Good topic, Deb! I was going to throw out the "phenology" word but Caroline beat me to it
Here's some info about lilacs that I found somewhere, at some time, and saved:
"A number of observations correlate with various stages of the common lilac: Crabgrass seed germinates at the time lilac is in the early stages of bloom; when the lilac has leafed out it's time to plant lettuce, peas and other cool-weather crops; when the lilac flowers are in full bloom, plant beans, cucumbers and squash; when the flowers have faded, plant melons."
