Ooh, those bring back memories☺
Nearly thirty years ago, I arrived at the house of some French friends on 1st May. Apparently, it is - or was - traditional to pick these in the woods, or buy some, on that date. My host had put a small vase of them in my bedroom, but that lovely scent was so strong that I had to remove them in the middle of the night!
Years later, I planted some in my back garden, but they failed to thrive. Meanwhile, some spread into the front garden from the house next door, and did so well that they became a pest, and I eventually had to dig them all out.
I seem to have something of a love-hate relationship with them!
