I have gotten some off of ebay

Doug Beilstein has seeds from streaked ones, so you will have a chance of variegation in the future. Seeds from variegated hostas usually produce solid color seedlings. I will grow seeds from own h.'Blueberry Waffels' looking for puckered blue seedlings. Seeds from Doug and later auctions will be fresh and probably have high germination rates.
