Comments on castor oil
Original by its flowers in thorny balls, castor oil is also cultivated as an annual. Relatively easy to maintain and to grow very quickly, it is nevertheless very fragile when the temperature is low.
Therefore, install it in a sheltered, sunny location.
It is recommended to soak the castor seeds for 24 hours in water before sowing.
