Hello,
After a long internet search, I found a grower, HorizonHerbs.com in the USA which grows their plants from seeds. They have Bilberry Plants (Vaccinium Myrtillus) 3-4 years old available for purchase. They also have seed packets. I purchased both. Their internet site mentions only the Bilberry seeds, but if you e-mail or call them, they can tell you about their Bilberry plants. Bilberry plants have to be at least 3-4 years old before they bear fruit. You can reach them at this link:

Also, this grower is especially careful to maintain high quality standards. All of their seeds are heirloom organic AND non-genetically modified. I hope this helps. I don't know why it is so hard to find Bilberry in this country but this source has them available in the best form possible!!!
