Buckeyes leafing out
One of my favorite trees, the California Buckeye, heralds the arrival of the end of winter by leafing out by late February at lower elevations and even now at 1000' or so is leafing out. Compensating by hibernating for the summer, most individuals lose their leaves by June or July.
