butterfly weed (seed pod harvest)?
How do you know when you can harvest the seeds from the seed pods on the butterfly weed? Do you have to wait till the seed pods are dry and cracking open like Milkweed does?
Also, are there male and female plants of Butterfly weed? I have 10 or 12 plants and so far only one of them has pods and it just happens that the one with the pods had very few flowers so it was quite a surprise. The plants with an abundance of flowers have no pods at all.
