A very beautiful and spectacular plant and easy to raise from seed. Collect the seed just as it turning from green to black, usually late September early October and sow immediately with a little bottom heat.
If you time it right all will germinate and you will get hundreds of new plants if you can be bothered to prick them all out. Grow on under cover if you can and mass plant in the spring. They will usually flower the following summer and make much bigger plants the next year
