G.H., is milk-weed that plant that has a long stalk and these almond shaped buds at the top, about four inches long, that if you open-up have a whole pile of soft downy fluff inside?

I think I've read that there are 200 kinds of milkweed species worldwide. I've planted Asclepias Tuberosa.

It has orange flowers and the seed pods have down inside, yes. When they open the seeds fly away on their own individual down.
