That is a shame. I have seen them all over the place growing up tree's and
over my neghbors fence.They do take over, but we have forest behind us and
we were hoping to fill in some of the gaps with it.

Sounds ilke Wisteria to me, growing up trees, etc.

Sure does. Wisteria is a vine, lilac is a shrub. Please compare these

The last link is a photo of the Lilac cultivar 'Miss Kim' which does very
well here. I have a huge shrub in full bloom right now.
