Suitable pH: acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It prefers dry or moist soil and can tolerate drought.
A very drought resistant plant once established, it thrives in a poor gravelly soil. Nitrogen-rich soils produce excessive leaf growth at the expense of flowering. Prefers a sunny position.
