One of my strongest scent memories is of blooming lilac in springtime in my hometown Buffalo, NY.
We had a large lilac bush outside my childhood home, but lilac bushes are everywhere in Buffalo.

There is a dramatic blossoming event that anyone who has witnessed will remember.
The reason it’s so extraordinary is that Buffalonians will have just come out of a very long, grey, and cold winter (as always) and the blooming flowers mark the beginning of the new season.
The lilacs are so pungent, wafting through the air, and with the warm spring temperatures everyone’s windows will all be open.
I have such a strong memory of this springtime olfactory event, that no lilac interpretations in perfumery have accurately represented it for me.
