Has anyone have any problems next to a Sensation Lilac? I was worried that it might thieve off into my neighbors...

I was worried that it might thieve off into my neighbors patio.
Japanese Maple?
Answers:    I have this comeliness! Mine is only 2 years dated so it's still a baby and single about 4-5 foot tall and 2-3 foot wide. Lilacs carry wider over time but I don't see them re-seeding. If you give it plenty space, it shouldn't creep over into your neighbors yard.

Here is a join with some information: http://www.mobot.org/gardeninghelp/plant...
It give a spread of 6-12 feet. Again, they are slow to spread and you can sunken the plant each year.

Hope this help.
