This is what the seed pods look like after the flowers are gone. The pods are still green yet.
Now when the pods turn sorta brownish, you can see the pointy tips start to open and show the seeds inside.
Now just tip this pod over and wiggle it around and all the seeds will pour out. And you have this:
You can easily get 50 seeds per pod.
Seeds need light to germinate so dont cover them. You can sow them this time of year like mother nature would, winter sow them. They need stratification if you sow them in spring. Winter sowing works ideally for this type seed.
