Maryvonne, during the Lilac Days festival they have at least 30 varieties available in 3" pots for $5, next year I can send you some or anyone else some. I bought a couple this year and they've already doubled in size not going to bloom for a few years but the selection of varieties is the best I've ever seen. There was a cool variegated one that I've never seen before.
The most fragrant was Mt. Baker which is the white one totally covered with blooms in the photos.
Thanks for the compliments on the photos. I did take pictures of the name tags and will try to get them all labeled.
