A common lilac, the suckers also have curled leaves. It has a few blossoms, they seemed to open and then died quickly. Please help! The branches are also scaled.

Thanks for your question. The most common reason that lilacs have cupped/deformed leaves is because an herbicide has drifted over to the plant. Here is an Extension article explaining how it happens: https://hort.extension.wisc.edu/articles/herbicide-damage/
Hope this is helpful. Good luck!
