I found this comment on a website that talks about growing them, although it's not specifically about "Bright Eyes":
"If you want to collect your own seed, tap the flowers that have been open a couple of few days, which shakes up the pollen and often is enough to pollinate the flowers.
Then simply trim off the tiny seedpods that will ripen about a month after flowers fade (Carefully, or see note about 'Broken Plants'); Place pod into a folded up piece of thin white paper and let dry for a day or so. when pods are realeasing the seed, shake out the pods into the paper with tweezers and remove the stems and debris. Make sure seed is completely dry, then store in refrigerator until planting if it will be more than a couple weeks. It takes very little seed to make dozens of plants, so share with friends! "
Here's a link to the webpage if you're interested:
