We got a bouquet of cut flowers from someone attending a party we were hosting. It included this thing which I assume is a seed pod of some sorts. It feels sort of like a baloon in that it is obviously hollow inside. It is covered with small spines. It has also lasted a really long time - longer than any of the flowers in the bouquet by far.
Can anyone tell me what it is?
I believe I answered my own question. As luck would have it one of the pods split open the day I posted the question above. The seeds inside were brown and had "parachutes" attached. It looked a lot like some variety of asclepias (milkweed). A little googling this morning and I think I found it...a milkweed native to Africa that goes by a variety of common names that refer to the balloon-like nature of the seed pods.
