Mine flower regularly several times each year, but have never set seed. hey probably are not self pollinating. Hopefully someone else will clarify this?

The top green spathe will fall off and the lower pod will swell. When the seeds are ripe, the pod will split and you will see orange-red seeds. Pick the orange-red ones. Drop them in a pot and cover with sand or soil and put them in a warm, sunny place. They are so easy to grow from seeds.

Thank you so much!!
