Cultivation Methods
Heliotropium hirsutissimum Vatke, also known as the hairy heliotrope, is a perennial plant native to Africa. It can be grown in a wide range of soils, including sandy loam, clay loam, and rocky soils. Hairy heliotrope grows best in well-draining soil and prefers full sun exposure. It can tolerate slight shade but needs at least six hours of direct sunlight daily.
