Lilac Growth Rate

Question

I am thinking of planting a lilac. I saw a white one in a nursery and was told that they “grow fast.” If the plant starts out 3 feet tall, how long will it take, on average, to get 3 feet? 4 feet? It will be in my backyard with full sun almost constantly. I live in Southern California so the weather is pretty much constant, in the 70’s and 80’s all the time.

Answer 1

On average, most lilac varieties are medium growers, meaning they grow about one to two feet annually.
