The wood is purple. Why would that be? Is it diseased? I did a quick google search and came up with nothing.

Any Green Thumbs Out There?
I was pruning a really old lilac bush in my backyard. I cut off a big, mostly dead branch and saw this:

No clue. You should email the guy at this site if you get stuck http://www.ext.nodak.edu/extnews/hortiscope/shrub/shrbcntnts.htm
I emailed my friend who is a hortoculturist. I'll let you know. :)
Bridget e-mail me this and I have taken a look but I have not found anything out for certain, but it is kind of sounding like Vertillium wilt or a cancer. From the pictures it could be a cancer with the large bulbous growth around were the discolorization is. Vertillium wilt is a soil borne disease that runs up through the sap from the roots. There is no real cure for any one of them except to cut out the infected areas, which looks like it will take out most of your lilac. But as long as the lilac is growing actively then you shouldn't have to really do anything. It looks like it has survived without any other treatment for many years. I think I would just let it keep growing and worry about it. It does seem to be a little rotten and my come down is strong winds or heavy snow. But just another side note is that the botanical name for lilac mean hollow for the easiness of hollowing out a branch of some species of lilac and this may just be one of those species. Hope this helps
