This is a very imposing annual plant, very easy to grow and spectacular to watch, due to its big yellow flowers, throny leaves, throny buds, and throny fruits. Once you establish the plant, it will resow automatically each year, and you will even obtain surpluss seeds for trading. Being an annual plant, it does not present problems for cold climates, but it may not be able to reach maturity in places where the summer period is very short.
Since the seeds of this plant germinate so easily, you can sow the seeds directly into the ground. Forget about complicated soil mixtures - keep it simple, the only requirement being that the soil has good drainage. Maintain the seeds wet at all times until they emerge, then reduce watering to a minimum (this plant grows in areas where there are no more than 3 inches of rain per year"). Expose to sun.
