The seed heads are not as tidy as those other species, but I think they're both interesting and attractive when you get close enough.

The brown things sticking up seem to be left over flower parts. They're just papery husks that come off with the slightest provocation.
The seeds themselves are almost completely hidden from view in the photo above. There are about 20 of them, standing on end, each with its own "parasail" to catch the wind. That's assuming that the seeds ever actually get separated. They seem to be pretty thoroughly interleaved and I'm not sure just what it takes to get them apart!
Here is an individual seed.
38mm Olympus bellows lens at f/5.6, minimal stacking just to cover the seed itself.
You can see that the fibers of the sail are sort of feathered.
Here's what the fibers look like at much higher magnification (about 140X, as shown here).

I have tons of these things growing at the edge of the front yard near the woods but have never given them much thought, except for cutting a gall or two open to see what was inside of them, not much this time of year but who knows.
