planting it in partial shade or heavy clay soils.
