This Chilean plant is quite new to cultivation and is a most imposing annual plant. It very easy to grow, and spectacular to watch with its big yellow flowers and thorny, silvery leaves, buds and fruits. Once established, it will resow automatically each year only growing in spots it chooses and where it is happy, but never being a nuisance!
Sow in late winter/early spring in gentle warmth, 15-20 degrees C. Prick out into small 3" pots and plant in final position when the plants are establish. Also does well if sown where needed in May when soil is warm.
Classification:Half hardy annual
