Andrea, there are a bunch of pictures of BME seedlings on the Hosta Library Forums, posted by none other than Jane Deckert. So yes, they might well be fertile. And you're right, BME certainly has a reputation for not setting seed easily. I myself was tickled pink to see a pod developing on one of my BME's for the 1st time in 3 years, can't wait to try and sprout them next year!

I have seen a seedling of BME, so it is possible. I had no success trying to cross it with all kinds of different pollens.

I set pods and grew seeds three years ago on it. Last year nothing but seed pods again this year.

I posted some pictures of seedlings from BME on the other forum but this year I only have one pod.
