May 1 - May 31 Will you be the top lilac observer this month?

June 1 - June 19 (last day of spring)

Why you should consider purchasing a cloned lilac this month: Data on cloned lilacs have been collected for decades. Some of these plants have died. We need to replenish the pool! If you'd like to purchase a cloned lilac to monitor, you can buy cloned lilac from our friends at Jung's Nursery today (2 for $20).

Steve Potter shares why he observes

"My wife and I are cooperative observers for the national weather service and we record weather data everyday, so it seemed like a natural fit to include phenological observations."

Your lilac data are getting used! Find out what your lilac observations have to do with the White House.

If you've ever wanted to track species that were not on our list -- search for species to see if we've added them! There are nearly 900 species available now.
