I'd like to know, too--mine's blooming.

Well dogoneit someone tells us. For all we know thses may be flingers too....lol.

The photo at the link below shows the seedhead. After the flowers have dried up and dissappeared, there will be a shell like structure that looks something like a turtle's head or a parrot's beak. When they turn brown and dry they split and release the seeds. The seeds are fairly small and look like little discs with a swelling in the middle. There are lots of them in each seedhead.
