Brad, I have one lavender Buddleia which produces numerous seedpods, but my dark purple one doesn't produce them nearly as frequently, but then I usually cut off the dried flowers right away anyway to prolong flowering when I can.

The seedpods are very small, but they are noticeable, and they do look different than a dried flower stalk. The pods are stiff and upright, and the seeds are like soft tiny feathers. When the pods look dry and split open slightly, cut off the branch and put in a paperbag and shake the seeds out, or you can shake the seedpods or crush them over a planting medium.

As a matter of fact, I just cut off some green seedpods today before they ripened and dispersed the seed. I dug them out of the recycle trash and took a picture of them so you could see what they look like before they become dried.
