We live in Colorado at 7200 ft. We have lilacs that bloom in May. On a garden tour, we saw lilacs that bloomed twice in the summer. We would like to know what type of lilac bush would also bloom later than May.
Yes, there are varieties that bloom more then once.
The Korean Dwarf Lilac is a good one to try. I have two of these myself in my garden and love the blooms that come in midsummer.
You can also look for the name, Bloomerang Lilac. These are trademarked plants that also are multiple bloomers.
