Cara's Nursery in Missoula have some beautiful Elderberry. I got mine there and it doesn't need another one to pollinate. I purchase "Sambucus Nigra-York". I live in a forest in Sanders County. If you have any deer about, they like it too. My EB was doing great making berries and flowers. And then, one morning all the flowers and berries had been harvested by the deer. Now they won't get sick maybe too. But I will have to fence it off so it can reach the height they won't distrub.
