Seed pods remain at the tops of the stems!

We just let the seed fall naturally and grow where it will. If you want to try growing in a pot, then wait until the pod begins to split. Sow the seeds in ordinary compost, cover with grit and leave in a safe, rodent free spot, outside over winter. They germinate in Spring. Do not prick out , feed with dilute liquid feed every 2 weeks or so, until the leaves dies down. If they are crowded in the pot, then put the whole thing in a bigger deeper pot. I do not even prick out the second year either, but carry on growing them in the same way. They may be separated and potted on the next Autumn. they take between 3 to 5 years to reach flowering size.
