|I purchased 2 assorted lilac syringa sp from one or your stores and I want to use them as a border separating our house from our neighbor. I would like to know how far apart should I plant them from one another? How big should I expect them to grow? thanks in advance.

|On average, lilacs will grow about 12 feet tall and 9 feet across at maturity, so allow plenty of space for your plants. They do best in full sun and with good air circulation, so space them at least ten or twelve feet apart.
