I am also looking for the deepest purple lilac that is a very, dark grape color - the one I have seen in yards in Seattle, WA. I have a couple of shoots from my neighbor in Seattle, but I am not sure they are going to survive the transplanting. I have also looked at every website to find the name, but none of the pictures look like the ones in Seattle. I am wondering if the pictures of the dark purple ones do not really show the true color. I have been hoping that someone from Seattle will reply to this post with the name.
Any ideas for how to find an old variety from a specific location?
