A long time ago–an embarassing number of years–more than you need to know, I worked at the Arnold Arboretum of Harvard University in Boston in the United States. Their specialization was woody plants.
They have four hundred named cultivars, varieties and species of lilac (Syringa). Each spring they have a massive public event that huge crowds attend–Lilac Sunday. The event timing varied as climate related events do. Early warm spring meant early lilacs could be mid-late April. Cold and a late spring meant late lilacs could be mid May.
So we watched carefully each year to determine accurately when would Lilac Sunday be.
All that crossed my mind as I was looking and enjoying lilac fragrance everywhere in my home town today. So if I was to call Lilac Sunday, I’d call it this week–Mother’s Day in the USA.
And the climate? A normal average year.
Go out and find a lilac. Enjoy the blooms and their fragrance. They go by rather quickly as May warms the earth.
For a virtual visit to the lilacs at the Arnold Arboretum, there is a 3 minute video at this link here (Mask not required).
