Interesting assortment of lilacs. Names definitely add some curiosity to the arboretum. Gives the lilacs some personality - back stories 🙂 We had lilacs when we lived in Minnesota. I haven't found any around the yard here but I am seeing them all around the area. I've been talking to my wife about planting some. Maybe on the edge of the woods. I agree with you they do smell wonderful.
If btc moons someday I would setup an arboretum of lilacs with some bee boxes nearby to see if the honey gets some of that unique fragrance in it.
